Product Description

Polyurethane System for Air Filter

DLQ-A/ DLQ-B 

Product introduction

Component  A of polyurethane system for air filter (DLQ-A)is composed of hyperactive polyether polyols, cross linking agent,compound catalyst and so on.  Component B(DLQ-B)is modified isocyanate, and it is micro-pore elastomer which adopts cold molding.  Iexcelt has lent mechanical and anti-fatigue property.  Also, with short  production cycle,high efficiency and low energy consumption .  So it is widely applied to manufacture air filter cores of cars, ships, construction machinery, generator and other internal combustion machinery's .
