Product Code: VGD10

Overview:

Silicone rubber can be expanded into silicone sponge by using blowing agents. The resulting sponge has a fine non-interconnecting cell structure encapsulated by a soft, smooth, outer skin. Silicone sponge is an excellent sealing medium, due to its stable chemical structure and good recovery.


Note: VGD16 has a thinner skin than other silicone sponge grades. It appears wrinkled/creased. Rejections cannot be accepted on this basis. Sheets supplied will not be completely flat.

General Properties:

  • Minimal water absorption (IP65-66 achievable)
  • Resistance to ultraviolet light and corona is good
  • Resistance to arcing and ozone is good
  • Oxidation is virtually non-existant
  • Excellent for vibration damping and cushioning components
  • Generally resistant to moderate or oxidising chemicals
  • Excellent heat insulation

Product Code: VGD16RL

Overview:

A specialist grade of fire-retardant silicone sponge developed specifically for use in rail and mass transit applications. Key benefits include better sealing performance, lower closure force – enabling lighter and thinner substrates to be used and reduced weight.

Features:

  • Compliant to EN45545-2
  • Compliant to UL94V0
  • Sealing rating to IP67 possible


Temperature Range: -50°C to +180°C (working) Up to 200°C (intermittent)

Density: 220 Kg/m3

Hardness: 55 Shore "00" Approx. 12 Shore A

Elongation at Break: 130%

Tensile Strength: 0.5 MPa

Compression Deflection: 40Kpa

Compression Set: 15%

Fire Rating: UL94 V0*

Limiting Oxygen Index: 42.0

Smoke Density: 26.95

Toxicity: <0.021

 

Density measured on 12mm sample. The density of samples of different sizes will be different from that stated here. Hardness measured on 12mm thick samples. At less than 12mm the measured hardness will increase with density. Shore “A” hardness given as guidance only, as this material is unsuitable for accurate measurement wit Shore A test method. Compression Set values based on 12mm thick samples 22hrs @ 175°C.


*Statement of UL94 VO compliance is based on independent testing. Full test results are available on request.
