Natural rubber

We are investcom, one of the leading exporters of natural rubber in vietnam with 10 years of experience. As one of 4 biggest natural rubber exporting countries in the world, we are confident that we would give you the highest satisfaction. Producting from advanced technology, input materials through strict inspection, processing standards and exact packing, natural rubber has become our pride in transactions. Here is information of svr 20 - one of our pride:
svrcv60 is one of the standard vietnamese rubber products. Latex rubber directly exploited from rubber plantation and carried to factory for processing. Latex rubber after being processed into crumb will be dried at more than 100oc (110+-5oc) and pressed into bale at high pressure then packed according to general standards of 33.33kgs or 35kgsbale
due to constant viscosity and flexibility, cv (constant viscosity) rubber is liked by manufacturers. The flexibility is convenient for lamination (low energy, good synthesis of substances in a mixture, high adhesion) to create a good and uniform product.this type of rubber is used to manufacture rubber bands, glue, lateral surface of tyres, racket surface
