Explain why butyl rubber is more resistant to oxidation and aging than other elastomers, such as natural rubber
Ding Ji rubber (abbreviation: IIR English Name: Isobutylene-isoprene Rubber)Ding Ji rubber is an elastomer made from a small amount of isoprene (butadiene) copolymerized with isobutene with a high degree of saturation. Generally do not need refined refining, pay attention not toBlends with unsaturated rubber with low degree of unsaturation. Use super accelerators and less sulfur or cure with resin. Due to the slow vulcanization rate of ordinary butyl rubber and high unsaturated rubberIts poor compatibility, self adhesion and co adhesion were not good, and then it was modified by halogenation, which improved its curing rate and compatibility with other high unsaturated rubber
The macromolecular structure unit of natural rubber is isoprene, and the macromolecular chain is mainly composed of CIS -1, 4 polyisoprene. NR is the mechanical and processability comprehensive properties of all rubbers
Usually smoked rubber, crepe, dry glue, glue... Etc.. The dry glue without smoke and natural rubber, color to dry shallow, suitable for light and color products
