* Description SVR 10
SVR 10 is made from field coagulum materials. The materials are precleaned by passing them through creper – hammermills and then stored some weeks for maturation before production. Mature materials are blended and soaked in the water to be clean, size reduction to crumbs, drying and baling. SVR 10 has good technological properties similar to SVR 20, but lower dirt content

* Description SVR 5
SVR 5 is a quality natural rubber. It is produced wholly from field latex. Field latex is preserved with ammonia or sodium sulfite. This is type of rubber which production process is the same SVR 3L grade. The field latex is coagulated with formic acid, and then make crumbs by passing through a crusher, some crepers and a shredder. After the dried crumbs are cooled and then compressed into blocks.

-Bicycle tubes
-Rubber threads
-Gas masks

* Description
SVR 10CV is produced from cuplumps. it has constant viscosity by added with only hydroxylamine neutral sulfate (HNS). It is produced through the two dryprebreakers equipment and cool processing line. This is a grade of rubber with constant viscosity. The hydroxylamine substance inhibits the storage hardening reaction in natural rubber, which leads to an increase in its Mooney viscosity.
* End Use
-Anti-vibration mounting products
-Metal bonding
-Low density sponge
-Rubber–metal bonded components
-Industrial rolls
-Special mechanical goods.
* Features
• Constant viscosity rubber
• Softer than technically standard other grades
• Homogenous viscosity

* Description
SVR CV50 is a constant viscosity grade. It is made by adding hydroxylamine neutral sulfate (HNS) and peptizer before coagulation with acid. The coagulum is allowed to mature some hours, reduced to crumbs by passing through a crusher, crepers, a shredder, dried and pressed into bales. The hydroxylamine inhibits the storage hardening reaction in natural rubber, which leads to an increase in its Mooney viscosity. Mooney vicosity (MV) is 50 ± 5.

-Vibration mountings for engines and machinery
-Railway buffers -bridge bearings

* Description
SVR CV 60 is a constant viscosity grade. It is made by only adding hydroxylamine neutral sulfate (HNS) to ammonia preserved field latex after reception at factory. HNS is only added before coagulation with acid. The SVR CV60 rubber is processed through some stages such as crushing, creping, crumbing, drying and baling. The hydroxylamine inhibits the storage hardening reaction in natural rubber, which leads to an increase in its Mooney viscosity. Mooney viscosity (MV) is 60 ± 5.
