Polyurethane Systems for Air Filter

DLQ-A/ DLQ-B

Product introduction

A component of Polyurethane systems of air filter DLQ-Ais composed of hyperactive polyether polyols, cross linking agent, compound catalyst and so on.  B component DLQ-Bis modified isocyanate, and it is micro-pore elastomer which adopts cold molding.  It has excellent mechanical and anti-fatigue property.  Also,with short production cycle, high efficiency and low energy consumption.  So
