Raakakumilevyjä

Raakakumilevyjä, often translated as raw rubber sheets or unvulcanized rubber sheets, are a foundational material in the rubber industry. They are produced by processing natural rubber or synthetic rubber into flat, flexible sheets before any vulcanization process has occurred. This means the rubber remains in a soft, pliable state, retaining its inherent elasticity and tackiness. The manufacturing process typically involves milling and calendering, where raw rubber is passed through heated rollers to achieve a uniform thickness and smooth surface.

The primary purpose of raakakumilevyjä is their use as a precursor material for a wide range of rubber products. Their unvulcanized state allows them to be easily molded, shaped, and compounded with various additives such as fillers, accelerators, and antioxidants to achieve specific properties in the final product. Industries such as automotive, manufacturing, and construction utilize these sheets for applications like tire production, conveyor belts, seals, gaskets, and protective coverings. The tackiness of the raw rubber also makes them useful for bonding layers of rubber together during manufacturing processes. The quality of the raakakumilevyjä directly impacts the performance and durability of the finished rubber goods.
