KEIPER GMBH & CO. KG ANTRIEBS- U. TRANSPORTTECHNIK - power transmission and conveyor technology for industrial, commercial & craft applications

Polyester felt belt antistatic

KEIPER has an extensive range of flat belts, including high-performance flat belts, power transmission belts, folder-gluer belts, machine belts, tangential belts and conveying belts. For the perfect power transmission, conveying or control solution in any industrial sector. Keiper flat belts are designed to meet your specific requirements and applications, and, accordingly, they are made to size. Our flat belts are made of different traction layers and composite structures with different coatings such as nitrile-butadiene rubber, leather and surface structures. FLEXA With a polyamide or polyester reinforcement With a one-sided or two-sided coating of nitrile-butadiene rubber, highly resistant to abrasion and wear Different surface structures CROMA With a polyamide reinforcement With a one-sided or two-sided coating of chrome-split leather, highly resistant to abrasion and wear Butt leather belts Made of pure prestretched butt leather Rubber-and-fabric belts

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. Fitted with a polyamide or polyester reinforcement With a one-sided or two-sided coating of nitrile-butadiene rubber, highly resistant to abrasion and wear Different surface structures FLEXA belts can be used as: Power transmission belts Folder-gluer belts Machine belts Tangential belts Spindle belts Properties + 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)

Overview to the technical datas of KEIPER flat belt product range FLEXA

Keiper CROMA high-performance flat belts are made of fully synthetic polyamide foils, with a one-sided or two-sided adhesion coating of chrome-split leather. Fitted with a polyamide reinforcement. With a one-sided or two-sided coating of chrome-split leather, highly resistant to abrasion and wear. Chrome-split leather is used exclusively as a friction coating on power transmission belts as an alternative to nitrile-butadiene rubber (NBR). CROMA belts with a coating of chrome-split leather are perfect for power transmission applications where the rollers are considerably contaminated by oil and dirt. In view of its slightly porous surface, chrome-split leather is air and humidity permeable and absorbs moisture; thus, it retains friction. However, the coefficient of friction of leather is lower than that for nitrile-butadiene rubber and steadily decreases during operation.

Flat belt catalog

We have a complete range of polyurethane round belts for conveying and power transmission applications. PU round belts, extruded in open lengths, are homogeneous round profiles that can be welded for use as high-quality power transmission and conveying elements. Our stock mainly comprises solid profiles with a smooth or slightly roughened surface and hollow profiles for nipple connections. Several types have FDA/USDA approval and comply with EU Directive 2007/19/EC. Although we generally produce in open lengths, we can also produce all belts according to your specifications. Our round belts convey a wide range of products such as foodstuffs, glass, roof tiles, PC boards and many more. The standard range of round belts is rounded off with aramid, polyester or glass-fiber reinforcements. If an appropriate quantity is purchased, we also produce special types with PES or aramid reinforcements.

Hollow core belts for nipple connections when quick and easy installation is needed. Standard stock program: 75° Sh.A red, smooth 80° Sh.A sky-blue, smooth, FDA 85° Sh.A green, smooth Available diameters: 4.8mm - 15mm Available lengths: starting from 110mm Available hardness: 75° Sh.A – 85° Sh.D Temperature resistance: -30°C - +70°C Coefficient of friction: 0.3µ - 0.7µ

PU V-belts run individually or alongside one another and convey products on slightly ascending or descending conveying systems without allowing the products being transported, e.g. boxes, tiles, glass slabs, cardboard articles etc., to slip. In addition, PU V-belts are used for driving live roller conveyors. Standard stock program: 75° Sh.A red 80° Sh.A transparent, FDA 80° Sh.A sky-blue, FDA 85° Sh.A green 90° Sh.A white Profiles 6x4 / 8x5 / 10x6 / 13x8 / 17x11 / 22x14 Smooth or notched
