WHAT IS SVR 5 NATURAL RUBBER?
1. DEFINITION
SVR 5 (equivalent to technical rubber TSR 5) is a high quality natural rubber, in the form of crumb rubber, common in preliminarily processed rubber and produced by many factories in Vietnam.
In addition, it has darker color than SVR 3L. The main source of raw materials for SVR 5 natural rubber production is latex. Not only raw latex is divided into two rubber fields owned by state-owned companies but also latex from smallholders and traders.
2. APPLICATIONS
In order to meet the products of SVR 5 grade, it must satisfy important characteristics such as Po, color (Lovibond), dirt content, storage … in standard TCVN 3769: 2016.
As a result from high PO parameter characteristics (PO> 35), it’s products are applied to products that require high elasticity as well as high abrasion resistance. Common applications of SVR 5S natural rubber include car tires, belts, power cables, bicycle guts, washers, other rubber parts in cars, etc, for instance.
It 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
Latex of garden plants according to Vietnamese standards (TCVN: 3769) is what SVR5 is produced entirely from. Firstly, it is preserved by ammonia or sodium sulfite. Secondly, the rubber is then coagulated with formic acid, followed by shredding by passing through a rolling mill, washing system and hash. Finally, after the crumb rubber is dried, it will be compressed into blocks and packed in polyethylene bags. At this point, It has a light colored rubber with a low content of dirt and odorless.
In fact, our SVR 5 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.
