Material Matters: Vulcanised Rubber Sole Construction
Vulcanised rubber was an obvious choice for shoe soles. It provided more grip than leather and wouldn’t weaken in the wet. The earliest use of rubber soled shoes goes all the way back to 1876, when a company in the UK began making plimsolls for croquet.

Rubber and its Types | Chemistry Learning
Difference between Vulcanized rubber and Natural rubber. The new or vulcanized rubber obtained has properties that are just opposite to that of natural rubber. These properties are. Vulcanized rubber has excellent elasticity. Low water absorption tendency; It is resistant to the action of organic solvents; It is resistant to attack of oxidizing agents. Vulcanized Rubber is an improved form of Natural rubber.

Natural rubber is often vulcanized - a process by which the rubber is heated and sulfur, peroxide or bisphenol are added to improve resistance and elasticity and to prevent it from perishing. Carbon black is often used as an additive to rubber to improve its strength, especially in vehicle tires, which account for about 70% (~9 million tons) of carbon black production.

Send InquiryWhat is vulcanised rubber?
Vulcanization or vulcanisation is a chemical process for converting natural rubber or related polymers into more durable materials via the addition of sulfur or other equivalent curatives or accelerators. These additives modify the polymer by forming cross-links (bridges) between individual polymer chains.
