WHAT IS SVR 3L (TSR 3L) RUBBER ?

 

1. DEFINITION OF NATURAL RUBBER SVR 3L :

  • SVR 3L (equivalent to TSR 3L technical rubber) is a high-quality natural rubber, in the form of nuggets, popular in primary rubber and manufactured by many factories in Vietnam.
  • The source of raw materials for the production of natural rubber SVR 3L is latex.
  • Raw latex is divided into two main sources: orchards owned by state-owned companies and latex purchased from smallholders, big farmers and traders.

2. APPLICATIONS

  • In order to meet the product's level of L or 3L, it must satisfy important characteristics such as Po, color (Lovibond), dirt content, retention .... which are specified in 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, cables, bicycle tubes, washers, other rubber parts in cars, etc.
  • In addition, SVR 3L is also used in products that need bright colors, high quality belts, power cables, shoe soles, medical products, electronics industry, high quality products in the medical industry. economic…

3. HIGHLIGHTS OF SVR 3L . RUBBER

  • Light color
  • High elasticity, stretch
  • Good temperature aging resistance
  • High purity

4. TECHNICAL STANDARDS OF SVR 5 QUALITY RUBBER BY TCVN3769:2016

SVR 3L is a high quality block engineering rubber with strict requirements for dirt content, ash content, nitrogen content, volatile matter content, plasticizer (PO), plasticity retention index (PRI)…

  • Contaminant content retained on 45m sieve, % m/m, not more than: 0.03
  • Ash content, % m/m, not more than: 0.50
  • Nitrogen content, % m/m, not more than: 0.60
  • Volatile matter content, % m/m, not more than: 0.80
  • End ductility ( Po ), not less than: 35
  • Plasticity retention index (PRI), not less than: 60
  • Lovibond color index, single, no more than: 6
  • Viscosity Mooney ML (1' + 4' ) 1000C

5. SVR 3L RUBBER PRODUCTION PROCESS OF VINAHUGO COMPANY

  • SVR 3L is produced entirely from garden latex according to Vietnamese standards (TCVN: 3769). Latex is preserved with ammonia or sodium sulfite. The rubber is then coagulated with formic acid, followed by shredding by passing through a rolling mill, washing system and shredder. After the nuggets are dried, they will be compressed into blocks and packed in polyethylene bags. Standard SVR 3L rubber is light colored rubber with low dirt content and no odor.
  • Natural Rubber SVR 3L (TSR 3L) must be circulated in a sheltered, dry and cool warehouse, and protected from direct sunlight, rain, dirt, vermin and other insects, and impact strong during storage, transportation and unloading.
