WHAT IS SVR 5 NATURAL RUBBER?
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.
SVR 5 has darker color than SVR 3L. The main source of raw materials for SVR 5 natural rubber production is latex. SVR 5 main features are
- High level of purity
- High elasticity and elongation
- Good aging resistance
- Bright color (although color is darker than SVR 3L but SVR 5 is still considered as brighter than other types of SVR rubber)
- Cheaper than SVR 3L
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> 30), it’s products are applied to products that require high elasticity as well as high abrasion resistance. Common applications of SVR 5 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…

QUALITY OF SVR 5 NATURAL RUBBER ACCORDING TO TCVN 3769:2016
Quality specifications according to TCVN3769:2016 standard is described as below:
- Dirt content (max% wt), retained on 45 micron sieve: 0,05
- Ash content (max % wt): 0,60
- Nitrogen content (max % wt): 0,60

There is another rank of SVR 5 called SVR 5S, which characterised P0 from 30 to 41.
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.
