The primary characteristic of these polymers is elasticity. The following characteristics, taken collectively, can be used to describe the usual elasticity of rubber (vulcanized):
- Modul with a low starting stiffness
- High tensile strength, high elongation, and fracture under traction or shear
- Large deformations recover quickly and completely, even if they persist for a long time.
- A broad temperature range across which these qualities persist
While there are additional techniques, such as amines, silanes, anilines, and others, sulphur and peroxides currently perform the two types of crosslinking reactions that are most frequently used (by volume) in the industry.
Crosslinking of sulphur
It consists of the chemical union of sulphur atoms through bonds, which takes place in the presence of heat and pressure.
Crosslinking with peroxide
It entails employing organic peroxides to bind the polymer chains along the carbon atom chemically.
These materials exhibit higher ageing resistance at high temperatures and suffer from less compression deformation.
