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 Cameroon.
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.
APPLICATION
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 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…
TECHNICAL FEATURES
Light color
High level of purity
High elasticity and elongation
Good aging resistance
PRODUCTION PROCESS OF NRCL RUBBER
SVR 5 is produced entirely from latex of garden plants according to Cameroonian 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 5 rubber processing production line is supplied and maintained periodically by a reputable company in the mechanical industry, manufacturing production lines and water treatment systems. waste in Cameroon rubber industry.
