Keiper’s high-performance FLEXA flat belts are made of fully synthetic polyamide or polyester fabric and polyamide foil, with or without a suitable adhesion coating made of nitrile-butadiene rubber, depending on the wide range of possible power transmission and conveying applications.

• With a one-sided or two-sided coating of nitrile-butadiene rubber, highly resistant to abrasion and wear
• Different surface structures

• Power transmission belts
• Machine belts
• Tangential belts
• Spindle belts

+ Suitable for a large temperature range
+ High resistance to abrasion
+ Very good dynamic properties
+ Resistant to oils and acids
+ Outstanding anti-static properties of black NBR
- Gets brittle when exposed to UV light and ozone (only for limited outside use)
- Processing is work and energy intensive (vulcanization, hardening)
