Performance Characteristics of Flame-Retardant Silicone Sheets

Performance Characteristics of Flame-Retardant Silicone Sheets

In modern industrial and civil fields, the safety of materials has attracted increasing attention. Especially in industries such as electronics and electrical engineering, transportation, and construction, if materials catch fire and burn, they will not only cause economic losses but also may lead to serious personal injuries. Therefore, polymer materials with excellent flame-retardant properties have become a hot spot in the market. Among them, flame-retardant silicone sheets are being widely used and recognized due to their unique performance advantages.

I. Basic Characteristics of Flame-Retardant Silicone Sheets

Silicone sheets are made of silicone rubber as the matrix, formed by calendering, molding, or extrusion, and then prepared through a high-temperature vulcanization process. Silicone rubber itself is an elastic material with excellent resistance to high and low temperatures and good chemical stability. To meet flame-retardant requirements, adding specific flame retardants (such as aluminum hydroxide, magnesium hydroxide, fumed silica, or halogen-free and environmentally friendly flame-retardant systems) to silicone can significantly improve the material's self-extinguishing ability under open flame or high temperature, slowing down the combustion rate or even making it self-extinguish. In addition, flame-retardant silicone sheets also have the following prominent characteristics:

Strong resistance to high and low temperatures: It can maintain stable performance for a long time in an environment of -110℃ to 350℃.

Good electrical insulation: High dielectric strength, which can effectively prevent electric leakage and short circuits.

Aging and corrosion resistance: Resists erosion from ozone, ultraviolet rays, and various chemical media.

Environmental protection and safety: Halogen-free and non-toxic, with low smoke emission during combustion, complying with international environmental protection regulations.

Flexibility and easy processing: Can be cut, stamped, or molded into various shapes to meet diverse needs.

II. Application Fields of Flame-Retardant Silicone Sheets

With its excellent comprehensive performance, flame-retardant silicone sheets are widely used in multiple industries:

Electrical and electronic equipment: Used as insulating and heat-insulating sheets, electrical control cabinet seals, cable protective sleeves, etc., to improve the safety of electrical systems.

Rail transit and automobile manufacturing: Applied in carriage sealing, engine compartment protection, and interior flame retardancy to ensure the personal safety of passengers.

Construction engineering: Used as fireproof and heat-insulating materials, suitable for door and window sealing, wall protection, and building protective barriers.

Medical and food machinery: Adopting food-grade environmentally friendly flame-retardant formulas, it is used in equipment that requires both flame retardancy and hygiene.

Aerospace and military industry: Undertakes multiple tasks such as fire prevention, insulation, and sealing in high-end equipment.

III. Industrial Value of Flame-Retardant Silicone Sheets

Against the global background of advocating "safety, environmental protection, and energy conservation", the value of flame-retardant silicone sheets is particularly prominent:

Improving safety: Reducing fire risks and lowering accident losses.

Complying with environmental trends: Adopting halogen-free and environmentally friendly formulas to meet international environmental requirements such as RoHS and REACH.

Extending equipment service life: Its weather resistance and chemical resistance ensure the long-term stable operation of equipment in harsh environments.

Reducing usage costs: Flame-retardant silicone sheets can be reused with low maintenance costs.

Flame-retardant silicone sheets, with their excellent flame retardancy, weather resistance, and environmental friendliness, continue to expand their applications in industrial and civil fields. Their emergence not only improves the safety level of products and equipment but also provides a strong guarantee for building a safer and more reliable production and living environment.
