Chemically speaking, polyurethane finishing products are actual repeating chains of polymers that exposed to air become a super hard… We see or hear it quite often: a question for polyurethane rubber or polyurethane plastic. A hard rubber product? Almost anything is possible. The material often looks and feels like rubber. – Pick a 70 or 80 shore quality. Polyurethane’s hardness range straddles typical rubber and plastic hardnesses. From super low-viscosity, fast-setting resins to water-clear options, almost any color, size, shape, weight and appearance can be achieved by using these systems. But that is not the case. On Thursday the 29th of November, the winner of the Offshore Wind Innovation Challenge was announced: Ridderflex. If we put this in a table, it turns out that comparison remains difficult. But let’s keep it simple. Hardness is a dimensionless quantity. Therefore it is not surprising that people often ask for polyurethane rubber or polyurethane plastic. 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. And we actually would compromise PU. Think of hard, soft, flexible, tough, light materials and different colours. View Technical Specificatons for all Polytek® Polyurethane Plastics. Almost anything is possible. These products are part of our daily lives. Hardness is an indicator of a material’s modulus. That makes a huge variety of properties possible. Do you want to see what products we can make in polyurethane? Polyurethane is like a liquid plastic, often either a pure synthetic plastic or a blend with resin. Mixed up, as if the two words together form an expression. Without exaggeration: polyurethane products make our lives easier. 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 is a unique material that offers the elasticity of rubber combined with the toughness and durability of metal. 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). It is a copolymer based on polyols and isocyonates. 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. Then especially have a look at our polyurethane products. We would like to tell you more about it in this Ridderflex knowledge blog. And actually no rubber either. Polyurethane’s durometer is dependent on the specifics of the formulation. These plastics are separated into six different series, highlighted below. But hardness alone is not a good specifier of a polyurethane’s, Different polyurethane formulations can have the same hardness, yet have a very. And that polyurethane offers many advantages over other materials in the industry. Polytek will be closed on Thursday, November 26th and Friday, November 27th in observance of Thanksgiving. Polyurethane durometer is another way of saying polyurethane hardness. 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.. As its name implies, polyurethane is a plastic. Certainly black, gray or white products can put you on the wrong track. And neither with plastic. Usually it is a polymer. Polyurethane durometer, or hardness, is measured on various overlapping scales. Calling PU ‘polyurethane rubber’ or ‘polyurethane plastic’ is confusing. 1984-2020 © Polytek® Development Corp. All Rights Reserved. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available. 610-559-8620 | 800-858-5990 Often it is not. Most variation in polyurethane is visible and tangible. 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. 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. A low-density, slightly flexible plastic that can be used to make decorative trim, props or impact resistant parts. Tangible in different hardnesses. Polyurethane products can also be the solution for many technical problems. Polyurethane. Visible in the endless colour options. Polyurethane’s hardness range straddles typical rubber and plastic hardnesses. We can tailor the polyurethane’s hardness to fit your specific need. Hours: Monday-Friday | 8:30am - 4:30pm (EST). Polyurethane compared to rubber and plastics. Polargard® steel and canvas wearing sheet / lining product, Polyurethane and plastic products for the wind industry, Go to Polyurethane and plastic products for the wind industry, Gaskets and sealings for the wind industry, Go to Gaskets and sealings for the wind industry, Transport protection for the wind industry, Go to Transport protection for the wind industry, Gaskets and seals for the offshore industry, Go to Gaskets and seals for the offshore industry, Go to Polyurethane products for the offshore, Plastic products for the offshore industry, Go to Plastic products for the offshore industry, Ball valve seat assy: The summit of custom-made, RAAH International authorized distributor for Ridderflex in Asia Pacific, Canada and USA, Polyurethane rubber or plastic: terms are often mixed up, Absorbing sounds and noises instead of reverberating it, Extremely good performance in the 80A to 95A durometer range, No aging problems, such as drought cracks, Elastomeric memory (goes back in its original shape), Retains high impact resistance, even at high hardnesses. High-quality custom-made polyurethane products. Wipe away all excess finish from the rim and lid before replacing the lid to prevent air from entering … Many applications – from shock absorbers to wheels to wear pads – take advantage of polyurethane’s unique combinations of performance and hardness. If you choose a product in the plastic POM, than that product has only one hardness. We even dare to say that no other material in our product range is so flexible and versatile. Most variation in polyurethane is visible and tangible. But what is PU, then? They are made of polyurethane, which combines the shock-absorbing qualities of rubber with the tear resistance of plastic. (And we are so proud of it!). 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. Why are the terms polyurethane rubber and polyurethane plastic so often used? Polyurethane products can be made in 15 Shore A to 95 Shore A and in 40 Shore D to 77 Shore D. That is not possible with rubber. The material can be mixed in different proportions (‘systems’). It has the strength of plastic and the elasticity of rubber. Many applications – from shock absorbers to wheels to wear pads – take advantage of polyurethane’s unique combinations of performance and hardness. Visible in the endless colour options. Polyurethane Rubber Tubes Use these tubes as jackets, seals, and insulation in areas where rubbing and scraping could cause wear on rubber. Utilize available accessories to help achieve the desired look and feel. Think of car parts, shoe soles, paint, floors and wheels. Plastic Storage Sheds: Easy to install, durable and maintenance free buildings from Lifetime, Palram and Suncast! Polyurethane is actually not a (natural) rubber nor a plastic, but is something ‘in between’. Select a series below to view individual options within each series: A low-density, wood-like casting resin, which is easily carved, cut, sanded and drilled.
