YUKOSYOKAI CO., LTD.｜Gore® Hyper-Shee® Gasket

Hyper-Sheet Gasket is a sheet-type sealing material with flexible and strong fiber structure, made from expanded PTFE which has various benefits and a wide range of applications.
Compared to conventional PTFE sheet, Goretex(R) Hyper sheet, extremely soft, can be easily cut with a cutter knife.
It conforms to rough surfaces or real-world flange conditions, yet compressoin into a very tough gasket that makes a tight, long lasting seal.
The sheet is available to fit flanges of any size (maximum:1,500mm×3,000mm) and configuration.
Made from 100% PTFE; Excellent chemical and heat resistance, and no pollution. It performs reliable sealing under highly corrosive environments or under the conditions which need to maintain high level of cleanliness like the food industry.
