Natural caucho es hecho de látex, y una parte de el no caucho componente contenido en el látex permanece en el sólido caucho natural contiene 92%-95% de caucho hidrocarburos, mien no caucho hidrocarburos cuenta para 5%-8%. Debido a diferentes fabrica métodos, diferentes producción áreas y incluso diferentes caucho estaciones, la proporción de estos ingredientes puede variar, variar, pero ellos están básicamente dentro del rango.

Protein can promote the vulcanization of rubber and delay aging. On the other hand, the protein has strong water absorption, which can cause the rubber to absorb moisture and mold, and the insulation is degraded, and the protein has the disadvantage of increasing heat build-up.

Acetone extracts are high-grade fatty acids and sterols, some of which act as natural antioxidants and accelerators, and others which help the powdered compounding agent disperse during the mixing process and soften the raw rubber.

The moisture in the dry glue does not exceed 1%, and it can be volatilized during processing. However, when the moisture content is too much, it will not only cause mildew during the storage of the raw rubber, but also affect the processing of the rubber, such as the compounding agent during mixing. Group; bubbles are easily generated during calendering and extrusion, and bubbles or sponges are formed during the vulcanization process.
