伸工貿易 List of Products and Services

Natural rubber is broadly classified into three categories. 1. Latex This is an emulsion obtained by collecting the sap of rubber trees and adding ammonia (to prevent coagulation) to achieve a rubber concentration of about 60%. 2. RSS (Ribbed Smoked Sheet) Acid is added to the latex to coagulate it, which is then shaped into sheets. After that, it undergoes smoking (curing and drying) treatment, and the sheets are stacked and pressed into a rectangular bale. The standard weight of one bale is 111.11 kg. 3. TSR (Technically Specified Rubber) This is a higher-grade material obtained by coagulating latex with acid, as well as intermediate materials that have naturally coagulated in collection cups. These are crushed, granulated, washed with water, and then dried with hot air, followed by pressing into block-shaped bales. Technical grading is performed based on sample evaluation of each bale. The standard size of one bale is 33.33 kg or 35 kg.
