Techno-maezawa in Anjo, Aichi Prefecture Japan. Design, produce and overhaul of resin liners for sand mixer.

UHMW-PE
UHMW has a molecular weight of 3.5～8.0 million, is much more greater than other ordinary high density polyethylene, which has a molecular weight of only ten of thousands to several hundred thousands Dalton. This contributes to its superb physical and chemical properties.
特性
◎Thickness is from 1mm
◎Light weight（Density is 0.97）
◎Wear and abrasion resistance
◎Anti-static electricity・・・・・long life for expendable parts
◎Dimensional stability under heat is 97 degrees
◎Notch impact strength is non-destruction

Our products are made by direct polymerization of nylon resin during casting. It is a typical engineering plastic that has a higher degree of crystallization than ordinary nylon resin, and features excellent mechanical strength, heat resistance, and creep properties.

特性
Our products can be applied to moving parts such as sliding boards, gears and rollers for steel equipment, solid parking lot parts, food machines, paper manufacturing machines, construction machines and Tooling machine.
