These are virgin polymers that came off the producer’s line just outside a grade’s spec: near-prime lots, transition material made during a grade change, and off-grade lots with color specks or minor contamination. They go from the OEM to you, never through a compounder’s warehouse. Manufacturers use them as a lower-cost polymer, blended with prime in parts made to a wide spec. Tell us the polymer, the form and what you make, and we match lots from current stock.
Specs & packing
- EPDM
- Amorphous and semi-crystalline, low to high viscosity; oil-extended lots too

- Butyl (IIR), chlorobutyl and bromobutyl
- Lots
- Near-prime, transition (grade changeover) and off-grade
- Form
- Pellets, bales, blocks
- Packing
- Bags on pallets, big bags or boxes
- Supply

OEM Off-spec Polymers: common questions
What is the difference between near-prime, transition and off-grade?+
Near-prime is just outside the grade’s spec. Transition material is made while the line changes from one grade to another, so its properties span both. Off-grade failed an inspection, usually for color specks or contamination.
Who makes it?+
A major polymer producer. We do not publish the producer’s name or grade codes; lot details come with your offer.
How do I see what is available?+
Ask for a quote with the polymer, form, application and quantity. We reply with the lots that fit.
Have aged or off-spec polymer to sell?
We also buy aged, expired and off-spec polymer bales from compounders and manufacturers, and recycle them.
