China Low Thermal Rubber Foam Insulation Pipe Manufacturers, Quotes

Product Description

Closed Cell Foam Tube Insulation, using rubber as the main raw material, contains no fiber, no formaldehyde, and no CFCs or other ozone-depleting refrigerants. It can be directly exposed to the air without harming human health. The standard product is black and is divided into two major categories: rubber foam insulation sheets and insulation pipes. These are widely applied in central air-conditioning system water pipelines, ducts, hot and cold water pipelines, mine pipeline systems, refrigeration systems, and HVAC systems.
