Product Overview

Description

 

Polyurethane Systems for Air Filter

DLQ-A / DLQ-B

Product introduction

A component of Polyurethane systems of air filter (DLQ-A)is composed of hyperactive polyether polyols, cross linking agent, compound catalyst and so on.  B component (DLQ-B)is 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 it is widely used for manufacturing cars, ships, construction machinery, generator set and other internal combustion machinery's air filter cores etc.
