RESEARCH AND DEVELOPMENT NEWS - Electron Beam Irradiation Technology for Thin Rubber Products

Working principle

Basic Principle Is The Same As A TV. Accelerators work on the same principle as a television tube. Electrons are generated by a heated filament, which forms the electron gun. A voltage gradient draws the electrons away from the gun and accelerates them through the vacuum tube. As the high voltage beam of electrons passes from the beam tube and through the scan magnet, an oscillating magnetic field sweeps the beam back and forth across the scan window.

Advantages

Cables, Heat Shrink Tubes, PE Foams etc, are subjected to E-Beam Radiation with extreme advantages compared to other cross-linking system. Cross-linking of O Rings, K-Rings, Gaskets, Diaphragms, Seals revealed extremely positive results compared to the conventional curing system.

The Comparison Table

E-Beam Radiation Curing System

Conventional – Sulphur / Peroxide Curing System

Direct Cross-linking by C-C linkage by electron beams

Cross-linking by C – S x – C linkage (x = 1,2,3….) or C – O x – C linkage (x = 1,2,3….)

Extremely Strong Bonds

Comparatively weaker bonds

Zero blooming effects

Sulphur/Oxide have chance to bloom to periphery leading to surface deterioration

Extremely High Tensile Strength

Lower Tensile Strength

Extremely high resistance to Compression Set

Lower resistance to Compression Set

Extremely high resistance to Oils, Grease, Lubricants

Lower resistance to Oils, Grease, Lubricants

Highly improved Accelerated Ageing properties

Lower accelerated ageing properties compared to E-Beam system.

Lower material waste

Higher Material Waste

Extremely short curing cycles

Comparably curing time is quiet high

Very high productivity

Lower productivity

Perfect for thin products

Good for bigger products

Reason for Improvement

  • High Degree of Cross-Linking
  • No Polymer degradation due to high temperature as EB Cross-linking occurs at room temperature
  • No Oxidative degradation in polymers as observed in chemical cross-linking
