Cold Chain Logistics

Keep food safely chilled!

The booming development of cold chain logistic industry shows the trend

of standardization, modularization and factory cold storage construction.

Moisture preservation cold storage, air conditioning warehouse, Mini energy-saving cold

storage group shows its economy, energy saving, high automation and strong adaptability.

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
