HT800 Sheet
HT800 Sheet
Here at Advanced Seals and Gaskets Ltd, we offer a vast catalogue of sheet materials, including a range of silicone sponges, in various densities and grades. 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 which can be cut down into HT800 silicone sponge sheets at one meter or two-meter lengths as, or cut down to bespoke sizes and pads.
Our on-site laminating service not only allows us to laminate layers of sponge together to create greater depths but also enables us to supply them coated with a choice of self-adhesives, foils or even laminated to other materials.
HT800 silicone sponge sheets are a popular product as they give the customer the flexibility to be able to cut their own parts such as strips, gaskets or pads out as and when required or to cover larger surfaces reducing the need for joins in the material.
What are HT800 Silicone Sponge Sheets?
HT800 is a closed-cell, lightweight, versatile, medium firmness, flame retardant silicone sponge sheets 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.
HT800 silicone sponge is one of ASG’s popular materials, held in roll form in a range of thicknesses starting from as little as 0.8mm ensuring HT800 silicone sponge sheets can be cut and despatched within a minimum timeframe.
Rolls of HT800 silicone sponge are sometimes also taken by customers as they have the freedom to cut their own HT800 silicone sponge sheets in various sizes as and when they are required, which can also be manufactured and supplied with a choice of finishes including foils and self-adhesives.

Advantages of using HT800 Silicone Sponge Sheet
HT800 sponge sheets and products cut from them are often used to fill gaps and irregularities between two surfaces and to provide a solution to unwanted rattles, noise, vibrations, to seal against air, gas, dust and liquids, and can also be used to cushion between moving pads to reduce friction and damage to equipment.
Other advantages of using HT800 Silicone sponge sheets include 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 sheets and components cut from them are 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 silicone sponge sheets are also well suited for use in shock absorbing and vibration isolation in a range of electronics and transportation 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.
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, 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.
