ADVANTAGE
Polyurethane is a high performance insulation material renowned for its light weight, high compressive strength and mature industrial production technology. It also has the characteristics of shockproof, electrical insulation, heat resistance, cold resistance, solvent resistance and so on. In cold storage application, polyurethane foam effectively reduces the wall insulation thickness, suitable for many codl storage room application such as wall, roof and basement.
PROCESS
Continuous,non continuous panel production, and on-site spray
TECHNOLOGY
Rich experience and mature industrial production technology
Application
GB standard
GB/T 50404-2017 Technical Code for Regid Polyurethane Foam Insulation and Waterproof Engineering
