Toray Products Aren't Just for 'Premium' Projects Anymore. Here's Why I Changed My Mind.
I'm a procurement manager at a mid-sized medical device manufacturer. I've managed our plastics budget—roughly $420,000 annually—for over 6 years. For most of that time, I had a hard rule: Toray resin was for high-spec, low-volume projects where failure wasn't an option. For everything else—like our standard polyethylene plastic tube stock—I'd go with a cheaper alternative.
I was wrong. Or at least, my rule became outdated sometime around Q2 2023.
I'm not saying Toray is cheap. I'm saying that my total-cost-of-ownership spreadsheet—which has gotten more detailed every year—started telling a different story. The 'premium' gap was narrowing, and I wasn't paying attention.
Let me explain why I've started specifying Toray products for more of our 'standard' applications, and why you might need to update your own procurement assumptions.
My 2022 View: Toray = Premium Price, Narrow Utility
Back in 2022, I had a pretty simple framework:
- Toray (toray resin): Used for complex injection-molded parts in diagnostic equipment. Needed high purity and thermal stability. Price was a pain, but justified.
- Standard Resins (including ABS, PET): Sourced from second-tier suppliers for our basic tubing, clamps, and housing. 'Good enough' was the target metric.
I'd look at a procurement request for polyethylene plastic tube and my first thought was always, "Toray? No way. Over-spec'd and over-priced." I'd compare the per-kg price and call it a day.
That was my blindspot. The per-kg price didn't tell the full story—not even close.
The Data That Changed My Mind
In late 2023, we had a quality issue with a batch of tubing. The material we used—from a supplier I'll call 'Supplier Q'—met our basic spec sheets, but the failure rate on our assembly line jumped to 4.2%. That doesn't sound huge, but for a sensitive medical fluid path component, it was a nightmare. Scrap, re-testing, and a delayed shipment to a client.
I did a deep dive. Over the course of a week, I built a side-by-side TCO comparison using an order we were planning for Q1 2024. The product was a standard polyethylene plastic tube for a non-sterile fluid transfer application. Here's what I found:
The 'Cheaper' Option (Supplier Q)
- Base Material Cost: $0.32 per meter
- Scrap Rate (historical): 2.8% on average
- Cost of Scrap per 10,000m order: $89.60 (material + labor to process rejects)
- Hidden Cost (line stoppages): ~$180 per incident (we had two in the last year)
- Total Estimated Cost: $3,589.60
The 'Premium' Option (Toray Resin)
- Base Material Cost: $0.43 per meter
- Scrap Rate (estimated based on first pilot): 0.4%
- Cost of Scrap per 10,000m order: $17.20
- Hidden Cost (line stoppages): $0 (no stoppages attributed to material in pilot run)
- Total Estimated Cost: $4,317.20
On the surface, Supplier Q was still cheaper by about $727. But that's where my old analysis would stop. Let me add the context my spreadsheet was missing.
"The 'cheap' option isn't just about the sticker price—it's about the total cost including your time spent managing issues, the risk of delays, and the potential need for redos."
The $727 gap disappeared when I factored in the engineering time to qualify the alternative material. The Toray resin was already approved for our spec. The Supplier Q batch? It technically passed, but we had to negotiate acceptable limits. That meeting cost us time. With Toray, I spent 15 minutes on the phone with their technical rep.
Suddenly, the 'premium' option wasn't just about being premium. It was about being predictable.
The Bigger Picture: Toray Products in Standard Applications
Now, I'm not saying you should use Toray for every piece of plastic you buy. That would be irresponsible budgeting. But I've changed my 'gate' for when I even consider them.
Where Toray resin now makes sense in my budget
- Any application where failure creates a cascade of cost (rework, scrap, slowed line). For standard tubing? Yes, if it's a high-throughput line.
- Specifications that are 'tight' but not extreme. If your ABS plastic part requires consistent color and shrinkage across batches, Toray's process control beats a generic supplier every time. That's not a luxury—it's a risk management tool.
- Lower volume but high-variety orders. With Toray, I can order a smaller lot size and still get consistent quality. With a cheaper supplier, the quality might vary more between batches, forcing me to order safety stock that I'll scrap.
Where I still don't use Toray
- Protective caps and low-impact packaging. If a failure doesn't matter, why pay for premium?
- Orders where true cost is driven by volume and accepted tolerance is extremely wide.
Addressing the Obvious Concern: 'Isn't This Just Supplier Propaganda?'
I get it. When I tell other procurement people this, I see the eyebrow raise. "You're saying Toray is actually cheaper?" No. I'm saying the risk-adjusted cost is often close enough that the decision shouldn't be purely about price per kg.
Honestly, my gut still says 'Toray = expensive.' It's a bias from years of buying on price alone. But my spreadsheet disagrees. Every time I run the TCO numbers for a standard part where quality variability has bitten us before, the Toray option looks better than I expect.
I'm not shilling for Toray. I'm just saying that my 2022 rule—'Toray is for premium projects only'—is a rule that cost me more than it saved me in 2023 and 2024. Sometimes the 'standard' material is the one with the most hidden costs.
Final Thought: Update Your Assumptions About Toray Products
What was best practice in 2020 may not apply in 2025. The fundamentals haven't changed—cost, quality, reliability—but the execution has transformed. For me, the fundamental question changed from 'Can I find something cheaper than Toray?' to 'What is the total cost of not using Toray for this specific application?'
The answer surprised me. It might surprise you too.
