Rubber and plastic thermal insulation
Rubber and plastic thermal insulation
This rubber and plastic thermal insulation material is a closed-cell elastic material with excellent properties such as softness, flexure resistance, cold resistance, heat resistance, flame retardancy, water resistance, low thermal conductivity, shock absorption and sound insulation. It can be widely used in various cold and hot medium pipelines, containers and facilities in industries and sectors such as central air conditioning, construction, chemical industry, medicine, textile and light industry, metallurgy, shipbuilding, vehicles, electrical appliances and agriculture, which can achieve the effect of reducing cold loss and heat loss. It is convenient for construction and has a neat and beautiful appearance.

General Specification Table for Pipe Products
Note: Items marked in black represent standard stock sizes currently available; red text indicates custom sizes. For details on manufacturing other specifications, please consult the Marketing Department. Sheets are recommended for pipes with an outer diameter exceeding 89mm. If the required thickness of thermal insulation material is over 25mm, multi-layer overlapping installation is advised to achieve the target thickness.
