SVR CV60 (or TSR CV60) natural rubber is a product line of natural rubber with stable mooney viscosity from 55 to 65.
Stabilize Your Production with Premium SVR CV60
Don’t let viscosity fluctuations slow down your mixing line. APT Rubber produces SVR CV60 (Constant Viscosity) specifically for manufacturers who require precision.
Unlike standard grades, our CV60 undergoes a rigorous viscosity-stabilization process using industry-standard agents to inhibit storage hardening. Our formulae guarantees a Mooney Viscosity of 60 (+/- 5) upon arrival at your factory.
Why Leading Manufacturers Choose APT Rubber:
- Guaranteed Stability: We guarantee minimum 6 months of Mooney viscosity stability. We understand shelf-life is your main concern, and unlike others, we commit to this claim.
- Energy Saving: Our soft, stable rubber requires minimal mastication, significantly reducing your electricity costs and mixing time.
- EUDR Ready: We provide full traceability data (geolocation) for every container, ensuring your products are safe for the European market.
- 25+ Years of Expertise: Established in 1998, we have over two decades of experience in processing natural rubber.
- Global Trust: Our SVR CV60 is currently trusted by buyers in USA, India, Korea, Germany and Malaysia.
- Direct Sourcing: Buy directly from our Vietnam factory to eliminate middleman margins.

Our Quality Control Process
From the rubber farm to the final bale, we monitor 5 critical control points to ensure our “6-Month Stability” guarantee.
Latex Reception: Screening for DRC and Ammonia content.
Viscosity Stabilization: Precise dosing of stabilizers agent.
Mechanical Processing: Crumbing and washing to remove dirt (0.02% limit).
Drying: Controlled temperature to maintain plasticity (PRI > 60).
Lab Testing: Every pallet is tested for Mooney Viscosity before packing.
Our natural rubber processing production line is supplied and maintained periodically by Quang Trung Mechanical Co., Ltd., a reputable company in the mechanical industry, manufacturing production lines, laboratory equipments and waste water treatment systems in Vietnam rubber industry.
APPLICATIONS
SVR CV60 is engineered for industries where process consistency is non-negotiable. Thanks to its stable Mooney Viscosity (60±5) and excellent tack properties, it eliminates the need for extensive premastication. This makes it the preferred raw material for high-precision manufacturing, from heavy-duty industrial belts to sensitive adhesive tapes
- Pressure-sensitive adhesives (PSA)
- Industrial glues (High Tack)
- Packaging & wrapping materials
- Tire treads & sidewalls
- Vibration-dampening pads
- Inner tubes & Engine mounts
- Conveyor belt covers
- Gaskets & Heavy-duty seals
- Industrial Hoses
- Table tennis rackets
- High-grade rubber bands
- Sports equipment
