Tdi and Mdi Type High Resilience Flexible Polyurethane Raw Materials Polyether Polyol for mattress

Product Description

Description
LYR-A (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 LYR-B(Part B), adopting cold moulding technology HR to make cold curing polyurethane foam, which has good mechanism(high resilence, low lag loss) and 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 with high productivity, low power, which widely applies to autocar, autobicycle, train, airplane, furniture etc., which applies to saddles, backrest, mattresses and pillow etc.
