Flextane F822 is a polyether polyol with three degree of functionality, high molecular weight, and high activity, which is synthesized by phosphazenium catalyst. The product has no BHT or amine and shows low unsaturation degree, low smell and low VOC. It is especially fit for the production of foam with low density and high resiliency. It can reduce the use level of polyhydric alcohols for polymer of the formula system, and can remarkably raise the carrying performance of foam.

Storage and transportation
Packed by galvanized steel drum; each drum is 200kg in net weight; if necessary, pallet tank, box-type container, or car tank can be used for packing and transportation. During storage and transportation, it is necessary to pay attention to ventilation, coolness, and dryness, avoid sunlight and rain, and keep away from water and heat source. Storage in temperature of over 60℃ for a long time will cause negative impact on product quality. Short term of temperature rise or drop will not cause great impact on product quality. This product is non-flammable and explosive product.
