At R4 Gaskets, we offer BISCO® flame retardant silicone sponge gaskets that provide superior flame-retardant properties compared to other silicone sponge grades. Available in thicknesses from 0.8mm to 25.4mm depending on density, these gaskets are ideal for a variety of applications where safety and performance are paramount.

Key Features and Benefits

  • Flame Retardancy: These gaskets offer exceptional flame-retardant properties, ensuring enhanced safety for a wide range of applications.
  • Versatility: Combining the softness and flexibility of sponge with the sealing and resistance properties of rubber, BISCO® flame retardant silicone sponge is highly versatile and suitable for numerous uses.
  • Ease of Use: Easy to cut and shape, this silicone sponge also features excellent shape memory, maintaining its form even after extended periods of use.

Available Densities

Choose from five standard densities to match your specific needs:

  • HT-800 – Medium
  • HT-820 – Firm
  • HT-840 – Extra Firm
  • BF-1000 – Extra Soft
  • BF-2000 – Ultra Soft

Understanding Densities

HT-800 (Medium)

This medium-grade silicone sponge features excellent shape memory and low stress relaxation, making it ideal for gasket manufacturing. Its cell structure prevents air and water penetration and offers good UV, ozone, and temperature resistance.

HT-820 (Firm)

Offering higher tear resistance and superior tensile strength, this medium-firm grade provides excellent durability and sealing properties. It resists UV, ozone, and extreme temperatures, and its cell structure prevents fine particles and liquids from penetrating.

HT-840 (Extra Firm)

Ideal for press pads, this extra-firm grade offers superior conformability and even pressure distribution at high temperatures. Its cell structure prevents fine particles and water penetration, and it resists weathering, UV, and ozone damage.

BF-1000 (Extra Soft)

Utilising an open cell structure, this extra-soft grade compresses to protect against dust, moisture, and air penetration. It requires less force to seal enclosures and is perfect for outdoor applications and electronics protection. It also offers good resistance to weathering, UV, and ozone.

BF-2000 (Ultra Soft)

The ultra-soft grade offers high compressibility, allowing it to conform to awkward shapes and variable-width gaps. With excellent shape memory and low stress relaxation, it performs well over long periods. Its closed cell structure significantly reduces gas and liquid penetration, and it resists weathering, UV, and ozone damage.

Applications

  • Electronics: Ideal for protecting against shock and heat, providing reliable sealing for outdoor enclosures.
  • Industrial: Suitable for machinery and equipment requiring durable, flame-retardant gaskets.
  • Automotive: Perfect for applications needing superior resistance to extreme conditions and harsh environments.
