RSS 3 Tire Grade Smoked Sheet

Green Book RSS 3 sheets for tire tread and general rubber goods.

RSS 3 is the standard smoked-sheet grade for tire tread and general rubber goods in plants that still run sheet blends. Dirt content is at or below 0.20%, PRI at or above 50, and sheets are visually graded to Green Book RSS 3 before export stuffing. It pairs with TSR volume programmes when a tire maker keeps RSS in specific tread lines.

Tire tread applications

RSS 3 appears in tread compounds where historical recipes reference smoked sheet rather than TSR alone. Blending RSS 3 with SIR 20 is common in Asian tire plants. Confirm your compound design before switching sheet suppliers; we provide pre-shipment samples on request.

Quality parameters

Laboratory limits mirror SIR 20 on dirt at 0.16% but add Green Book visual classification. PRI at or above 50, ash at or below 1.00%, volatile matter at or below 0.80%. Sheet-grade on the specification sheet states RSS 3 (Green Book) explicitly.

Export from Sumatra

Sheets ship FOB Belawan or Palembang in wooden crates or palletised bundles. Lead time is two to three weeks on standard programmes. Certificate of origin, weight certificates, and Halal documentation travel with the lot.

RSS 3 FAQ

Tire-grade smoked sheet ordering and specs.

Which tire compounds typically call for RSS 3 smoked sheet from Indonesia?

Tread and general rubber goods lines where the raw-material specification still references Green Book RSS 3. Many plants blend RSS 3 with SIR 20 TSR rather than running sheet-only recipes.

Should I buy RSS 3 sheet or SIR 20 TSR for the same tire plant?

SIR 20 handles bulk volume at lower unit cost. RSS 3 suits tread campaigns that require Green Book sheet designation or specific processing behaviour in older mixers. We can supply both under one contract for split campaigns.

What minimum volume applies to RSS 3 smoked sheet containers?

19.6 MT net in one 20 ft FCL, 33.33 kg sheets in crates or palletised bundles. Lead time is two to three weeks FOB Belawan or Palembang on standard availability.

Which ports load RSS 3 sheet containers for export?

Belawan and Palembang are primary FOB points for Sumatra sheet mills. Jakarta is used when inland logistics favour Java consolidation. We quote FOB, CFR, or CIF to your destination.
