Common Questions about SVR 3L
Is your rubber EUDR Compliant?
Yes. APT Rubber supports EUDR-aligned supply for SVR 3L upon request. Traceability documentation and due-diligence information can be provided for EU-bound shipments in line with applicable requirements.
What is the closest replacement for SVR 3L, and why?
The most suitable alternative to SVR 3L depends on which performance or commercial factor is prioritized:
- SVR 3L is preferred when appearance quality and material cleanliness are critical to the finished product.
- SVR 5 is commonly selected for cost-sensitive applications where a darker appearance and higher impurity tolerance are acceptable.
- SVR CV60 may be considered when processing stability and consistency are prioritized over visual appearance, due to its controlled Mooney viscosity.
- Mixtures of SVR 3L are used in certain markets, such as China, as a cost-optimized alternative for applications with similar technical requirements.
Final material selection should always be confirmed through formulation and processing trials.
What is the difference between SVR 3L and SVR CV grades?
SVR 3L is specified based on cleanliness and impurity limits, while SVR CV grades are produced with controlled Mooney viscosity. SVR 3L does not have viscosity control.
What determines the color of SVR 3L?
The color of SVR 3L is primarily influenced by raw material quality (field latex cleanliness) and processing control, particularly the removal of dirt, bark particles, and non-rubber constituents during production.
SVR 3L is produced to stricter impurity limits than general-purpose SVR grades, which results in better visual cleanliness and a more uniform appearance, as reflected in its Lovibond color index requirement under TCVN 3769:2016.
Will the color of SVR 3L change over time?
Yes. Like all natural rubber, SVR 3L will gradually darken over time due to natural oxidative aging.
Color change may occur during storage as a result of:
- Exposure to oxygen
- Heat and sunlight
- Extended storage duration
This darkening is a natural characteristic of natural rubber and does not necessarily indicate deterioration of key physical properties if storage conditions are properly maintained.
Why is SVR 3L selected for appearance-sensitive products?
Due to its light color, lower dirt content and controlled impurity levels, SVR 3L is commonly used where visual uniformity and surface quality are important.
How should SVR 3L be stored to help maintain a lighter appearance?
To help preserve the visual cleanliness and slow color darkening, SVR 3L should be stored:
- In a cool, dry, and well-ventilated area
- Away from direct sunlight and heat sources
- Protected from moisture, rain, and water contact
- Away from strong oxidizing agents and chemicals
These storage practices align with standard natural rubber handling guidelines and help minimize premature aging and discoloration.

Our Quality Control Process
From the rubber farm to the final bale, we monitor 5 critical control points to ensure consistent cleanliness, controlled impurity levels, and compliance with TCVN 3769:2016 for SVR 3L.
This grade is manufactured in our owned Vietnam natural rubber manufacturing facilities under ISO-aligned quality systems.
- Latex Reception: Screening of incoming field latex to verify raw material quality and remove visible contaminants prior to processing.
- Coagulation & Pre-Processing: Controlled coagulation and handling to minimize contamination and preserve the natural properties of the rubber.
- Mechanical Processing: Crumbing and repeated washing to reduce dirt and non-rubber constituents in line with SVR 3L impurity limits defined under TCVN 3769:2016.
- Drying: Controlled drying temperature and duration to maintain stable plasticity and prevent premature thermal or oxidative degradation.
- Laboratory Testing: Each production lot is tested for key quality parameters including dirt content, ash content, nitrogen content, volatile matter, and plasticity (P₀ and PRI) prior to packing.
