Avient Materials: 7 Questions Procurement Asks (But Won't Say Out Loud)

Avient Materials: What You Actually Need to Know Before the PO

Over the past 6 years of tracking every invoice for a mid-sized manufacturer, I've learned that the questions answered in a product brochure are never the ones you ask in the supply closet. So here’s a list of real questions from my team. No marketing fluff.

1. Is Avient just a distributor, or do they actually make the stuff?

They manufacture it. They're a specialty materials company, not just a middleman. Their core is compounding thermoplastic elastomers (TPEs) and engineering plastics, plus colorants and masterbatches. But their strength isn't any single product—it's the breadth of their portfolio. For us, that meant one supplier could handle our TPE gaskets, our PP housings, and our PU overmolds. That alone saves us a ton of administrative overhead (seriously, cutting vendor management time by maybe 40% is a no-brainer for a small team).

2. We're comparing TPE suppliers. Why wouldn't we just go with the lowest price?

Because the bottom line is rarely just the price per kilo. I learned this the hard way. In Q3 2022, I greenlit a "budget" TPE supplier because they were 18% cheaper than our existing vendor. The product failed during accelerated UV testing—that 'cheap' option resulted in a $4,200 redo when the part cracked. Avient isn't always the cheapest, but their TPEs have consistent Shore hardness and processing properties. In my cost tracking system, a reliable material that runs without downtime is way more valuable than a marginal upfront saving. It's a ballpark of 10-15% higher unit cost, for a 30% reduction in scrap. That math works.

3. Polypropylene plastic—is it toxic? I've heard conflicting stories.

This is a super common question in our R&D meetings. Let's be direct: polypropylene (PP) is generally considered one of the safer thermoplastics for food contact and medical use. It's not toxic in its solid state, and it doesn't leach the same nasties as some other plastics (like PVC or polycarbonate with BPA). However, the additive package matters. That's where a supplier like Avient comes in—they can formulate a PP that meets specific migration limits for food packaging or medical devices. The resin itself is fine; it's the colorants, UV stabilizers, and slip agents that you need to spec carefully. My advice: if you're in a sensitive application, ask for a regulatory data sheet. If they hand it over without blinking, you're good.

4. Thermoplastic Polyurethane vs. Polyurethane—what's the actual difference?

This one trips up a lot of engineers. Here's the gist: Thermoplastic Polyurethane (TPU) is a melt-processable plastic; standard Polyurethane (PU) is a thermoset (it cures and can't be remelted). For practical purposes: TPU is for injection molding or extrusion (used in phone cases, tubing, seals). Thermoset PU is for foams, coatings, and adhesives.

If you're in a manufacturing environment and you need to make a part quickly, TPU is your friend. If you need a high-strength elastomer that can be bonded to metal, you might be looking at cast PU. Avient provides both—which is convenient. But don't assume you can substitute one for the other. I've seen a project fail because someone spec'd a TPU for a part that needed the thermal stability of a polyurethane. (That was a $9,000 lesson for R&D).

5. My product needs a specific color. Do I have to buy the base resin from one place and the colorant from another?

No, and honestly, that's a huge pain point Avient solves. They offer colorant systems that match any RAL or Pantone, and they can pre-color the compound. That's a game-changer for our production line—it eliminates mixing errors and reduces lead time. One PO, one vendor, one guaranteed color. In my experience (which is dealing with 15+ suppliers annually), this cuts inventory carrying costs by maybe 15-20%. Just make sure you request a color chip for approval before the production run. And get a signed off tolerance—those are the sorts of details that prevent a 'close enough' disaster.

6. We see 'sustainability' on your site. But is your recycled material actually any good?

It depends on the application. I'm somewhat skeptical of any blanket claims. For Avient, their reSound™ and maxxam™ REC lines use post-consumer or post-industrial recycled content. The material is good for non-structural parts—think trash bins, pallets, garden furniture. But here's the honest limitation: if you need high impact strength or UV stability for 10-year outdoor use, virgin material is still your best bet. I always test a pilot run before committing a whole SKU. It's not that the recycled content is bad; it's that the batch-to-batch variation is higher than virgin. For 80% of interior automotive parts, it's perfectly fine. For a load-bearing bracket, probably not.

7. What's the biggest hidden cost with Avient materials?

In my experience, it's not the material itself. It's the qualification and testing. If you're switching from a generic TPE to an Avient specialty grade, your tooling may need adjustments. They're a premium compounder, and their materials can have tighter tolerances. A slightly different shrinkage rate or viscosity can mean a mold modification. That's a one-time cost (circa $500-$2,000 if you need a mold change). My rule of thumb: budget 10% of the first order cost for requalification. Once that's done, the reliability pays for itself. I can only speak to our context—mid-volume manufacturing, around 20,000 units per year—but it's a factor that's often left out of the sales pitch.
