SVR 3l (TSR 3L)
DEFINITION
SVR 3L (equivalent to technical rubber TSR 3L) is a high quality natural rubber, in the form of crumb rubber (or block rubber), common in preliminarily processed rubber and produced by many factories in Cameroon.
In addition, the main source of raw materials for SVR 3L natural rubber production is latex.
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.
WHAT IS SVR 3l (TSR 3L) NATURAL RUBBER?
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…
Light color
High level of purity
High elasticity and elongation
Good aging resistance
SVR 3L QUALITY SPECIFICATIONS ACCORDING TO TCVN 3769:2016
In particular, SVR 3L is also known as block rubber is graded according to precise technical parameters such as dirt content, ash content, nitrogen content, volatile matter and properties of the rubber such as its Wallace Plasticity (PO) and its Plasticity Retention Index (PRI).
Dirt content (max% wt), retained on 45 micron sieve: 0,03
Ash content (max % wt): 0,50
Nitrogen content (max % wt): 0,60
Volatile matter (max % wt): 0,80
Initial plasticity ( Po ) (min): 35
Plasticity retention index (PRI) (min): 60
Lovibond Color I Index (max) Difference between samples (max):
PRODUCTION PROCESS OF NRCL RUBBER
SVR 3L 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 3L 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.
