Natrual Rubber is a key export products for Vietnam. With it mother nature blessing, Vietnam owned hundreds of thousands hectare of rubber plantation.
Our manufacturer has all typical natural rubber product ranges from SVR CV60, SVR 3L, SVR 5, SVR 10, SVR 20.
Our products have been exported worldwide from S. America, Midle East to European and South Asia countries.
NATURAL RUBBER SVR CV 60
SVR CV 60 is a constant viscosity grade. It is produced by adding hydroxylamine neutral sulfate (HNS) and peptizer to the field latex before coagulation with acid. The coagulum is allowed to mature for some hours, reduced to crumbs by passing through a crusher, crepers, a shredder, dried and pressed into bales. The hydroxide amine inhibits the storage hardening reaction in natural rubber, which leads to an increase in its Mooney viscosity. Mooney vicosity (MV) range is 60 ± 5.
