Soft vulcanized rubber
WebVulcanized rubber is elastic & less sticky not alike raw rubber, doesn’t harden or soften much with cold weather except at very high temperatures. In addition, it is highly resistant to abrasion. The cross linking improves its tensile strength. Vulcanized rubber is ten times stronger as well as more rigid than natural rubber. WebHard rubber is vulcanized rubber in which 30% to 50% of sulfur has been mixed before heating; soft rubber contains usually less than 5% of sulfur. After the sulfur and rubber (and usually an organic accelerator, e.g., an aniline compound, to shorten the time or lower the heat necessary for vulcanization) are mixed, the compound is usually placed in molds and …
