I’ve spent years in the trenches of the plastics and rubber industry, working with TPR (Thermoplastic Rubber) on everything from soft grips to shoe soles. One issue that drives manufacturers up the wall is glossy marks—those shiny, uneven patches that appear on TPR products after molding, ruining their look and feel. If you’ve ever pulled […]

I’ve been knee-deep in the plastics industry for nearly two decades, working with TPR (Thermoplastic Rubber) on everything from shoe soles to medical grips. One of the most frustrating issues I’ve seen pop up on injection molding lines is shrinkage—when your perfectly molded TPR part comes out smaller than expected, with sunken surfaces or distorted

I’ve spent over a decade in the plastics and rubber industry, working with materials like TPR (Thermoplastic Rubber) in everything from toy manufacturing to medical device production. One issue that pops up time and again is TPR parts or pellets sticking together, causing headaches for factory workers, warehouse managers, and quality control teams. If you’ve

As someone who’s been in the rubber and plastics industry for years, I know firsthand how frustrating it can be when materials get mixed up. TPE (Thermoplastic Elastomer) and TPR (Thermoplastic Rubber) are particularly tricky because they look similar and share some performance traits, often causing headaches for factories, procurement teams, and technicians. If you’ve

I’ve been elbow-deep in the plastics industry for over 20 years, and one challenge that keeps manufacturers up at night is the cost of recycling and re-pelletizing TPR (Thermoplastic Rubber). TPR’s versatility makes it a star in products like shoe soles and toys, but turning scrap or used TPR into high-quality pellets without breaking the

I’ve been in the plastics and rubber industry for nearly two decades, and one issue that keeps popping up—especially with TPR (Thermoplastic Rubber)—is color bleeding after spray painting. You’ve spent hours perfecting a TPR product, applied a vibrant coat of paint, and then, to your horror, the color starts migrating, leaving streaks or discoloration that

Having spent years knee-deep in the world of plastics processing, I’ve seen my fair share of production hiccups, and few are as maddening as TPR (Thermoplastic Rubber) pellets sticking together. You fire up the pelletizer, expecting neat, uniform granules, only to find a clumpy mess that looks like it’s been glued together. It’s a productivity

I’ve spent over a decade in the footwear manufacturing industry, working hands-on with TPR (Thermoplastic Rubber) materials, and I know how critical a smooth, glossy sole is to a shoe’s appeal. A rough or dull TPR sole can make even the most stylish shoe look cheap, and it’s a headache for manufacturers aiming for quality.

If you’ve ever stood by a twin-screw extruder, watching TPR (thermoplastic rubber) pellets come out hazy or opaque when you were hoping for crystal-clear clarity, you’re not alone. As someone who’s spent years tweaking formulations and fine-tuning extrusion lines in the rubber and plastics world, I’ve chased down this opacity issue more times than I

If you’ve ever worked with TPR (thermoplastic rubber), you know it’s a versatile material—soft, flexible, and perfect for everything from shoe soles to medical grips. But here’s the catch: getting two TPR parts to stick together reliably can feel like trying to glue water to sand. As someone who’s spent years tinkering in the rubber
