HT800 Pads
Advanced Seals and Gaskets Ltd pride themselves on being able to work with a multitude of reputable material manufacturers and suppliers, enabling us to offer pads cut using a range of high-quality silicone sponges. 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 from which HT800 silicone sponge pads can be cut.
Our HT800 silicone sponge pads are produced on-site using drawings or measurements provided by our customers, with whom we work closely to ensure the final product is to their exact specification. Depending upon the size and quantity of pads required, one of many presses, bandsaws or CNC machines can be used to manufacture the final product, from one-off samples to multiple batches runs, which can be supplied as loosely cut parts, or kiss-cut on rolls where a high quantity is required or for use on fast-paced assembly lines.
Our HT800 silicone sponge Pads can be supplied in a plain finish, laminated in layers to create other thicknesses, laminated to other materials or coated with a choice of self-adhesives and foils prior to the gaskets being cut.
What are HT800 Silicone Sponge Pads?
HT800 is a closed-cell, lightweight, versatile, medium firmness, flame retardant 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 sponge means it can be used in sealing applications against dust, moisture and air therefore a great choice for the production of pads. HT800 silicone sponge pads are cut from rolls or sheets of material and are often utilised in the same way as a gasket, whereby they are used to create a seal between uneven surfaces and fill irregularities.
Our HT800 pads can be produced as squares or rectangles with the option of radius corners, and also as circular or oval-shaped pads or ‘discs’, in a range of thicknesses. Manufacturing pads in-house even means we can supply them in a plain or self-adhesive backed finish and even laminate multiple types of material together to create bespoke and unique variations.

Why use HT800 Silicone Sponge Pads?
HT800 Silicone sponge pads offer many desirable properties with many of our customers choosing this grade of silicone as it has all the properties of standard silicone sponge but is flame-retardant and FDA approved. HT800 silicone sponge pads offer excellent heat resistance and are resistant to UV light, ozone and most moderate chemicals.
HT800 silicone sponge can be taken as complete sheets or rolls, or as pre-cut pads which can be used to seal against the intrusion of dust, moisture and air in HVAC, electrical enclosures or lighting systems or as shock and vibration cushioning in transport.
Benefits of using HT800 Silicone Sponge
- Lightweight, durable and versatile material
- Excellent memory, how stress relation and good compression set
- Closed-cell structure creates an excellent seal
- UV, Ozone and Flame resistant
- Meets flame and smoke toxicity ratings and the highest UL, railway, and aerospace standards (BS6853 Cat 1A approved for use in rail vehicles and is LUL (London Underground) approved for use on the London Underground network)
- Easily converted into a range of products, including HT800 silicone sponge pads
Advantages of using HT800 Silicone Sponge Pads
There are many advantages to using HT800 Silicone sponge to manufacture pads, 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 pads can be 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 pads are also well suited for use in shock absorbing and vibration isolation applications, they demonstrate 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 in pad form for 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.
