Technical characteristics of silicone LSR

Silicone is a material with an unique combination of properties. It is highly resistant to atmospheric agents, it features excellent electrical properties, it is resistant to high temperatures, it has a good flexibility at low temperatures and a good processability.

The product is made from the molecular structure SI–O–SI–O, which gives its typical stability and low reactivity.

Typical properties of silicone
  • Hardness between 20 – 75 shore/ A
  • Tensile strength 6 – 10 Mpa
  • Elongation 400 – 800%
  • Tear strength 25 - 50 Kn/M
  • Compression set resistance 15 – 25% (22h @ 175°C)
  • Used temperature between -60°C to +250°C
  • Volume resistance 10 Ω cm at 1 x 10 (to the 16th) Ω cm
  • High transparency
  • Odourless and tasteless
  • In line with the European Standards with continuous contact with food
  • Easy to colour
Electrical properties
  • Excellent dielectric strength
  • Typical values between 25 – 35 kV/mm
  • Excellent as a resistance (4.5 kV)
  • Can act as an insulator or conductor
Resistant to atmospheric agents

The bond, silicone-carbon, makes it very resistant to atmospheric agents.
Not sensitive to the UV radiation effects.
Highly hydrophobic.
