Silicone Products

Supergum manufactures high-heat silicone rubber (HTV, HCR) and liquid silicone rubber (LSR), in cutting-edge processes like extrusion and molding. We manufacture tubes, profiles and molded parts in advanced manufacturing techniques.
Silicone is a soft, elastic and durable, Long service life material, total weather resistance, and working in a wide temperature range from -40 OC to 220 OC. The basic silicon types are customizable to the user and customer requirements.


We have special silicone types that can provide the following unique features:

  • Resistance to temperatures of +260 OC or cold of -125 OC
  • Has very low friction coefficient, or can perform self-lubrication.
  • Extremely low hardness, as low as 0 Shore A.
  • High transparency for light transmission.
    Very high elongation 1100%
  • With a low or high modulus
    Resistant to specific chemicals
  • Can be physiologically safe, hypoallergenic
  • Grades of medical use
  • Electrical conductivity, thermal conductivity and fire resistance

Additional special types according to specific requirement.

Most types of silicone are approved for use with approved food USA:

FDA21 CFR §177.2600 or BfR (Former BgVV)
Silicone is also available in sponge for low compression applications.

Our team of development engineers with 30 years of experience in the development and manufacture of silicone products and with control of the most advanced production technologies, and at the disposal of the customers for support and development of silicon products.

Silicone O-Ring & Washers

Silicone O-Ring

O-ring is mainly used in fluid static application (For example, water, oil, air, chemicals solvent, chemicals, etc. ) . In General, the temperature range is from -60 ℃ up to +220 ℃. Silicone rings are considered very elastic and soft and have a very long working life. The orings supplied as Parker size standards, milimetric or specials.

Silicone bonded seal

silicone gaskets are provided as a closed ring and are made of extrusion profile (extrusion) followed by gluing or gluing to a ring-shaped closure. In this way, large gaskets are obtained without the need for large molds and heavy production costs as is usually required for such large products.

Silicone rubber inflatable seal

Supergum supply Inflatable (Gaskets) seals, which are made from high strength FDA Approved Transparent Silicon Rubber and comply to class 21 CRF 177.2600.


Our seals provide on inflatable sealing solution, for oven Door Seals and sterilizer


When air pressure is applied, the seal either expands or raised up to meet the sealing face.


  • It provides a Leak Proof closure, yet allows clearance when needed.


  • It minimizes the need of close matching and fabricating tolerance.

Silicone Rubber Sheets

Supergun manufacture cut gaskets, from gasket sheets. The gaskets are according to customer’s spec Die cut is made by special die CNC cutting: we have a CNC cutting machine, with a special head for cutting elastomeric material The CNC works with 2D file, the results are very accurate.
