Natural Rubber SVR CV60

Natural Rubber

Natural rubber is a durable, elastic material derived from the latex of rubber trees, primarily Hevea Brasiliensis. It is widely used in industries such as automotive, manufacturing, and consumer goods due to its high resilience, flexibility, and strength. Natural rubber plays a crucial role in producing tires, seals, hoses, and various industrial products.

Technical Specified Rubber

Technically Specified Rubber (TSR) is classified based on impurity levels, plasticity retention, and processing characteristics. Below are the specifications for common TSR grades, including TSR 5, TSR 10, TSR 20, TSR CV, SVR 3L, and TSR L.

Key Characteristics of TSR Grades

TSR 5 & TSR 10: High-purity rubber used in premium tire manufacturing and industrial applications.
TSR 20: The most commonly used grade in the tire industry due to its cost-effectiveness and balanced properties.
TSR CV: Designed for applications requiring consistent viscosity, such as precision rubber products.
SVR 3L: A high-quality Vietnamese rubber grade with low dirt content and high elasticity, widely used in high-performance rubber products and medical applications.
TSR L: A light-colored, high-purity rubber grade known for its low dirt content and excellent elasticity, often used in applications requiring superior quality and cleanliness, such as medical and food-grade products.
