foam insulation sheet Advantages

High elasticity and good softness

The internal bubbles are uniform, maintaining good elasticity and softness, and can easily solve irregular pipes

High density load-bearing

High resilience, strong toughness, and not easy to deform, making it ideal for foam insulation sheet applications

Waterproof and moisture-proof

The sound insulation rubber sheet features a closed-cell foam structure, providing a waterproof surface and non-absorbent properties

Moisture-proof and waterproof, long life

High-density closed-cell foam, foam rubber insulation is waterproof and moisture-proof, offering excellent protection against the elements

Fireproof and flame retardant

It burns and carbonizes, does not contain plastic, and goes out immediately when away from fire, meeting national standard B level.

B1 level fireproof, extinguishes when away from fire

The sheet of rubber is designed with a flame retardant level that reaches B1 level to ensure product safety

Thick and dense

Made of nitrile rubber as the main material, it is foamed. The closed-cell foam structure is blocked by bubbles and is difficult to enter, achieving the effect of heat insulation

Good heat insulation effect

Thickened high-density process, heat insulation, high-density material does not deform for a long time Closed-cell foaming technology

Material Introduction

Rubber-plastic insulation board is a soft heat-insulating and energy-saving material made of rubber and polyvinyl chloride (NBR/PVC) as the main raw materials, with various auxiliary materials, and foamed by special process.

The raw material rubber of this material is a flexible material, so the rubber-plastic insulation board also has good elasticity and flexibility. And this material also has many excellent properties.

Low thermal conductivity,

so it has good heat preservation and cold insulation effect, is the nemesis of cold insulation, heat insulation and anti-condensation, and has an isolation effect on many media

Good fire resistance.

Rubber-plastic insulation board, especially rubber-plastic insulation board above b1 grade, is a fire-retardant insulation material after testing by relevant testing standards, which can play a certain blocking role in resisting fire.

Good waterproof and moisture-proof effect

Rubber-plastic insulation board is a closed-cell structure foamed at high temperature. It is difficult for water in the outside air to penetrate into the material. It has good resistance to water vapor penetration, so there is no need to add a vapor barrier outside the cold insulation layer. This material is both an insulation layer and a vapor barrier, and no additional protective layer is required.

Long service life

Because this material is resistant to high and low temperatures, acid and alkali, corrosion, UV, and water vapor, the service life of this material is naturally long, generally more than 10 years.

Smooth and beautiful appearance.

Whether it is installed in a flat place or in some curved and irregular places, it can remain intact and beautiful. It is simple and convenient to install. Because this material with rubber as the main raw material has a certain degree of bending resistance, it can be twisted at will during installation, so it is very convenient to install.
