Sponge Rubbers

Sponge Rubbers are the foremost material that are used for seals & gaskets for preventing leaks of gasses or fluids at low compression forces.

Properties include:

• softness
• elasticity
• very low compression set
• sealing
• sound and thermal insulation
• shock absorbent
• anti-vibration
• fire-resistant
• electrically conductive

Neoprene

Neoprene is a trade name of Dupont for a rubber called Polychloroprene.

In the foamed format, it has an excellent characteristic for creating a seal or gasket upon the application of a small amount of compression. Uses include: Oil Seals WeatherStripping Vent and Air Conditioning Seals.

• Good Heat Resistance -20 to + 100°C
• Moderate chemical & oil resistance
• Good sea water, acids/alkalis, fats & grease, oil/ fuel resistance
• Good Ozone & UV resistance
• Excellent Fire Retardant capabilities. FMVSS302, UL94 HF1, V0

The foams can be supplied with or without a self adhesive backing and can be cut into coils for sealing tapes.

EPDM

Used in many outdoor applications such as weatherstrips, mouse mats, light seals, vibration dampening, mounting tapes.

• Excellent Acid/Alkali & steam resistance
• Good abrasion, weathering & ozone resistance
• Poor oil & solvent resistance
• - 50°C to + 120°C continuous
• + 140°C intermittent
• FR to UL94, FMVSS 302

Available in a Supersoft version for low compression seals.

The foams can be supplied with or without a self adhesive backing and can be cut into coils for sealing tapes.

PVC/Nitrile

• excellent resistance to acid, fuel & oil,
• ozone resistant
• performs well in applications where temperatures can range from -40 to +70°C.

Uses include: Oil Seals, Cushioning, Vibration Dampening Shock Absorption

Neoprene / EPDM Blends

A formulation of foams where the benefits of both base sponges can be utilised. An example is an oil resistant seal with a high temperature performance. Available in a variety of blend ratios.
