On the other hand, Somalite W is a molded material made from ultra-high molecular weight polyethylene (UHMW-PE), exhibiting extremely high values in properties such as wear resistance, impact resistance, low-temperature resistance, and stress cracking resistance, with applications including bearings and gears. Additionally, Dainichi Seikan also offers a more affordable lineup called Delight POM (an engineering plastic material made from acetal resin copolymer). *Please check the introduction page for Delight POM as well. Myojo Electric provides one-stop solutions from material selection and procurement of thermosetting resins, including glass epoxy, and thermoplastic resins to various processing methods such as cutting, molding, polishing, bending, and bonding. If you have any questions or inquiries, please feel free to consult with us.
