Reclaim Rubber for Compression-Molded Rubber Goods
Reclaim rubber for molded goods replaces virgin polymer at lower cost in compression-molded parts such as mats, railroad parts and stationary rubber parts. EPDM, SBR 1502, natural rubber and whole tire reclaim are all used this way, as a blend partner or as the only polymer in the compound.
- Grades
- EPDM, SBR 1502, NR, WTR
- SBR 1502 compression set

Typical molded products
- Rubber mats
- Railroad parts
- Stationary rubber parts
- Mechanical rubber goods that need wear and abrasion resistance
Choosing a reclaim grade for molding
- EPDM reclaim (853+ PSI, 55 ± 5 Shore A): molded EPDM compounds that rely on consistent tensile and scorch safety.
- SBR 1502 reclaim (950+ PSI, 50 ± 5 Shore A, compression set 25% max): mechanical rubber goods that need wear and abrasion resistance; a lower-cost alternative to virgin SBR 1502, including heavily loaded transit flooring.
- Natural reclaim rubber (430+ PSI, 60 ± 5 Shore A): NR compounds where reclaimed NR cuts virgin natural rubber cost.
- Whole tire reclaim (#704 1,067+ PSI, #504 640+ PSI, #522 570+ PSI): NR/SBR compounds that keep good aging properties and stable viscosity at lower cost.

Mixing and molding
- One or two pass cycles on a Banbury or open mill, without sticking.
- Blends with other elastomers, oils, carbon black, processing aids, accelerators and sulfur.
- Blend levels depend on the part; reclaim can replace part of the virgin polymer or serve as the polymer on its own.
Supply and lead time
Pickup from our warehouse in Columbus, OH, or door delivery of full or partial truckloads to the Northeast, Midwest, South, West Coast and Canada. Capacity is 500+ MT per month across all grades. A full truckload is 43,000 lb, lead time is 4–6 weeks (4 weeks for SBR 1502), and every lot is certified and ships with a COA and MSDS.
Have cured scrap of your own?
Molders: we can convert your cured scrap into masterbatch.
We run the same conversion for manufacturers through contract toll processing, and can return the masterbatch to your own mixing room.

Reclaim rubber for molded goods: common questions
What molded products use reclaim rubber?+
Mats, railroad parts, stationary rubber parts and other mechanical rubber goods.
Which reclaim grade is best for compression molding?+
Match the base polymer: EPDM reclaim for EPDM parts, SBR 1502 reclaim for SBR, natural reclaim for NR, and whole tire reclaim for NR/SBR compounds.
Does reclaim rubber hold its properties in a molded part?+
Whole tire reclaim keeps good aging properties and compound viscosity; SBR 1502 reclaim has a 25% maximum compression set. Test against your own part spec.
Is there a starting recipe?+
Yes. The SBR 1502 reclaim page lists a model compound at 100 phr recycled rubber (115.15 phr total).
How fast can I get a truckload?+
4 weeks for SBR 1502 and 4–6 weeks for the other grades; a full truckload is 43,000 lb.
24tons picks up manufacturers' rubber process scrap, converts it into reusable raw material through vetted contract toll processors and reclaimers, and returns it to the original manufacturer (closing the loop) or distributes it into other qualified applications.
