The term nylon refers to a family of plastics. The two most common grades of nylon are Nylon 6 and Nylon 6/6. The number refers to the number of methyl groups (See "A Guide to Polycarbonate in General" for an example of a methyl group) which occur on each side of the nitrogen atoms (amide groups). The term polyamide, another name for nylon, reflects the presence of these amide groups on the polymer chain. The difference in number of methyl groups influences the properties of the nylon.

Nylon is crystalline in nature; so the molecular chains do not have large substituent groups (such as the phenyl ring in polycarbonate). The crystalline nature of the material is responsible for its wear resistance, chemical resistance, thermal resistance, and higher mold shrinkage.

PA 12

Polyamide 12 (PA12) is formed by the polymerisation of laurolactam, a ring-shaped, long-chain monomer with 12 carbon atoms. Laurolactam, often called lactam 12, is obtained in a complex, multiple-step process from the basic raw material butadiene.

The properties of semicrystalline polyamides are determined by the concentration of amide groups in the macromolecule. This is lower in PA 12 than in all other commercially available polyamides, which accounts for its special properties:

Minimal water absorption: molded parts show almost no dimensional changes with variation in atmospheric humidity.

Extraordinarily high impact resistance and Charpy notched impact strength, even well below freezing point

Good to excellent resistance to greases, oils, fuels, hydraulic fluids, and many solvents as well as to salt solutions and other chemicals

Excellent resistance to stress cracking, even for metal parts encapsulated by injection molding or embedded into the plastic

Excellent abrasion resistance

Low dry sliding friction coefficient as compared with steel, polybutylene terephthalate, polyacetal, and other materials

Noise and vibration damping properties

Excellent resistance to fatigue caused by frequent load change

Easy processability

Thanks to these properties, the applications of Nylon 12 range from sophisticated line systems for motor vehicles, through large-volume pipes as are used in crude oil production, core insulation in the cable industry, and catheters in medical technology, to precision injection-molded parts like impellers and control-valve housings in machine and equipment manufacture.

What is PBT?

The letters PBT stand for polybutylene terephthalate, an engineering thermoplastic.

What are the properties of PBT?

PBT has a high crystallinity which determines much of its properties. PBT has low polarity and thus low water absorption. PBT is degraded by prolonged exposure to hot water or steam via chemical reaction. PBT's high crystallinity gives it excellent chemical resistance to most organic solvents. At low temperatures (less than 130°F), PBT has excellent wear resistance. Its electrical properties are stable under varying conditions. PBT takes fillers and additives well, and it can be dyed. Properties of PBT include the following:

good physical properties
excellent wear resistance
excellent chemical resistance
high heat resistance (reinforced grades only)
opaquemoderate pricefair processing

What are the applications of PBT?

An important application of PBT is keyboard buttons. PBT has the wear resistance, chemical resistance, and strength for the application; and perhaps more importantly, it can be dyed. With other plastics, it was necessary to make a separate mold for each button. Since PBT can be dyed, one can use a single mold for every button; and the graphic for a particular button can be died onto the button by a process called sublimation printing. Typical applications of PBT include the following:

typewriter, computer keybuttons
gears, cams, and bushings
electrical bobbins and rotors
electrical connectors and relays
pump housings and impellers
auto distributors and starters
automotive headlight brackets

What is polycarbonate?

Polycarbonates are long-chain linear polyesters of carbonic acid and dihydric phenols, such as bisphenol A.

What are the properties of polycarbonate?

Before starting to list properties of polycarbonate, it is probably wise to explain why the properties are the way they are. First, the technical stuff. Take a look at the above diagram. In it, you will see two six-sided structures. These are called phenyl groups. You will also see two groups identified by the label CH3. These are methyl groups. The presence of the phenyl groups on the molecular chain and the two methyl side groups contribute to molecular stiffness in the polycarbonate. This stiffness has a large effect on the properties of polycarbonate. First, attraction between of the phenyl groups between different molecules contributes to a lack of mobility of the individual molecules. This results in good thermal resistance but relatively high viscosity (i.e., low melt flow) during processing. The inflexibility and the lack of mobility prevent polycarbonate from developing a significant crystalline structure. This lack of crystalline structure (the amorphous nature of the polymer) allows for light transparency.

Now for the clearer, less technical version of the properties. Polycarbonate is naturally transparent, with the ability to transmit light nearly that of glass. It has high strength, toughness, heat resistance, and excellent dimensional and color stability. Flame retardants can be added to polycarbonate without significant loss of properties.

The general properties can be summarized as follows:

excellent physical properties
excellent toughness
very good heat resistance
fair chemical resistance
moderate to high price
fair processing

How do these properties compare to other materials?

One of the biggest advantages of polycarbonate is its impact strength. The following diagram compares the impact strength of polycarbonate to other commonly sold plastics.

