The Benefits of Radiation Chemistry

The Raychem Corporation acquired by Tyco Electronics in 2000 pioneered the development of heat-shrinkable products.

Raychem were responsible for the creation of new types of improved plastics and elastomeric materials which possess unique properties through modification of the raw material by the application of radiation technology. These raw materials are engendered with characterists which go far and beyond the normal physical limits of untreated plastics.  These changes are achieved by subjecting the base plastics and elastomers to high energy electron beam radiation.

Typical advantages derived from this technology include:

  • High Flexibility
  • Flame Resistance
  • High Dielectric Strength
  • Cold Flow Resistance
  • High Temperature Stability
  • High Mechanical Strength
  • Chemical Resistance
  • Abrasion Resistance

The most commonly used product categories for these enhanced wonder plastics are Single Wall Tubing’s Raychem’s RNF 100 and RNF 3000 being the quality standard bearer.

Dual Wall Tubing’s with Atum, HTAT and SCL leading the way in this category, and Elastomeric Tubing’s with Viton and DR25 key products to the aerospace and defence markets.

This technology was originally developed in the 50’s since then these 3 basic product categories have been refined, enhanced and developed. Careful synthesis of materials provided products which could perform selective and very specific purposes. The addition of adhesives, shielding facilities, fibre and fabric materials ensures uses in the most sophisticated installations.

Typical uses include:

  • Identification By Colour Coding
  • Strain Relief
  • Primary Electrical Insulation
  • Cable Jacketing and Repair
  • Component Encapsulation
  • Waterproofing
  • Mechanical Protection
  • Corrosion Protection
  • Packaging
  • Environmental Protection
