Common Questions about Mixtures of SVR 3L
What Are Mixtures of SVR 3L?
Mixtures of SVR 3L are blended natural rubber grades produced by combining SVR 3L with a controlled proportion of SBR 1502 (typically around 2.5%).
This formulation is designed to improve cost efficiency and processing stability, where premium appearance and maximum cleanliness are not mandatory.
Why is SBR 1502 added to Mixtures of SVR 3L?
SBR 1502 is added in a low, controlled ratio to:
- Improve processing stability
- Enhance batch-to-batch consistency
- Support cost optimization in high-volume production
The blend ratio is kept limited to preserve the core characteristics of SVR 3L.
Why are Mixtures of SVR 3L preferred in certain markets such as China?
Mixtures of SVR 3L are widely adopted in cost-driven manufacturing markets, including China, because:
- They offer a strong price–performance balance
- The formulation suits high-volume industrial production
- Zero import tax on natural rubber mixtures products
This makes blended grades commercially attractive for large-scale users.
Are blend ratios fixed?
The standard SBR 1502 content is ~2.5%.
Alternative ratios may be discussed depending on application, pricing targets, and compliance requirements.
Is EUDR-aligned supply available for Mixtures of SVR 3L?
Yes. EUDR-aligned supply may be available depending on the blend structure and sourcing model. Traceability documentation, ISO certifications, and origin documents are provided upon confirmation.

STABILIZE PRODUCTION WITH COST-OPTIMIZED MIXTURES OF SVR 3L
Rising raw-material costs and price volatility require practical material solutions. As a result, Mixtures of SVR 3L are formulated for manufacturers seeking stable processing performance and cost efficiency, where premium appearance and maximum cleanliness are not mandatory.
APT Rubber produces Mixtures of SVR 3L by blending SVR 3L with a controlled proportion of SBR 1502 (typically around 2.5%), creating a balanced formulation suitable for high-volume rubber manufacturing.
Compared with pure SVR 3L, these mixtures focus on processing stability and commercial viability, helping manufacturers manage BOM costs while maintaining acceptable functional properties in cost-sensitive applications.
Why Manufacturers Choose Mixtures of SVR 3L from APT Rubber
- Cost-Optimized Formulation
Designed to reduce raw-material cost compared with pure SVR 3L, supporting competitive pricing strategies. - Stable Processing Performance

Our Quality Control Process
From rubber reception to final bale packing, we monitor 6 critical control points to ensure stable processing performance, controlled impurity levels, and consistent formulation for Mixtures of SVR 3L. Production is conducted in alignment with TCVN 3769:2016 for the natural rubber component. This grade is manufactured in our owned Vietnam natural rubber manufacturing facilities under ISO-aligned quality systems.
- Latex Reception: Incoming field latex is screened to verify raw material quality and remove visible contaminants prior to processing.
- Coagulation & Pre-Processing: Coagulation and material handling are carefully controlled to minimize contamination and preserve the natural properties of the rubber.
- Mechanical Processing: Crumbling and repeated washing reduce dirt and non-rubber constituents in line with impurity limits defined under TCVN 3769:2016 for SVR 3L.
- Controlled Mixing of SBR 1502: A measured proportion of SBR 1502 (typically around 2.5%) is introduced under controlled conditions to achieve uniform dispersion and batch-to-batch consistency. Mixing parameters are monitored to ensure formulation stability and predictable processing performance.
- Drying: Drying temperature and duration are controlled 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. Blend conformity is verified before release.
