Wear-resistant reinforced compounds - POTICON®

Otsuka Chemical Company Ltd manufactures and commercializes POTICON® grades, which are a series of compounds of plastic resin reinforced with microfibers of a Potasium Titanate called TISMO®, by means of a proprietary technology developed by our mother company.

These microfibers form a 3D network which confers reinforcement at microscopic level. The results are a high dimensional stability, a very low abrasive behavior and good sliding effect due to its superior smooth surface compared to other reinforcement fibers. Due to the small size of the fibers it especially suitable for high functional parts requiring dimensional accuracy and strength in good balance.

POTICON® compounds show very good tribological properties with superior friction and abrasion resistance and very good sliding properties without lubricants needed. It has a very low friction effect to aluminum and other metal counterparts as well as other plastic parts.

The main applications of use are gears, bearings, control cables, clutches and other where sliding properties are needed.

Some POTICON® grades can also be formulated to meet high thermal resistance, good reflectance of white light and resistance to ageing (whiteness), which makes them useful to manufacture some LED parts.

Titanate functional fillers - DENTALL and TISMO

Otsuka Chemical Co. Ltd. manufactures and commercializes several products as a specialist in Titanate chemistry. Our most representative products are DENTALL WK and TISMO.

DENTALL WK is a microscopic potassium titanate that can be used as reinforcement filler. It is covered with a nanometer-thin conductive layer. DENTALL WK has stable and homogeneous conductivity under diverse environmental exposures. Our products offer a wide range of conductivity which is consistent and easy to control.

DENTALL can provide conductive properties to paints, primers for plastic parts and plastic compounds and formulations and is specially used for white and pale colour formulations due to its high whiteness.

The second representative product is TISMO. It is a microscopic potassium titanate fiber used for reinforcement. There are three most important features which characterize its uniqueness: micro fine size, high strength and low hardness.

The diameter of TISMO is below 1 micrometer and length is in the range of 10-20 micrometers. Although TISMO fiber is significantly smaller than glass fibers, its tensile strength and tensile modulus are significantly bigger.

TISMO Mohs hardness is lower compared to glass or carbon fibers. Our product is a soft reinforcing material compared to the hardness of softer metals like aluminum. This softness character results in TISMO fibers being less abrasive effect on metallic parts in case of direct contact. This makes plastic compounds reinforced with TISMO as suitable candidates for metal parts substitution in automotive or electric/electronic devices with sliding parts.

Specialty additives - SPB-100 / RUVA-93 / 3,5-DMP

Otsuka Chemical Co. Ltd. manufactures several specialties which can be used as additives for plastic formulations:

SPB®-100 is a highly efficient halogen-free flame retardant. It is used as an additive for epoxy resins and polycarbonates, as well as other engineering and high performance polymers. SPB®-100 shows a great stability at high temperatures and a predominant resistance to hydrolysis due to its sterically protected, highly packed molecule. Its main uses are in high value-added products for transportation, electric & electronic and medical devices applications.

RUVA®-93 is a reactive UV-A protective agent that can be copolymerized with acrylic and styrenic monomers. It integrates in the polymer chain, so it does not bleed out to the resin surface, shows no transpiration effect at high temperatures. Furthermore, it cannot be extracted by water, acid or base solutions, alcohols, solvents or oils. RUVA®-93 provides excellent and time durable stability against UV-A radiation to end plastic products like thin films, fibers, inks or coatings.

3,5-Dimethyl Pyrazole (3,5-DMP) is a blocking agent for Isocyanates, that can be used in the manufacturing of 1-component Polyurethane systems. Unlike other alternative blocking agents like MEKO or Caprolactam, 3,5-DMP features a low unblocking temperature (110-120 ºC) which helps in keeping very good stability and lower yellowing/ageing for the end product. This is useful for end applications which are sensitive to temperature like coatings, etc.
