Silicone sealing strip double-sided self-adhesive sealing strip shock-absorbing silicone strip source manufacturer

Flame-retardant silicone frame is a type of silicone product with flame-retardant properties. By adding flame retardants to silicone, it gains the ability to inhibit flame spread when exposed to fire. Below is a detailed introduction to it:

Characteristics

1.Excellent flame-retardant performance: Usually added with aluminum hydroxide, phosphorus-based flame retardants, etc., it can meet the UL94V-0 flame-retardant standard, producing low smoke and no toxicity when burning.

2.Wide temperature resistance range: The normal operating temperature is -50°C~200°C, and it can withstand high temperatures of 250°C for a short time, adapting to various high-temperature environments.

3.Good chemical stability: It features anti-aging, ozone resistance and UV resistance, and has good tolerance to acids, alkalis and organic solvents.

4.Superior insulation and sealing performance: It maintains high insulation with a high volume resistivity, and also has excellent compression resilience, making it suitable for sealing and waterproofing applications.

Application Fields

1.New energy vehicle sector: It is commonly used in power battery packs. For example, the aerogel thermal insulation cell insert developed by Shanghai Chunsil New Material Technology Co., Ltd. is made of ultra-thin aerogel felt combined with a high-temperature resistant flame-retardant silicone frame and composite flame-retardant PET film, which can effectively isolate heat spread to surrounding battery cells.

2.Electronics and electrical appliances sector: It can be used as a flame-retardant insulating gasket for circuit boards to absorb mechanical vibration, and also for sealing, waterproofing and heat dissipation assistance in charging piles, 5G equipment and other devices.

3.Construction and transportation sectors: It is applicable as a sealing strip for fire doors and windows, fireproof filling for cable channels, and sound insulation and shock absorption material for rail transit carriages, etc.

The buffer thermal insulation core consists of a thermal insulation material layer and a silicone foam frame surrounding its four sides. The silicone foam frame reaches the UL94V-0 flame-retardant grade, featuring both excellent buffering performance and superior thermal insulation performance.
