Silicon compounds «SIEL»

Unique composite silicone materials that are polymerized by the mechanism of poly-coupling or under the influence of UV radiation and are intended for use in medicine, electronics, electrical and radio engineering, fiber optics and optoelectronics, aviation and other industries.

General characteristics:

  • High chemical purity (total impurity content less than 10-3%)
  • Biological inertia and non-toxicity
  • Operating temperature range: from -100оС to +300оС
  • Physical state: gel-like, elastomers, glassy.

Compound for electrical appliances

Compound for electrical appliances are used as elastic sublayers for protection of p-n junctions of semiconductor devices and devices, filling materials for printed circuit boards, blocks and modules, protection of electronic circuits with a high degree of integration, and for other purposes.
