WHAT IS SILICONE

Technical Characteristics
of LSR Silicone

Silicone is a material with a unique combination of physical properties. It has high resistance to weather conditions, excellent electrical properties, resistance to high temperatures, outstanding flexibility at low temperatures, and excellent processability.
It is a product designed with the molecular structure Si-O-Si-O, which gives silicone inert stability and low reactivity.

Electrical properties

Excellent dielectric strength
Typical values 25-35 kV/mm
Excellent arc resistance (4.5 kV)
Can be insulating or conductive

Resistance to weathering

The silicon-carbon bond gives silicones a very high resistance to weathering.
It is not sensitive to the effect of UV radiation.
It resists hydrophobicity over a long period.
