Product Description

High Resilience Blend Polyols

DHR-AB

 

 

Introduction

DHR-A blend polyols (Part A) adopts all water technology, it consists of hyperactivity polyether polyol and POP, crossing linking agent, foaming agent, flame retardant and compound catalyst etc. It reacts with isocyanate DHR-B(compound B), adopting cold moulding technology HR cold curing polyurethane foam, which has good mechanism(high resilence, low lag loss) ane high compress and load ratio(sag factor). So it has excellent comfortable for seating touch, good anti-fatigue property, feel as latex surface,nice air permeability and flame retardant performance. At the same time, high productivity, low power, which widely applies to autocar, autobike, train, airplane, furniture etc., which applies to saddles, backrests, mattresses and pillow etc.
