CSB has introduced over 50 types of plastic sleeve material in its EPB series, and is currently still testing nearly 100 materials that have not been formally introduced. Each material developed by CSB's materials engineers reflects customers' actual needs and is based on CSB's several decades of abrasion-resistant polymer material R&D experience. All new materials are the result of extensive laboratory testing and verification, and materials must pass nearly 100 different types of laboratory tests before they are provided to customers;
Among our many types of plastic sleeve materials, EPB is the best choice for general use, and will have a long service life when used in most ordinary situations. As for other materials, EPB3 emphasizes high strength and abrasion resistance, EPB4 can withstand temperatures of up to 200°C and is highly resistant to chemical corrosion, and EPB5 can withstand temperatures of up to 250°C; it is worth noting, however, that these materials will not be able to demonstrate their true worth when used at room temperature. EPB7, EPB13, and EPB15 are all highly abrasion-resistant materials with long service lives. Among them, EPB13 has long been a mainstay for the production of the sliding films of plastic linear bearings, and many plastic plain bearings made from EPB15 are still going strong after being in daily use for 12-16 hours in dusty situations such as escalator chains for many years.
While CSB certainly offers many special-purpose plastic sleeve materials, it should be explained that these special materials are only intended for use in special applications, and are not suitable for other situations. For instance, EPB9 conducting plastic sleeve material has been developed exclusively for use in dry friction conditions where static charges may be present. For its part, although EPB20 also has an anti-static function, it is intended for use in high-speed sleeves able to operate immersed in water. EPB24 was developed as a self-lubricating bearing material for use in automotive fuel systems, and is not intended to withstand dry friction.
Among the various types of high performance materials, CSB has also developed a number of materials with high performance-price ratios, including EPBH, EPB2D, and EPB3G. These materials are suitable for situations involving sustained static load or intermittent low-speed motion.
