Silicone Surfactant for Flame Retardant Foam XH-2950

short description:

WynPUF® is our brand for polyurethane foam additives. Some customers often require combustion foams that are required to pass flammability tests. By choosing flame retardants, special additives and silicone surfactants, the flammability and weight loss during burning can be dramatically reduced and combustion tests can be passed.

XH-2950 is equivalent to DC-5950 in international markets.

Product Details

WynPUF® XH-2950 is a low to medium efficiency, non-hydrolyzable silicone surfactant designed for flexible polyether slabstock foam. It provides superior flame-retardant properties compared to other silicone surfactants.

Typical properties

Appearance: Yellow to colorless liquid

Viscosity at 25°C:400-800CST

Density@25 °C:1.03+0.02 g/cm3

Water content: <0.2%

Key Features and Benefits

● Synergistic effects with flame retardant, allowing a reduction in flame retardant use levels while maintaining FR properties or improve the FR properties in the same level of flame retardant.  

● Can help foam to meet the demands of BS 5852/ Crib V and TB 117.

● Excellent emulsification to provide better nucleation, finer and more open cells, and better foam physical properties.

● Suitable for SAN and PHD polymer system

● Wide processing latitude.

Levels of Use (additive as supplied)

WynPUF® XH-2950 surfactant is recommended for flexible slabstock applications with FR requirements. A Crib 5 rating in accordance with BS5852 can be achieved by utilizing XH-2950 surfactant in conjunction with appropriate flame retardant. The recommended use level is 1.0 pphp.

Package and storage stability

200 kg drums or 1000kg IBC

WynPUF® XH-2950 should, if possible, be stored at room temperature. Under these conditions and in original sealed drums, has a shelf-life of 24 months.
