Flame-resisting grade polyether polyol
I. Product brief-introduction
YB-3082 is polymer polyol specially used for flame-resisting polyurethane high spring foam. The polyurethane foam plastic composed by taking it as base not only has higher carrying capacity and good spring performance, but also improves the foam hole structure of foam and the physical & mechanical performances. Especially, it has excellent flame-resisting performance: oxygen index ≥28%, low mist density, meets with the National Fire-control Standard and the British BS-5852 Standard. It can be easily used to make up different kinds of compounding stuff.
Density of foam product can be adjusted according to the customer’s requirement, normally, it can be controlled at range of 40-70kg/m3 for module, 30-45 kg/m2 for block.
