In this section, we take a closer look at some of the key technical aspects that define our materials and their performance. From understanding multiple MFI ranges and the importance of efficient demolding, to exploring the science behind gel formation, UV resistance, and our range of specialty compounded materials — each topic provides valuable insight into how our products are engineered for reliability, versatility, and innovation.
At EPAFLEX Americas, we understand that your products — and your manufacturing processes — have been refined over decades.
⏩ Fast-forward to today: you may be considering a new supplier or TPU grade (enter EPAFLEX Americas!),
but we also know that changing your process to suit a new material can be… challenging. 😅
That’s why we’ve designed many of our TPU grades to match your existing melt flow requirements,
allowing you to use them in a true “drop-in” fashion — no complicated retooling required.
EPAFLEX offers half a dozen different 85 Shore A polyether extrusion grades!
That’s right — six variations, each engineered to align with specific melt flow characteristics for seamless integration into your process.
If you’re looking to switch to a new TPU that matches your current melt flow,
just check your process data — temperature, weight, and grams/10 min —
and reach out to us today.
(Pro tip: melt flow data isn’t on the TDS — you’ll find it on your Certificate of Analysis!)
Change is constant — but EPAFLEX Americas makes it smooth, smart, and painless.
Injection molding thermoplastic polyurethane (TPU) has been around for decades —
a tried-and-true process used to make the everyday essentials we rely on:
👟 footwear, 📱 phone cases, 🚗 automotive parts, and more.
Despite its long history, demolding complex shapes and parts can still be tricky.
At EPAFLEX, we’ve seen some creative customer solutions —
like using manual exotic additives to help parts release faster from the mold.
💡 Smart idea… but not always practical or efficient.
That’s why we developed EPAMOULD, our tailored range of TPU products
engineered to deliver:
Our approach is technically optimized and commercially viable,
unlike other solutions that rely on complex polyol blends and drive up cost.
Don’t stay stuck with suboptimal molding grades.
➡️ Release yourself with EPAMOULD — available in both polyester and polyether chemistries.
Do you notice those tiny “unmelts” that ruin your product’s surface finish?
👉 An unsatisfactory look for you — and your customers.
There can be several reasons for the presence of gels in an extruded film or profile — and not all of them are entirely due to the TPU used.
⚙️ Sometimes, adjusting processing parameters helps…
but other times, the issue lies within the TPU itself.
To tackle this, EPAFLEX has developed a proprietary process for producing extrusion-grade TPU with exceptionally low gel levels.
✨ Bonus: this approach also allows us to deliver very tight and consistent melt flow ranges
(check out Show Me Something Interesting for details).
Our EPALINE products — available in both polyester and polyether chemistries — are designed to offer:
🔸 Guaranteed low gel level
🔸 Consistent performance
🔸 No batch selection or “cherry picking”
Just straight-up, top-quality extrusion-grade TPU production. Peri

Should’ve gone for SPF 10,000!
Just like we might turn beet-red and start to peel after too much sun,
your TPU can yellow and its physical properties can degrade over time.
Too bad there’s no sunscreen for TPU, right? 😅
As you probably know, additives can be introduced into TPU to resist yellowing and maintain mechanical integrity over time.
🌈 And yes — EPAFLEX has an entire suite of UV-resistant TPU grades ready to go right off the shelf!
Each formulation can be custom-tailored to handle different levels of UV exposure —
while also optimizing costs for your specific application.
A common approach? ☑️
Using masterbatches compounded into colorants —
a proven method, but one that requires careful control of let-down ratios from run to run.
If you’re looking for a custom UV resistance package that delivers:
🔸 Excellent long-term performance
🔸 Optimized cost efficiency
🔸 Consistent dosing in your production process

Because while aloe vera may soothe your sunburn,
it can’t help your TPU under the UV spotlight. 😎
Usually, this is the part where a manufacturer says:
“Not our problem — go talk to a compounder.”
😅 Cue confusion and suspense…
While we can’t be everything to everyone, we understand there are special applications where an extra compounding step can make all the difference.
We’re not compounders ourselves —
but hey, we know a guy! 😉
Need any of the following?
Whatever your goal, EPAFLEX has built strong partnerships with a trusted network of specialty compounders who can deliver the added functionality your project needs.
We’ll connect you with the right experts to bring your custom TPU solution to life.
