Product overview

SIR 3L is the lightest-color Indonesian TSR grade in our catalogue, milled from field latex and fresh coagulum streams. Dirt content is at or below 0.03%, ash at or below 0.50%, and PRI is at or above 60. Mooney ML (1+4) at 100 °C centres at 50 for premium tread and specialty compounds that name light TSR on the purchase order.

SNI 1903 light-color limits

Dirt at or below 0.03%, ash at or below 0.50%, volatile matter at or below 0.80%, nitrogen at or below 0.60%, PRI at or above 60, Mooney ML (1+4) at 100 °C of 50 plus or minus 5. Laboratory testing is completed before bales clear for export stuffing.

Premium tread and specialty uses

Light-color passenger tread, premium sidewall compounds, and specialty goods where coagulum TSR at SIR 10 limits is not clean enough. SIR 3L is not a volume replacement for SIR 20; it is a scheduled premium grade.

Packing and lead time

35 kg bales on shrink-wrapped pallets, 19.6 MT per 20 ft container. Lead time three to four weeks FOB Jakarta or Belawan because latex streams are allocated to confirmed orders. Quarterly contracts secure mill slots.

Frequently asked questions

Ordering, samples, shipping, and payment, answered by our export desk.

What dirt limit defines SIR 3L light-color TSR on this product page?

Dirt at or below 0.03% (w/w) with ash at or below 0.50% and PRI at or above 60 on the export COA. These are the tightest limits in our TSR catalogue.

What lead time should buyers plan for SIR 3L light-color TSR export orders?

Field-latex and fresh coagulum streams are scheduled to export lots rather than pulled from open stock. Book ahead for premium tread campaigns that name SIR 3L on the raw-material specification.

What container MOQ applies to SIR 3L orders?

19.6 MT in one 20 ft FCL, 560 bales of 35 kg on shrink-wrapped pallets. Same bale format as SIR 10 and SIR 20 for straightforward warehouse handling.

When should I specify SIR 3L instead of SIR 10 premium TSR?

Specify SIR 3L when your compound needs field-latex light TSR with dirt at or below 0.03% and PRI at or above 60. SIR 10 suits coagulum premium tread when 0.10% dirt is acceptable.
