SY- 220 is a polyether polyol BHT-free. Widely used in the preparation of polyurethane elastomer, adhesive, waterproof coating, sports paving material etc. The polyether has good miscibility with water and isocyanate, suitable reactivity, low odor, and greatly improved foam process stability.

Storage
- Store in dry, well-ventilated and cool warehouse under 50ºC;
- Avoid of direct sunlight, rain, far from water and fire.
- Quality will be affected if store in temperature more than 60ºC for long time, no big influence if temperature going up or down in short time.
- Non-flammable & non- explosive products.
Widely used in the preparation of polyurethane elastomer, adhesive, waterproof coating, sports paving material etc. The polyether has good miscibility with water and isocyanate, suitable reactivity, low odor, and greatly improved foam process stability.
