natural rubber

usage and fabrication process

The natural rubber is an important agricultural product that is harvested from the bark of the rubber tree, which mainly grows in tropical regions. It is used in many products such as tires, gloves, rainwear, pipes, balloons and toys, as well as various industrial applications.

Natural rubber is produced by harvesting latex from the rubber tree. Latex is a white, milky liquid that flows when the tree’s bark is incised. It is then collected in specially designed containers called “cupules” and processed to remove water and impurities.

The purified latex is then transformed into natural rubber by cooking it in molds at high temperatures. This cooking process allows the rubber to harden and take the desired shape. Natural rubber is then ready to be used in a variety of products.

Natural rubber is a valuable product because it is durable, wear-resistant, and can be recycled. It is also biodegradable, which means it does not pollute the environment when discarded.

grades and quality

There are several classes and grades of natural rubber quality available in the international market. The most common classes and grades are as follows:

  1. RSS (Rubber Smoked Sheets) Grade: This class of rubber is considered the highest quality natural rubber available in the market. RSS rubber is obtained through the smoking method, which involves using smoke to coagulate the latex and produce high-quality rubber sheets. RSS quality grades are numbered from 1 to 5, with grade 1 being the highest in terms of purity and quality.

  2. SIR (Standard Indonesian Rubber) Grade: This class of rubber is produced in Indonesia and is generally considered of high quality. SIR quality grades are numbered from 10 to 60, with grade 10 being the highest in terms of purity and quality.

  3. SMR (Standard Malaysian Rubber) Grade: This class of rubber is produced in Malaysia and is also considered of high quality. SMR quality grades are numbered from 10 to 50, with grade 10 being the highest in terms of purity and quality.

  4. TSR (Technically Specified Rubber) Grade: This class of rubber is produced from different types of natural rubber and is often used in specific industrial applications. TSR quality grades are numbered from 10 to 50, with grade 10 being the highest in terms of purity and quality.

  5. Concentrated Latex Grade: This class of rubber is produced from concentrated latex and is often used for the manufacture of latex products such as surgical gloves. Concentrated latex quality grades are numbered from 60 to 70, with grade 60 being the highest in terms of purity and quality.

It is important to note that quality grades may vary depending on the standards and specifications of each country or region. Natural rubber quality grades can also vary depending on dry matter content, ash content, and other quality criteria.
