Polyurethane Molding
Polyurethane stands out as a versatile material prized for its dual flexibility and rigidity, making it indispensable in memory foam products. Its utility extends to solid plastic forms, polyurethane rods, urethane wheels, bushings, and sheets. Renowned for high performance, polyurethane moldings surpass plastic in durability and outshine rubber in impact resistance. They boast elastic memory, noise reduction, and resistance to heat and chemicals, embodying the best attributes of metal, rubber, and plastics.
Moreover, polyurethane can form robust adhesive bonds with most plastics and metals. Polyurethane molded parts typically require minimal to no finishing, streamlining the manufacturing process. This efficiency makes polyurethane the material of choice for producing a diverse range of products, including moldings, parts, bowling balls, urethane bumpers, belts, conveyor bushings, electrical potting compounds, press tool blocks, and pneumatic seals. Its applications span numerous industries such as athletic equipment, engineering, manufacturing, industrial, food processing, automotive, and construction. Discover the transformative potential of polyurethane molding.
Molded polyurethane, also known as urethane and occasionally urethane rubber, is a polymer that has properties of both plastic and rubber, which make it one the most sought-after materials in the manufacturing industry. Primarily, molded urethane has application in manufacturing flexible, rigid memory, and structural foam; however, their application as a solid plastic is also important.
Benefits of Polyurethane Molding
Polyurethane molding is a highly advantageous process. We recommend exploring it for a number of reasons. Let’s go over them.
Excellent Results
Polyurethane molding, as a process, offers the benefits of high accuracy, diverse part size capabilities, a fast turn-around and the ability to form parts with undercuts as well as parts without drafts.
Superior to Rubber
Polyurethane moldings have higher abrasion, cut, tear, oil, oxygen, ozone and radiation resistance than rubber parts. They also have greater load bearing ability, a broader hardness range, and better colorability.
Superior to Metal
Urethane mold parts have shown superior wear resistance to some kinds of steel products. Also, as compared to metal products in general, polyurethane parts have better noise reduction and resilience, greater abrasion, corrosion and impact resistance, and more flexibility.
Better than Regular Plastic
Molded urethane parts serve better than regular plastic parts in many applications. This is because they have higher impact resistance, temperature resistance, cold flow resistance, radiation resistance, and abrasion resistance. In addition, they have better elastic memory, noise reduction capabilities, and resiliency than plastic parts.
A Better Raw Material
Polyurethane is lightweight, easily moldable, non-conductive and non-sparking. In addition, polyurethane exhibits excellent adhesion and can easily form strong bonds with most metals and plastics. Plus, polyurethane has thick section molding and low-pressure tooling capabilities and a cast-able nature.
Versatile Process
Polyurethane molding is a versatile process. For example, manufacturers can easily create foams without external energy, but if they so choose, they also can mold parts using heat. In other words, they can conduct custom mold parts to exhibit virtually any physical or chemical property.
