SVR 3L is produced entirely from latex of garden plants according to Vietnamese standards (TCVN: 3769). Firstly, latex is preserved by ammonia or sodium sulphite. 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 coloured rubber with a low content of dirt and odourless.

Features of SVR 3L Natural Rubber

• Its appearance is light colour and odourless
• It offers high level of purity
• It has high elasticity and elongation
• Has good ageing resistance
• It offers excellent tensile strength, high elasticity, high tear resistance which makes it a preferred choice.

Natural Rubber have good resilience, abrasion and surface friction properties and excellent compression set. It has low hysteresis and rolling resistance with high fatigue resistance and remains flexible at low temperatures. It has poor resistance to oil, sunlight and ozone and limited thermal capability.

Natural rubber has superior tear strength and excellent resistance to heat buildup continues to make it a favored ingredient for high-performance tires for race cars, trucks, buses and aircraft. Other applications include tank lining, engine mounts, seals, vibration dampening and diaphragms.
