Skum med høj modstandsdygtighed

Silikone til HR -skum/silikone overfladeaktivt middel XH - 2815

Silicone for HR foam/Silicone surfactant XH-2815

Kort beskrivelse:

WynPUF® from TopWin are all phthalate free and can provide very open foam. The surfactant has better balance in the cell regulating and stabilizing. As silicone surfactants for high resilience mold foam, it should have the three following requirements besides the universal properties of surfactants.

• As the automobile mould is becoming more and more complicated, the system material should have better flowability.

• In the process of foam production, there must be reasonable pressure in the mold for the convenience of demoulding and the safety of production equipment. And furthermore, foam products must be easily crashed by force or vacuum after demoulding. This requires that the silicone surfactants have good cell regulation and reasonable stability. The foam products not only have excellent surface and sub- surface, but also be easily demoded and crashed.

XH-2815 is equivalent to L-3639, 3002, 3002J, 3001; DC-2585, 2525, SI-2302 in international markets.
