SVR Rubber Manufacturer in Vietnam APT Rubber Product Range
APT Rubber is a Vietnamese natural rubber manufacturer established in 1998, supplying SVR rubber grades to international markets including the US, China, Korea, the EU, India, and Japan. This page provides an overview of SVR rubber grades produced in Vietnam and explains how to choose the right grade for industrial applications.
HOW TO CHOOSE THE RIGHT SVR GRADE FOR YOUR APPLICATION
Appearance-Critical Applications
Light color & Low Dirt and cleanliness matter
- Best suited for light-colored, low dirt products
- Recommended SVR Rubber grades: SVR 3L, SVR 5, Mixtures of SVR 3L
- Typical use cases: Footwear, consumer goods, elastic bands
Mooney-Controlled for Processing Stability
Consistent Mooney viscosity (ML) for predictable and repeatable processing
- Best suited for: High-volume and automated rubber manufacturing where viscosity control is more critical than light-color appearance
- Recommended SVR Rubber grades: SVR CV60, SVR CV50, SVR CV40, SVR CV70
- Typical use cases: CMB, automotive rubber parts, extrusion, calendering, precision molding
Mooney viscosity at 50 ± 5, offering easier flow for extrusion and molding applications.
Mooney viscosity at 40 ± 5, commonly used for thin-wall or complex molded rubber parts.
Cost-Driven Production
Performance & Budget
- Cost-sensitive rubber manufacturing where light appearance requirements are secondary. Choose these grades when cost efficiency matters more than color or cleanliness.
- Recommended SVR Rubber grades: SVR 10, SVR 20, Mixtures of SVR 10
- Typical use cases: Tires, mats, hoses, general industrial rubber goods
Commonly selected for high-volume rubber goods where appearance is not critical.
Designed to reduce material cost while maintaining acceptable processing performance.
Market-Specific & Custom Blends
Tailored formulations for cost optimization and processing stability
- Best suited for markets requiring cost-optimized rubber formulations with stable and predictable processing behavior
- Recommended SVR Rubber grades: Mixtures of SVR 10, Mixtures of SVR 3L
- Key Benefits: Cost optimization, processing stability and Market-specific formulation flexibility. These blends are commonly used in tariff-sensitive markets where formulation flexibility is required.
Designed for high-volume production where cost efficiency and stable processing are prioritized.
Selected when better cleanliness or light-color appearance is required.

FAQs
ASK US
ANYTHING
Is APT Rubber a manufacturer or a trading company?
APT Rubber is a natural rubber manufacturer, not a trading company. Founded since 1998, we operate our own processing facilities in Vietnam and manage sourcing, production, quality control, and export documentation in-house.
Which SVR rubber grades does APT Rubber supply?
APT Rubber supplies a range of SVR grades, including SVR CV60, SVR CV50, SVR 3L, and other SVR grades subject to seasonality and volume requirements. Each grade is produced in accordance with applicable Vietnamese standards and tested per shipment.
Is EUDR-ready SVR rubber available?
Yes. Traceability information is available for SVR rubber supplied by APT Rubber to support EUDR due diligence (DDS) requirements.
Relevant documentation, including Due Diligence Statements (DDS) and supporting traceability records, can be provided upon request, subject to buyer scope and agreed commercial terms.
Which quality and product standards does APT Rubber follow?
APT Rubber operates under a quality management system aligned with ISO 9001:2015 and an environmental management system aligned with ISO 14001:2015, supporting consistent production control, traceability, and environmental management.
SVR rubber supplied by APT Rubber is tested in accordance with TCVN 3769:2016, the Vietnamese national standard governing SVR rubber grades, including cleanliness, viscosity, and technical specifications. Quality results are documented for each shipment.
How do I choose the right SVR grade for my application?
Select the SVR grade based on your primary production priority.
If appearance and cleanliness matter, choose appearance-critical grades such as SVR 3L or SVR 5.
If processing stability is critical, Mooney-controlled CV grades are preferred.
For cost-sensitive production, industrial grades such as SVR 10 or SVR 20 are commonly used.
Market-specific blends are applied where formulation flexibility or cost optimisation is required.
What is the difference between CV grades and non-CV SVR grades?
CV grades are produced with controlled Mooney viscosity, offering more stable and repeatable processing.
They are selected when viscosity consistency is more important than color or appearance.
Non-CV grades are typically chosen based on appearance, dirt content, or cost considerations rather than viscosity control.
Are SVR mixtures lower quality than standard SVR grades?
No. SVR mixtures are formulation-driven products, not lower-quality materials.
They are designed to achieve specific cost, processing, or market requirements, often by blending natural rubber with controlled amounts of synthetic rubber such as SBR 1502.
Mixtures are widely used in high-volume and tariff-sensitive markets.
WE OWN TECHNOLOGY
Unlike other manufacturer, we design, build, and operate our own rubber processing systems, ensuring direct control over production stability, quality, and contamination risk.
QUALITY CONSISTENCY
Consistent quality is maintained through controlled sourcing, in-house processing, and batch-level monitoring across every stage of SVR rubber production.
FACTORY CAPACITY
Our combined processing capacity exceeds 40,000 metric tons annually, supporting stable, long-term SVR rubber supply for global buyers.
COMMITMENT on SUSTAINABILITY
Operations align with EUDR requirements and ISO 14001:2015 environmental management standards, supporting traceable and responsible natural rubber supply.
