WHAT IS SVR 10 NATURAL RUBBER?

DEFINITION

SVR 10 (or TSR 10) is a type of natural rubber produced from secondary latex, so the nature of rubber is hard. But when using this rubber mixed with RSS, CV50 and Latex will produce very good products, especially meeting the basic requirements of tire technology.

The raw material for processing this rubber is secondary latex (latex, cup, latex) they are mixed together in a suitable proportion to create quality products.

The different nature from the raw materials used to process this type of natural rubber requires a more rigorous quality control than classes derived from latex (SVR L, CV). The production of rubber crumb from rubber latex takes a lot of steps: preliminary washing of materials, chopping, shredding (reducing size), drying …

APPLICATIONS

Advantages of using SVR 10 includes:

Cost-Effective: Made from field coagulum → lower price than SVR 3L.
Good Strength: Adequate mechanical properties for many rubber goods.
Applications: Truck & bus tires, conveyor belts, molded goods, footwear, adhesives.

SVR 10 (TSR 10) has the nature of hardness. Therefore, in tire technology, rubber is mixed with low-level RSS and CV50 to produce high quality products.

In addition, it is combined with grades from latex to create a GP (general purpose) product that meets the basic requirements of tire technology.

Other applications include: tire repair industry, anti-shock cushioning products, railway rubber, inner tubes, conveyor belts, footwear…

PRODUCTION PROCESS OF SVR 10 at APT RUBBER

Step 1: Raw Material Collection

SVR 10 is produced mainly from field coagulum (cup lumps, tree lace, smallholder scraps).
Collected material is sorted to remove contaminants (stones, wood, metal).

Step 2: Washing

Cup lumps and scraps are thoroughly washed in large drums or water channels.
This step reduces dirt, bark, and other non-rubber impurities.

Step 3: Mastication & Size Reduction

Washed rubber is fed through crepers and shredders to break down the lumps.
Creates uniform sheets or crumbs for easier drying.

Step 4: Drying

Crumbed rubber is dried in hot-air dryers or tunnel ovens at controlled temperatures.
Moisture is reduced to ≤ 0.8% to meet TCVN/ISO standards.

Step 5: Grading & Quality Control

Each batch is tested for:
- Dirt content: ≤ 0.08% (higher than SVR 3L but still acceptable for many uses).
- Ash, nitrogen, and volatile matter.
- Mooney viscosity and PRI (Plasticity Retention Index).

Step 6: Baling & Packaging

Dried rubber is pressed into 33.33 kg or 35 kg bales.
Wrapped in polyethylene film and stacked on 1.2 MT pallets (wooden or steel).
Each bale is marked with grade, batch, and production date for traceability.

Step 7: Storage & Shipment

Stored in dry, ventilated warehouses.
Shipped globally under FOB, CIF, or DAP terms, with COA (Certificate of Analysis) provided.