Polycarbonate does have its disadvantages. It has only fair chemical resistance and is attacked by many organic solvents. It is also fairly expensive compared to other plastics. It has been as much as double the price of ABS. In applications where lower heat and impact are needed, ABS can be quite a bargain compared to polycarbonate.

What is a glass fiber reinforced grade of polycarbonate?

The addition of glass fibers to polycarbonate significantly increases the tensile strength, flexural strength, flexural modulus, and heat deflection temperature of the polycarbonate while causing a decrease in the impact strength and tensile elongation. (See Glossary of Plastic Properties for an explanation of each term.) The greater the amount of glass fiber added to the polycarbonate, the greater the effect on each property will be.

How is polycarbonate used?

It can be injection molded, blow molded, and extruded and is an ideal engineering plastic with good electrical insulating properties, finding applications in electric meter housings and covers, casket hardware, portable tool housings, safety helmets, computer parts, and vandal-proof windows and light globes. The price of polycarbonate restricts its use to mainly engineering applications.

Other engineering applications include the following:

equipment housings
exterior automotive components
outdoor lighting fixtures
nameplates and bezels
non automotive vehicle windows
brackets and structural parts
medical supply components
plastic lenses for eyeglasses

What is PC/ABS?

A compounded blend of Polycarbonate and ABS. The PC contributes impact and heat distortion resistance, while the ABS contributes processability and chemical stress resistance, and cost reduction below PC.

What are the properties of PC/ABS?

Properties of PC/ABS include the following:
impact resistance between ABS and PC, (10-14 ft.-lb./in.)
strength and stiffness between PC and ABS
heat resistance superior to ABS, less than PC
flame retardant system more stable in processing than ABS
very good indoor UV light color stability
low temperature impact and ductility
superior processability to PC

When should PC/ABS be used?

PC/ABS should be used for appearance housings, and structural parts which need stiffness, gloss, impact and heat resistance which is higher than ABS, but requiring costs below Polycarbonate. Housings requiring UL V0, but not 5VA-that is, portable electronic devices, not permanently fixed electric devices are also good applications for PC/ABS. Others include appearance parts requiring color fastness under interior UV light, automotive interior parts where temperature environment is between 180 F and 230 F - "above the beltline" applications, and where non-shattering ductility is required like instrument panel retainers. Applications such as painted exterior automotive parts requiring low temperature impact greater than 10 ft.-lb./in. is another place PC/ABS should be used. Any outdoor application should be painted.

What is made with PC/ABS?

portable appliances, flashlights, phones
laptop computer cases
keyboards, monitors, printer enclosures
automotive instrument panel retainers
wheel covers
small tractor hoods
non-professional safety helmets

What is PC/PBT?

A compounded blend of Polycarbonate and PBT. The PC contributes impact, stiffness and heat resistance, while the PBT contributes chemical resistance. The usual moisture sensitivity of the crystalline PBT is overcome by the PC in the blend. Some grades are made using PET instead of PBT.

What are the properties of PC/PBT?

impact resistance
low temperature impact resistance, ductility
heat resistance
chemical resistance

When should PC/PBT be used?

PC/PBT is effective where impact and chemical resistance is needed, and where low temperature impact, requiring a ductile failure mode (non-shattering breaks) is necessary. Applications such as bumpers and body moldings on autos and lawn & garden equipment, where toughness and resistance to stress cracking from fuels and lubricating fluids is required are good uses for PC/PBT. Parts made with PC/PBT are generally thick sections, as material does not flow well enough for thin wall design. The shrinkage varies based upon the relative content of the PBT, and therefore tool may be unique for this material, that is, it is not easy to substitute it for other polymers.

What is made with PC/PBT?

automotive bumpers
automotive side moldings
lawn and garden tractor hoods
hand tool housings
irrigation components
wiring connectors (PC/PET)

What is PPE?

The letters PPE stand for polyphenylene ether. Polyphenylene ether is a polymer characterized by regular, closely spaced phenyl groups (the same circular structures that are in polycarbonate). In general practice, PPE will indicate that a material is a modified polyphenylene ether. The modification of PPE involves the blending of a second polymer which is usually polystyrene or polystyrene/butadiene. PPE is similar in chemical composition to polyphenylene oxide (PPO), and they are generally treated as equivalent materials.

What are the properties of PPE?

very good physical properties
good heat resistance
poor chemical resistance
very stable dimensionally
poor color stability
opaquemoderate price
somewhat tough processing

What are the applications of PPE?

The strength, stability, and the acceptance of flame retardants of PPE (and PPO) makes them desirable for machine and appliance housings. The lack of chemical resistance and color stability means they often have to be painted in these applications. Low water absorption leads to their use in many water handling products. PPE can also be electroplated in automotive wheel covers and grills. Here is a summary of PPE applications:

internal appliance components
brackets and structural components of office products
large computer and printer housings (painted, foamed)
automotive wheel covers, plated
high tolerance electrical switch boxes and connectors
