Raw latex is divided into two main sources that is not only rubber fields owned by state-owned companies but also latex from smallholders and traders.
2. APPLICATIONS
In order to meet the products of L or 3L grade, it must satisfy important characteristics such as Po, color (Lovibond), dirt content, storage … in standard TCVN 3769: 2016.
With high PO parameter characteristics (PO> 35), SVR 3L natural rubber products are applied to products that require high elasticity as well as high abrasion resistance.
Common applications of SVR 3L natural rubber include car tires, belts, power cables, bicycle guts, washers, other rubber parts in cars, etc.
Another key point, SVR 3L is also used in products that need light color high quality straps, cables, shoe soles, medical products, electronics industry, high quality products in the medical industry…

5. PRODUCTION PROCESS OF APT RUBBER
SVR 3L is produced entirely from latex of garden plants according to Vietnamese standards (TCVN: 3769). Firstly, latex is preserved by ammonia or sodium sulfite. Then the rubber is then coagulated with formic acid, followed by shredding by passing through a rolling mill, washing system and hash. After the crumb rubber is dried, it will be compressed into blocks and packed in polyethylene bags. SVR 3L rubber is a light colored rubber with a low content of dirt and odorless.
Finally, our SVR 3L rubber processing production line is supplied and maintained periodically by Quang Trung Mechanical Co., Ltd., a reputable company in the mechanical industry, manufacturing production lines and water treatment systems. waste in Vietnam rubber industry.
