Dia 18 350mm Polyurethane PU Rod Bars

Dia 18 350mm Polyurethane PU Rod Bars   PU Polyether Rod (polyether polyurethane rod) is a thermosetting polyurethane rod synthesized with polyether polyol as soft segment, isocyanate (such as TDI, MDI) and chain extender as hard segment, and is formed by casting process. Compared with polyester polyurethane, the ether bond (-O-) in the molecular chain of polyether polyurethane gives it better hydrolysis resistance, low temperature toughness and resistance to microbial erosion, making it perform well in humid, cold or dynamic load environments. PU Polyether rods have a smooth and delicate surface (roughness Ra < 0.08μm) and uniform color (commonly brown, natural or black). The diameter range is usually 18mm to 350mm, and the length can be customized according to demand. According to the hardness grade and application requirements, it can be divided into high elasticity type (Shore A 70-90), high hardness type (Shore D 50-70) and high temperature resistant enhanced type (adding glass…
