HT800 Silicone Rubber
HT800 Silicone Rubber
Advanced Seals and Gaskets Ltd pride themselves on being one of the UK’s largest suppliers of non-metallic materials including foams, sponges, rubber, plastics and specialist papers.
One such material is HT800 Silicone sponge, which is a medium firmness sponge with flame retardant properties, which is manufactured at 915mm wide, and in standard thicknesses ranging from 0.8mm - 12.7mm, at various roll lengths depending on the thickness.
ASG has extensive on-site conversion facilities comprising of various splitters, presses, bandsaws, slitters, coaters and CNC machines, which we can convert HT800 silicone sponge into a whole host of bespoke parts including cut sheets from 1 meter in length to gaskets, washers, pads or strips, coated in a range of self-adhesive and foils.
What is HT800 Silicone Sponge?
HT800 is a closed-cell, lightweight, versatile, medium firmness, flame retardant silicone sponge, (also called HT800 silicone sponge) that offers enhanced sealing capabilities and is used in applications where fire safety is a concern as the material will offer low levels of flame propagation, low smoke generation and low emission of toxic gases. The closed-cell structure of the HT800 silicone sponge means it can be used in sealing applications against dust, moisture and air.

Advantages of using HT800 Silicone Sponge
There are many advantages to using HT800 Silicone sponge such as the highly efficient sealing capabilities, its resistance to UV, Ozone, extreme temperatures and fire, which makes it suitable for a range of uses both indoors and out.
HT800 silicone is found widely used for applications such as outdoor sealing where it protects against the penetration of air, dust, moisture such as in lighting fixtures, air conditioning units, electrical cabinets and other outdoor enclosures.
Due to its compression set, HT800 is also well suited for use in shock absorbing and vibration isolation applications. HT-800 demonstrates excellent memory and low-stress relaxation, which in turn reduces costs from seal or gasket failure caused by poor compression set and softening.. The material can also be used as shock reduction and vibration isolation in a range of electronics and transportation applications.
Different Grades of Silicone Sponge Available
High-Temperature Sponge is a medium density silicone spine that is soft and pliable, used in a range of sealing and gasketing applications where a temperature range of -60°C to +270°C (300°C intermittently) is required.
Fluorosilicone Sponge is a blue, closed-cell material that is resistant to oil, harsh chemicals, fuels and solvents. It has an impressive operating temperature range of -62°C to +204°C, a low compression set and electrical strength
Thermally Conductive Silicone is a closed cell sponge that offers thermal conductivity and electrical isolation properties, found used in applications where a thermal transfer is required.
High Recovery Silicone Sponge is manufactured with a fine fabric finish on both sides, in a choice of red oxide or black colours This closed cell sponge is popular with clothing and fabric printers because of its density and easy release properties.
FDA Sponge is a medium density, closed-cell silicone, white in colour. This particular grade of silicone sponge is platinum cured to conform to FDA 177.2600 and EC 1935/2004 standards for use as gasketing and sealing in food, drink and pharmaceutical applications.
