As a materials engineer who’s spent years tinkering with polymers in labs and factories, I’ve fielded my fair share of questions about tweaking material properties. One that pops up regularly is: “What kind of PS (polystyrene) should be added to TPR (Thermoplastic Rubber) to increase its hardness?” It’s a practical concern for anyone designing products […]

As someone who’s been navigating the world of polymers for years, I often find myself answering questions about materials that sound simple but hide a lot of complexity. One question I hear a lot is: “What kind of material is TPR?” It’s a great question, especially if you’re trying to figure out why TPR shows

Having worked in the materials industry for over a decade, I’ve often been asked questions that cut to the core of material selection, and one that keeps coming up is: “Are TPR and polyurethane the same type of material?” It’s a fair question, especially since both are flexible, versatile, and pop up in similar applications

Having spent years knee-deep in the world of rubber and plastics, I’ve seen firsthand how materials like TPR (Thermoplastic Rubber) can make or break a product’s lifespan. One question I get asked often, especially by those designing or manufacturing with TPR, is: “What stabilizers are used to prevent TPR from aging?” It’s a critical topic,

As someone who’s spent years working with rubber and plastic materials, I’ve fielded countless questions about their properties, and one that recently caught my attention is: “What happens when TPR material is burned?” It’s a practical concern, whether you’re curious about safety, disposal, or how TPR behaves in extreme conditions. Over the years, I’ve seen

As someone who has been immersed in the rubber and plastics industry for years, I often get asked about material choices, and one question that pops up frequently is: “Are TPR and TPE the same material?” Many people are confused about the differences between these two, especially when selecting products or designing applications, unsure if

A while back, I was helping a buddy pick out a new pair of running shoes when he pointed to a sneaker with a “TPR” sole and asked, “These soles look fancy—are they pricier than regular rubber?” I chuckled and told him it’s not that straightforward. Over the years in the footwear industry, I’ve heard

A few years back, I was part of a footwear project where our team spent hours debating whether to use TPU (Thermoplastic Polyurethane) or TPR (Thermoplastic Rubber) for a new line of shoe soles. The mold designer, clearly frustrated, warned us, “The shrinkage rates of these two materials are worlds apart—pick the wrong one, and

I still remember last summer when I bought a new pair of sneakers with TPR soles. On the first day out, they picked up a ton of dust and some mysterious stains. Staring at those grimy soles when I got home, I couldn’t help but wonder, “Are TPR soles just magnets for dirt?” I bet

As someone who’s spent years working with materials in industries ranging from footwear to industrial components, I often get questions about the properties of TPR (Thermoplastic Rubber). One query that’s come up recently is whether higher TPR hardness leads to higher viscosity. It’s a great question, especially for those diving into material selection for manufacturing
