SVR 3L is a technically specified natural rubber grade supplied in block form. This page outlines the grade’s quality basis, test results for one sample, packing options and applications reported by Ngoc Chau. Buyers evaluating an SVR 3L supplier in Vietnam can also review the order details to confirm before requesting a quotation.
SVR 3L Grade and Quality Basis
SVR 3L, or Standard Vietnamese Rubber 3L, is a grade of technically specified natural rubber produced in Vietnam. Unlike Ribbed Smoked Sheet (RSS), which is assessed primarily by visual inspection, SVR grades are evaluated against technical requirements.
TCVN 3769:2016 is the Vietnamese national standard for SVR. The applicable specification and acceptance limits should be agreed between buyer and supplier for each order. Buyers referring to TSR 3L should confirm the required standard and technical limits in the purchase order rather than relying on the grade name alone.
SVR 3L Test Results
The table below summarizes results for the SVR 3L sample tested on 4 February 2026. These are sample results for reference; they are not guaranteed values for every shipment.
| Parameter | Test result | What it indicates |
|---|---|---|
| Dirt retained on 45 μm aperture | 0.007% m/m | Dirt retained during the test |
| Ash | 0.21% m/m | Inorganic residue measured in the sample |
| Volatile matter | 0.19% m/m | Volatile matter measured in the sample |
| Nitrogen | 0.45% m/m | Nitrogen content measured in the sample |
| Initial Wallace Plasticity (Po) | 43.3 | Initial plasticity under the test conditions |
| Plasticity Retention Index (PRI) | 91 | Plasticity retention under the test method |
| Lovibond colour | 4.5 | Colour index recorded for the sample |
| Mooney viscosity, ML (1′+4′) at 100°C | 67.8 | Mooney viscosity under the test conditions |
The report identifies the test basis as TCVN 3769:2016, based on ISO 2000:2014. Buyers should confirm the applicable batch COA, specification and acceptance requirements for each order.
SVR 3L Packing Options
The listed SVR 3L packing options include 33.33 kg and 35 kg bales, supplied loose or palletized. The following are reference loading quantities; final bale counts and shipment weights depend on the packing plan and container.
| Bale weight | Loose bales in 20′ DC | Palletized loading in 20′ DC |
|---|---|---|
| 33.33 kg | Approx. 600–630 bales; 20–21 MT | 36 bales/pallet × 16 pallets = 576 bales; approx. 19.2 MT |
| 35 kg | Approx. 600–630 bales; 21–22.05 MT | 36 bales/pallet × 16 pallets = 576 bales; approx. 20.16 MT |
Confirm the bale weight, loose or palletized preference, final container loading, wrapping material and any special packing requirements for the order.
Typical Applications
Based on applications reported by Ngoc Chau, SVR 3L has been used in or considered for natural rubber compounds for:
- Rubber bands
- Shoes and footwear components
- Shoe adhesives
- BOPP tape and related adhesive applications
- Selected molded rubber parts and other industrial rubber products
- Selected non-invasive medical equipment or accessories, subject to buyer requirements
Buyer enquiries and applications may also include rubber seals and gaskets, hoses, bellows, cushions, stoppers and liners. These examples do not establish suitability for every formulation or finished product. Grade selection depends on the buyer’s compound design, processing conditions and product requirements. Buyers should confirm suitability with their technical or compounding team.

FAQ
What is SVR 3L natural rubber?
SVR 3L is a technically specified natural rubber grade in block form under Vietnam’s Standard Vietnamese Rubber classification.
What is the difference between SVR 3L and RSS 1?
SVR 3L is evaluated against technical requirements for SVR grades. RSS 1 is ribbed smoked sheet rubber assessed primarily by visual inspection. Buyers should select the grade according to their compound, process and product requirements.
Are these SVR 3L test results guaranteed for every shipment?
No. The values shown are results for one tested sample. Confirm the applicable shipment specification and batch COA for each order.
What bale weights are available?
The listed options are 33.33 kg and 35 kg per bale. Availability should be confirmed for the order.
Can SVR 3L be shipped on pallets?
Palletized packing is listed as an option. The reference configuration is 36 bales per pallet and 16 pallets per 20′ DC, subject to final loading confirmation.
What information should I include in a quotation request?
Please include quantity, destination port, preferred bale weight and packing type, required technical specification, and document or inspection requirements.
