Foamed polyethylene

Foamed rubber consists of foamed synthetic rubber with a self-adhesive layer applied to one side (a water-dispersed acrylic emulsion based on silicone with a high degree of adhesion).The foam synthetic rubber material is used to insulate rigid air ducts, large diameter pipes, containers in places where additional mechanical protection, weather protection and enhanced thermal insulation are needed.

Features

Foam rubber is resistant to aggressive environments and provides tightness against condensation. The pipeline is reliably protected and will last up to 10 times longer; The temperature in the pipe remains unchanged. Microporous rubber practically does not conduct heat, its index is 0.036 W/(m* K).

Composition

Foamed rubber is made from natural and mostly combined rubber, EVA, styrene. Requirements for rubber: 1) The rubber should be sufficiently plastic, the rubber mixture should be evenly crumbly.
