Vulkaniseerida

Vulkaniseerida is the Estonian term for vulcanization, a chemical process that transforms rubber and other elastomers into more durable materials. Discovered by Charles Goodyear in 1839, vulcanization involves heating natural or synthetic rubber with sulfur or other curatives. This process creates cross-links between polymer chains, significantly improving the rubber's strength, elasticity, and resistance to heat, cold, and abrasion.

Before vulcanization, rubber was sticky in heat and brittle in cold, limiting its practical applications. The introduction of sulfur, often with accelerators and activators, allows for controlled cross-linking at much lower temperatures and shorter times than previously possible. This makes the resulting rubber more stable and less prone to degradation.

The vulcanization process is fundamental to the production of a vast array of rubber products, including tires, hoses, belts, footwear, and seals. The specific properties of the final rubber product can be fine-tuned by adjusting the type and amount of curatives used, as well as the temperature and duration of the vulcanization process. Modern vulcanization techniques can also employ other agents like peroxides or metallic oxides for specific applications requiring enhanced resistance to oil, chemicals, or extreme temperatures. The term "vulkaniseerida" refers to the action of performing this essential industrial treatment on rubber.
