Polyether polyol 330N
Description
Polyether 330N is a highly reactive polyether with high reactivity. It can react with an appropriate amount of isocyanate to produce polyurethane reaction injection molding (RIM) products. The cold cured high rebound products prepared with it, such as car cushions, seat cushions for transportation vehicles, steering wheels, instrument panels, handles, and other automotive interior decoration and furniture, have excellent resilience, compressibility, and comfort.

Usage
Polyether polyol 330N is a high molecular weight, highly active polyether commonly used in high resilience foaming processes, RIM processes, and POP mixing, equivalent to DOW4701. The polyurethane soft foam can be produced by combining with the polymer polyol. The performance is comparable to imported V-4701 and domestic JH-820, ZS-1808, and SPC-350 polyethers.
