THE ENDLESS POSSIBILITIES OF RUBBER
Synthetic cis-polyisoprene (IR)
|The rubber:||Is basically the same polymer as natural rubber – but made synthetically.|
|Resistance and properties:|
Synthetic cis-polyisoprene has a high tear, pull and abrasion resistance. The aging properties of this synthetic alternative are better in comparison to natural rubber and also the machine-ability of cis-polyisoprene is better. Temperature resistance is also considerably better in comparison to natural rubber.
Despite the synthetic composition, this rubber is mechanically weaker in comparison to natural rubber, because it is not 1--% the cis-isomer. The ageing and weather properties are poor. Cis-polyisoprene also has poor resistance to mineral oils.
This rubber is used in the tyre industry and shock isolators.
