wiper Edge™ EX | Bando Chemical Co.

Features

Sealing blades are made of a special polyurethane sliding part that provides coolant resistance (swelling resistance), a low coefficient of friction, and abrasion resistance.
Unlike rubber wiper blades, this adhesive-fixed design eliminates the need for molds, allowing for free design flexibility.

Coolant resistance

Immersion results with oil-based coolant (50°C)
Weight increase rate
	Soaking time
Equivalent properties to NBR for oil-based coolants

Immersion results with aqueous coolant (50°C)
Weight increase rate
	Soaking time
Equivalent properties to H-NBR for water-based coolants

*Swelling may occur depending on the type of liquid. Please contact us for details.

Comparison of coefficient of friction with rubber wiper (NBR)

Static friction

coefficient

Slippery edges are improved by including low-friction materials on sliding surfaces

Comparison of abrasion resistance with rubber wiper (NBR)

　　　　　　　　soft scuff marks

(1) NBR

(2) Wiper Edge EX

Wiper Edge EX is 10 times more abrasion-resistant than rubber wiper (NBR).
