1, Core Features of Closed cell silicone sponge sheet
(1) The pores are independently sealed, with outstanding waterproof and moisture-proof performance, which can block the penetration of water vapor.
(2) Low thermal conductivity, significant insulation effect, suitable for high temperature environments (temperature resistance up to 250 ℃ or above).
(3) Soft and elastic, strong resistance to bending, able to withstand repeated compression deformation.
(4) High strength and wear resistance, not easily deformed after long-term use.
(5) Acid and alkali resistant, oil resistant, aging resistant, suitable for corrosive environments.
(6) Non toxic and environmentally friendly, in compliance with food grade and medical grade material standards.

 

2, Main Application Areas of Closed cell silicone sponge sheet
(1) Sealing and shock absorption: used for sealing car windshields, mechanical components, and buffering electronic components.
(2) Precision equipment: seismic protection layer for medical devices and instruments.
(3) Sound insulation and heat insulation: Sound insulation filling materials for walls and pipelines to reduce noise and heat conduction.
(4) Waterproof engineering: anti-seepage filling for water conservancy engineering and underground facilities
(5) High temperature environment: oil refineries, high-temperature furnaces, and insulation layers for tire production equipment.

 

3, Production process and technology
Using secondary foaming method or radiation cross-linking technology, control the uniformity and density of foam pores (0.3~1.1g/cm ³).
High temperature foaming molding (162-168 ℃) ensures stable material structure.
It can be die cut and divided into sheets, rolls, or shaped parts to meet different size requirements.
The surface can be covered with adhesive or aluminum foil to enhance adhesion and weather resistance

 

4, Industry adaptation cases
(1) Hot pressing of new energy vehicle batteries: As a thermal insulation layer for battery modules, Closed cell silicone sponge sheet blocks thermal runaway conduction of battery cells and reduces component weight (density 0.3-0.9 g/cm ³ ).
(2) Copper clad laminate production: In the PCB substrate lamination process, the silicon sponge board uniformly transfers pressure and absorbs thermal expansion stress, reducing board warping.
(3) Composite material molding: used for hot pressing and curing of carbon fiber/glass fiber prepreg, its low thermal conductivity can delay the resin curing speed and improve molding uniformity
