Common Questions about SVR CV60
Is your rubber EUDR Compliant?
Yes. APT Rubber is fully committed to EUDR (EU Deforestation Regulation) standards. We provide full traceability documentation for all shipments to Europe, ensuring your supply chain remains compliant and risk-free for our EUDR compliant SVR CV60.
What is the difference between SVR CV60 and SVR 3L?
SVR CV60 is a Constant Viscosity rubber, meaning it maintains its softness and workability without needing pre-mastication. SVR 3L is graded for its light color. CV60 is superior for precision industrial adhesives and automotive parts where consistency is critical.
Does your SVR CV60 require premastication?
No. Because it is a Constant Viscosity (CV) grade, it saves your production line time and energy costs by eliminating the breakdown phase. It is ready for immediate compounding.
Do you provide a Certificate of Analysis (COA)?
Yes, every shipment of our SVR CV60 is accompanied by a comprehensive Certificate of Analysis (COA). Our rubber is tested to meet or exceed Vietnamese Standard TCVN 3769:2016.
Why is SVR CV60 preferred for automotive parts and adhesive applications?
SVR CV60 is engineered for high-precision industries where material uniformity is critical. Its specific benefits include:
Automotive: Its superior resilience and consistent Mooney viscosity make it the top choice for vibration-damping parts, engine mounts, and windshield wiper blades.
Adhesives: The rubber provides high “green strength” (inherent strength before curing) and constant adhesiveness, ensuring a reliable bond in industrial tapes and chemical formulations.
Reduced Rejects: Uniform texture and minimal shrinkage during milling lead to significantly lower reject rates in extruded and molded rubber goods.
How do you ensure long-term quality and storage stability?
Natural rubber can “stiffen” during storage, but SVR CV60 is treated to prevent this by:
Viscosity Stabilization: We add a stabilization agent during the latex stage to ensure the rubber maintains its Mooney viscosity even after long-term storage or transoceanic shipping.
Storage Best Practices: To maintain these properties, we recommend storing the rubber in a cool, dry, and ventilated warehouse, away from direct sunlight and high humidity.
Quality Verification: Every batch is tested in labs certified.
Packaging & Shipping DAta
APT Rubber offers flexible packing solutions for our natural rubber products to meet diverse international shipping requirements. We provide standard 33.33kg and 35kg bales, wrapped in either Thin PE (dispersible) or Thick PE (strippable) film based on your processing needs.
Customers can choose between Loose Bale packing for maximum tonnage or Pallets for easier unloading. Our standard 20ft container load capacity ranges from 19.2 Metric Tons (MT) to 20.16 Metric Tons (MT).

| Bale Wrapping (PE) | Thin PE (Dispersible) or Thick PE (Strippable) |
| Packing Methods | Loose Bales (Floor Loaded) or Pallets |
| Container Capacity (20ft) | Pallet: 19.20 MT – 20.16 MT / Loose Bales: 21 MT |
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, Japan, Germany and Malaysia.
- Direct Sourcing: Buy directly from our Vietnam factory to eliminate middleman margins.
