1. DEFINITIONS NATURAL RUBBER SVR 3L
SVR 3L (equivalent to TSR 3L technical rubber) is a high-quality, granulated natural rubber that is 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. APPLICATION
In order to meet the product standard L or 3L, it must satisfy important characteristics such as Po, color (Lovibond), content of dirt, 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, power cables, bicycle guts, 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…

5. SVR 3L RUBBER PRODUCTION PROCESS OF NAM ĐẠT COMPANY
SVR 3L is produced entirely from latex from orchards 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 covered warehouse, dry and cool, and protected from direct sunlight, rain, dirt, insects and other insects, and impact strong during storage, transportation and loading and unloading.
