China Kingflex Thermal Insulation Rubber Foam Sheet Manufacturers, Supplier
Kingflex Thermal Insulation Rubber Foam Sheet is a kind of black flexible elastomeric nitrile rubber foam. It is original closed cell and fiber-free elastomeric foam.
The expanded closed-cell structure makes it an efficient insulation. It is manufactured without the use of CFC's, HFC's or HCFC's. Thermal Insulation Rubber Foam Sheet is also effective for reducing HVAC noise. On cold systems, insulation thicknesses have been calculated to control condensation on the insulation outer surface, as shown in the table of thickness recommendation.

The Manufacturing Process of Thermal Insulation Rubber Foam Sheet
The three main components used in the manufacturing of elastomeric closed cell foam insulation include the following:
These components are combined in a large mixer, typically in batches of 500 pounds or more. The mixture is then put through extruding equipment to form a particular profile or shape, typically either a round tube or a flat sheet. The profile is heated in an oven to a specific temperature, a process that causes the chemical foaming agent to change from a solid to a gas. When this occurs, thousands of tiny air pockets (cells)—all of which are connected—form. The profile is carefully cooled to ensure that these cells remain unbroken and intact, maintaining the material’s closed cell structure. It is then cut to size and packaged for shipment. Elastomeric foams are made without the use of chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), or hydrofluorocarbons (HFCs), making them suitable for the toughest environmental specifications.
Frequently Asked Questions (FAQ)
What makes this thermal insulation sheet highly efficient?
The expanded closed-cell structure is designed to deliver superior insulation efficiency. It is also calculated to effectively control condensation on the outer surface of cold HVAC systems.
Does the manufacturing process use environmentally harmful gases?
No. The Thermal Insulation Rubber Foam Sheet is manufactured completely without the use of CFCs, HFCs, or HCFCs, ensuring compliance with strict environmental regulations.
Can this material assist with noise reduction?
Yes. In addition to thermal insulation, the foam sheet provides excellent sound attenuation, making it highly effective at blocking HVAC noises and dampening structure-borne vibrations.
What is the safe operating temperature range for this insulation?
According to the technical testing standard GB/T 17794-1999, the insulation sheet operates safely within a temperature range of -50°C to 110°C.
What fire safety certifications does this product hold?
The material holds Class 0 and Class 1 fire ratings under BS 476 Part 6 & 7 testing standards, and scores a Flame Spread and Smoke Developed Index of 25/50 under ASTM E 84.
What raw materials are used to make elastomeric closed-cell foam?
It is manufactured using three main components: a synthetic rubber blend (such as NBR and/or EPDM), Polyvinyl chloride (PVC), and a chemical foaming agent that expands into closed-cell air pockets during heating.
