Plate structure, with nitrile butadiene rubber as the main raw material by foaming, with completely closed foam flexible rubber plastic insulation material.

Test method: flame extension range ≤165mm when 1.5 minutes, flame extension range ≤165mm when 10 minutes.

Introduction

Mainly NBR/PVC as the main raw material, cooperate with flame retardant agent, foaming agent, curing agent, promoter and stabilizer, strengthening agent, such as additives, end spacing, mixing, extrusion, curing, foaming, cooling, cutting and become, has a small independent closed pore structure, heat preservation performance is good, good compression resilience, strong ability to resist water vapor permeability, good fireproof performance, low smoke non-toxic, Safe and reliable, long service life.

Application

It is widely used for thermal insulation and cold protection of various pipes and equipment in the high-end market of HVAC system to fully ensure the energy-saving effect of reducing cold and heat loss. It is widely used in various public places, industrial plants, clean rooms and medical and educational institutions.
