Flame retardants.


Polyurethane polyurethane

Any of a class of very versatile polymers that are made into flexible and rigid foams, fibres, elastomers (elastic polymers), surface coatings, and adhesives.
 formulators are said to enjoy improved processing and lower heating costs thanks to an innovative low-viscosity flame retardant Flame retardants are materials that inhibit or resist the spread of fire. Naturally occurring substances such as asbestos as well as synthetic materials, usually halocarbons such as polybrominated diphenyl ether (PBDEs), polychlorinated biphenyls (PCBs) and chlorendic acid  technology from the company. The low-viscosity products, Saytex RB 9000 series flame retardants, are said to reduce the high viscosity of the flame retardant component in brominated polyols, giving formulators more freedom to use materials in their formulation that could not have been used previously, and thus more flexibility in developing new formulations, according to according to

 the company. Phosphate flame retardants formerly carried the dual role of flame retardant additive and viscosity reducer. With the low-viscosity RB 9000 series products, more brominated flame retardant Brominated flame retardants are produced synthetically in 70 variants with very varying chemical properties. There are several groups:
  • polybrominated diphenyl ether or PBDE (DecaBDE, OctaBDE, PentaBDE),
  • polybrominated biphenyl, or PBB
 can be added to the formulation, increasing flame retardant properties and reducing smoke generation, according to the manufacturer. Saytex RB 9130 flame retardant was designed to provide relatively low viscosity characteristics with a lower hydroxyl hydroxyl /hy·drox·yl/ (hi-drok´sil) the univalent radical OH.
