Ultrahigh molecular
weight polyethylene
Plastic Top chain
High shock resistance even at low temperatures
UHMWPE (Ultrahigh molecular weight polyethylene) was used for the first time as the link material of Plastic Block chain RSP80!
Taking advantage of the material's characteristics, it has been added to Plastic Block chain line-up as "Low-Temperature/Chemical-Resistant Series UPE".
Conforms to Japan's Food Sanitation Act thanks to its high shock resistance and superior chemical resistance. In addition, it has a potential to play active roles in various applications as materials approved by the FDA (U.S. Food and Drug Administration) are used.

Features of UPE Series (Low-Temperature/Chemical-Resistant Series)
High shock resistance even at low temperatures
Superb chemical resistance
Excellent wear resistance
High shock resistance even at low temperatures
UHMWPE (Ultrahigh molecular weight polyethylene) has high shock resistance and is not prone to scattering damaged, which reduces the risk of contamination caused by chain damage. Furthermore, this plastic block chain can be safely used for food conveyance as it's made of the material that conforms to Japan's Food Sanitation Act and the FDA (U.S. Food and Drug Administration).
