Special Features•OR-300 grade has excellent resistance tothe toughest oilapplication such as oil-treated coal,petroleum based oils.
•OORR--220000grade hassuperior oil resistanceto various kinds of animal and vegetableoil with severe cold temperature up to - 45℃(50℉).
•OR-100 grade is to resist Moderate Oil Resistant operations like wood chips, linseed, cottonseed and whole soybeans where staticconductivity is needed.
•HTN grade is recommended for conveying hot asphaltwith temperature up to175℃(350℉) whereboth oil & heat resistance are required.
The cover rubberis especiallycompounded forthe applicationsrequiring resistance to oils.It has outstandingabrasion, ozoneand weatherresistance.This conveyorbelt isrecommendedfor the conveyorlines causingswelling andsponginess byoils.
