Roflam P LO is a commonly used flame retardant known as TCPP. It occurs in the form of a colourless liquid with low dynamic viscosity, which makes it compatible with many liquid raw materials. It is dedicated primarily to polyurethane plastics, especially for flexible foams, where high requirements for the emission of volatile organic compounds are in force.
The purpose of using Roflam P LO is to reduce the flammability of the material. It increases the resistance of the material to the fire and reduces the speed of spreading the flame in the case of burning of the material. Due to the high content of phosphorus and chlorine in the molecule structure, the product inhibits the combustion process both in the gas phase as well as in the solid phase. In the gas phase, it inhibits the reactions responsible for the spread of fire. In turn, in the solid phase it creates on the surface of the material a charred layer, which cuts off the access of oxygen from the environment, thus limiting the burning of the material. The simultaneous operation in both phases makes the Roflam P LO one of the most effective flame retardants compared to the available solutions.
Additional strengthening of the flame retardant effect is achieved by the use of Roflam P LO with powder flame retardants, i.e. antimony trioxide, melamine, aluminium hydroxide or magnesium hydroxide. By using them together, due to the synergy effect, even the most stringent flammability requirements can be met.
Roflam P LO is primarily used for the production of standard and high-resilience flexible polyurethane foams with enhanced fire resistance (CME – Combustion Modified Ether foams; CMHR – Combustion Modified High Resilience foams). The product ensures effective flame retardation of foams with different densities and levels of hardness. It works perfectly in moulded foams as well as block foams. Flame-retardant foams are used, among others, for the production of mattresses, pillows, armchairs, sofas and car seats. Roflam P LO is also used in semi-rigid foams, which serve as acoustic materials in transport.
Products containing Roflam P LO achieve positive results in flammability tests, among others in the automotive industry (e.g. FMVSS 303) and furniture industry (e.g. BS 5852). Due to the low emission of volatile organic compounds (VOC), the product meets the high requirements for transport. In addition, unlike many solutions available on the market, Roflam P LO, due to the effect of flame retardation, preserves the appropriate physico-mechanical properties of PU foams.
