Plastics

Nowadays, plastic has been to the indispensable part in our life, and due to the potential risk of fires, there is the wide needs on flame retardancy .

Generally speaking, flame retardants used in these applications may obviously reduce the heat deflection temperature of the plastic and take effect on other properties like mechanical properties and electrical properties. Presafer flame retardants not only has high efficiency but also take other properties into consideration. Flame retardants from Presafer have characteristics as below.

▼ less mold corrosion

▼ good dispersity and flowability

▼ great electrical property

▼ anti-migration

Compatible system:

PP, PE, PA, PBT, TPU, EP, UP, PP/glass fiber, Composite material,

Drip Promotion or Drip Suppression

The flow properties of molten thermoplastics during ignition or flaming can play a large part in flame retardant modes of action.At the ignition step,melting or shrinking away from the flame can prevent ignition, this being amode by which thermoplastic textiles can pass a flame test such as NFPA 701or the childrens’ nightwear standard. Solids (such as infusible pigments or the inclusion of infusible fibers) that prevents the flow can aggravate flammability. This is discussed further in the textile chapter. The same effect may be seen in thermoplastics other than textiles.

A relatively weak flame retardancy standard such as UL 94 V2, which allows even flaming drips, can usually be passed by such systems as foamed polystyrene or non-reinforced nylons. In the case of the foamed polystyrene, inclusion of a small amount of a peroxide or other free-radical-generator which favors fragmentation, can favor the melt-flow-drip mode of extinguishment. In the case of nylons, melamine cyanurate is commonly added to favor non-flaming drip; the presence of a reinforcing solid can defeat thismode of extinguishment. On the other hand, melt flow leading to flaming drip is not allowed in some important test standards such as UL 94 V0 or V1. The most usual means to retard it is to include small (< 0.5 %) amounts of a finely-divided shear-fibrillated polytetrafluoroethylene.Finely divided silica or clay can also be used for this purpose.

Fireproof Coating

In homes, office and public buildings, if there is the building material without protection, once breaking out of fire, the building material such as steel structures, metal sheets, wood, plaster and concrete will gradually lose intensity and become easy to collapse. However, if these building material are coated with special coating, then the heat would be blocked, which will lengthen the survival time.

Presafer high polymerization ammonium polyphosphate (EPFR-APP series) can provide protection for these building materials. Compound with acrylic resin/epoxy resin/polyurethane resin, EPFR-APP series can be used to make the ultra-thin intumescent fire-proofing coating, and in this respect, presafer has rich experiences, which can help customer to figure out the special solution in a cost-saving and efficient way, and meet the fire protection requirements and achieve other regulation.

Compatible system:
Ultrathin intumescent fireproof material

Textile

According to the research on the fire causes, improper textile will help fire spread. Now in the world, there have been the fire protection requirements regulated indomestic and foreign standard. Different end use of textile complies with different flame retardant requirements. For example, in USA, the textiles used in the automotive component must pass FMVSS 302. In Europe, the textile used in building must satisfy ISO 13501. Therefore, it will be wise to choose the flame retardant based on the textile’s end uses.

Compatible system:

Aqueous coating for textiles, oily coating for textiles.
