Do You Know These Characteristics About
Silicone Foam?

Silicone foam is a medium density, silicone rubber closed foam product. The temperature range of the foamed silicone foam material is -60°C-200°C, which can be used for a long time and maintain its soft and elastic properties. It is environmentally friendly, non-toxic, and has excellent electrical properties. Performance and chemical stability, water resistance, ozone resistance, weather resistance, non-corrosive, physiologically inert, non-toxic and tasteless, low linear shrinkage, easy to operate and so on.

The foam materials are: PU foam, anti-static foam, conductive foam, EPE, anti-static EPE, PORON, CR, EVA, bridging PE, SBR, EPDM, etc. Thin, reliable performance and a series of features. Take NBR foam as an example, it is a kind of NBR foam material, its detailed description is as follows: Color: black and white, color; Maximum size: 2000×1000×35; Material description: Open-cell NBR is anti-aging, environmentally friendly, and oil-resistant , Good sound absorption, no toxic gas is produced when burning. Closed cell NBR has small bulk density, good weather resistance, waterproof and vapor proof, oil resistance, and environmental protection. Material application: Open-hole NBR is used as sound absorption, shock absorption, heat preservation, sealing and heat insulation in automobile, air conditioning, electronics, audio and other industries. Closed-cell NBR is used as sealing, sound insulation, shock absorption, and thermal insulation material for automotive, electronics, air conditioning, and other fields.

Silica gel foam should introduce foreign foaming technology, foam evenly, density can reach 0.25-0.85g/cm3, Shore hardness 8-30A. Environmentally friendly, non-toxic, odorless, good resilience, good flexibility, no bubbles and no pores on the surface. The foamed silica gel sheet has high strength, long service life, high temperature resistance up to 300 ℃ and long-term use without deformation. Foamed silica gel board is environmentally friendly, resistant to high and low temperatures, compression resistance, acid and alkali resistance, anti-aging, and UV resistance.
