Silicone for HR foam/Silicone surfactant XH-2833

short description:

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-2833 is equivalent to L-5333, 3636, 2118, 5309J; B-8681,8716, 8707; DC-6070, in international markets.

Product Details

WynPUF^®XH-2833is designed especially for high resilience (HR) flexible slabstock foam. It shows exceptionally high efficiency and is therefore particularly used in TDI high resilience (HR) formulation.

Key Features and Benefits

● Provide high stability, resulting in low setting in HR slabstock formulation.

● Yield open celled, high breathability foam with wide processing latitude.

● Achieve high efficiency in HR slabstock foam applications.

● Suitable for SAN and PHD polymer system

● Offer superior emulsifying for excellent foam component mixing.

Typical properties

Appearance: Clear liquid

Viscosity at 25°C：5-20CST

Density@25 °C：1.01+0.02 g/cm³

Water content: ＜0.2%

Levels of Use (additive as supplied)

WynPUF^®XH-2833 recommended for HR slabstock. The detail dosage in the formulation depends on several parameters. For example, density, the temperature of the raw material and contents of crosslinker. However, recommended use level in the formulation is about 0.8-1.0.

Package and storage stability

190 kg drums or 950kg IBC

WynPUF^®XH-2833 should, if possible, be stored at room temperature. Under these conditions and in original sealed drums, has a shelf-life of 24 months.
