WHAT IS SVR 3L (TSR 3L) NATURAL RUBBER?
DEFINITION
SVR 3L (equivalent to technical rubber TSR 3L) is a high quality natural rubber with light color, in the form of crumb rubber (or block rubber).
SVR 3L is common in preliminarily processed rubber and produced by many factories in Vietnam.
The main source of raw materials for SVR 3L natural rubber production is field latex. In Vietnam, raw field latex is divided into two main sources: rubber fields owned by state-owned companies and raw materials from smallholders and traders.
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.
Key features of SVR 3L natural rubber include:
- Light color
- High level of purity
- High elasticity and elongation
- Good aging 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…

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 Index (max) Difference between samples (max): 6
PRODUCTION PROCESS OF APT RUBBER
SVR 3L is produced entirely from latex of garden plants according to Vietnamese standards (TCVN: 3769:2016).
First, 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.
