The advantages of PU versus other materials in the industry are: The possibilities of polyurethane are almost infinite. High-quality custom-made polyurethane products. Almost anything is possible. Water clear, non-yellowing urethane casting resins for applications demanding optically clear castings, Vacuum or pressure casting is recommended for bubble-free castings, Can be colored with PolyColor Dyes to create clear, colored parts, Poly 15-Series plastics can be used to make thermoplastic-like, stone-like or pewter-looking parts, Certain options in this series can be thickened with PolyFiber II for making lightweight mold shells or hollow/lay-up castings, This series includes Poly 15-3 and Poly 15-3X Liquid Plastics, which feature the least amount of shrinkage in castings compared to other Polytek. Think of hard, soft, flexible, tough, light materials and different colours. Polytek will be closed on Thursday, November 26th and Friday, November 27th in observance of Thanksgiving. And that polyurethane offers many advantages over other materials in the industry. 610-559-8620 | 800-858-5990 They are made of polyurethane, which combines the shock-absorbing qualities of rubber with the tear resistance of plastic. With this Challenge innovative startups, entrepreneurs and students were challenged to come up with solutions f. We excel in the production of custom-made plastic, rubber and polyurethane products. Our custom-made polyurethane products Hollow and solid products in all possible shapes. Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. View Technical Specificatons for all Polytek® Polyurethane Plastics. A hard rubber product? Without exaggeration: polyurethane products make our lives easier. Or like plastic. But what is PU, then? But that is not the case. Wipe away all excess finish from the rim and lid before replacing the lid to prevent air from entering … Polyurethane (or ‘PU’) is so versatile and flexible: it simply is confusing. If we put this in a table, it turns out that comparison remains difficult. A copolymer? Hardness is a dimensionless quantity. That makes a huge variety of properties possible. Polyurethane delivers excellent performance across a hardness range that spans from approximately athletic shoe sole (low hardness) to bowling ball (high hardness). But, if we still would want to compare PU with rubber and plastic, then we would have to study the full diversity of the material’s hardness. Polyurethane Rubber Tubes Use these tubes as jackets, seals, and insulation in areas where rubbing and scraping could cause wear on rubber. The material often looks and feels like rubber. Polytek ® 's two-part, room-temperature curing polyurethane plastics are available in varieties that can be poured, brushed or sprayed to create castings with unlimited versatility.. Polyurethane Accessories - Quick Reference Chart, Poly Plasti-Flex Urethane Casting Resin |, View All Urethane Resins | Quick Reference Chart, Polytek’s easiest-to-use and best-selling rigid casting plastics, Super low-viscosity systems designed for pouring, rotocasting & slush-casting, Fast demold times (as fast as 15 minutes), Options for pouring, rotocasting and slush casting, and spraying, A clear, light yellow/amber option is available, which is ideal for color casting or filler applications such as cold cast bronze. Often it is not. And actually no rubber either.

Urethane’s hardness has a wide range from very soft, like a gel bicycle seat (~25 Shore OO), to very hard, like a bowling ball (~75 Shore D). Converting between hardness scales is not recommended. Calling PU ‘polyurethane rubber’ or ‘polyurethane plastic’ is confusing. But the sweet spot for many of its performance properties occurs from 55 Shore A to 75 Shore D. This is where we tend to see the most potential for polyurethane. Polyurethane durometer, or hardness, is measured on various overlapping scales. 1984-2020 © Polytek® Development Corp. All Rights Reserved. Do you want to see what products we can make in polyurethane? Polytek®'s two-part, room-temperature curing polyurethane plastics are available in varieties that can be poured, brushed or sprayed to create castings with unlimited versatility. Why are the terms polyurethane rubber and polyurethane plastic so often used? If you want a soft rubber product, you can choose a cellular rubber or foam rubber. We can tailor the polyurethane’s hardness to fit your specific need. Tangible in different hardnesses. Because polyurethane is so much more versatile. Polyurethane casting plastics can be cast in silicone mold rubbers without any release agent, but require a release agent when cast in polyurethane rubber molds. It forces a conical-shaped indenter into the surface of the material and then measures the depth of the indentation, further describes the process for measuring hardness. We would like to tell you more about it in this Ridderflex knowledge blog. Polyurethane durometer is another way of saying polyurethane hardness. Think of hard, soft, flexible, tough, light materials and different colours. Polyurethane’s hardness range straddles typical rubber and plastic hardnesses. These products are part of our daily lives. Many applications – from shock absorbers to wheels to wear pads – take advantage of polyurethane’s unique combinations of performance and hardness. These plastics are separated into six different series, highlighted below. Polyurethane’s durometer is dependent on the specifics of the formulation. Visible in the endless colour options. But a plastic is a copolymer as well, isn’t it? These plastics are separated into six different series, highlighted below.
