1. DEFINITIONS of SVR CV60, CV50
Technical Natural Rubber SVR CV is a rubber product line with stable viscosity. Two types of SVR CV rubber mainly include
SVR CV50
SVR CV60.
The rubber tree variety and the year of planting have a great impact on the quality of the product
In the developed rubber producing countries, in the production process, people are always equipped with main measuring and testing equipment, for example: 10 & 20 latex production is equipped with a plasticity meter, CV rubber is a machine. Viscosity measurement (you can still use a plasticity gauge to save money).
The control of the production process by measuring instruments for timely correction is very important to give the manufacturer the means to achieve his production goals by testing.
2. APPLICATIONS OF SVR CV RUBBER
Because CV (constant viscosity) rubber has the characteristic property of constant viscosity and flexibility, it is preferred by manufacturers. Flexibility is very convenient in the rolling process (such as low energy, synthesis, etc.) The combination of substances in a good mixture, high adhesion) will create a good and uniform product.
This type of rubber is used to make elastic bands, glue, tire sidewalls, table tennis rackets …
3. HIGHLIGHTS SVR CV60, CV50
Stable viscosity
The flexibility and adhesion have confirmed this rubber to thrive in the domestic market as well as the world.
