String protection board customized part according to customer drawing or sample
Product Description
Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene,
(HMPE), it has extremely long chains.The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made.
UHMWPE face pads
UHMW PE is the strongest and toughest of all polyethylene grades for marine applications - even outlasting steel as a facing material, and many times better than timber facings. UHMW PE does not decay or rot, and is unaffected by marine borers. It is grain-free so will not splinter or crush, and can be cut, drilled and
machined with ease. Most UHMW PE is supplied as Black - not just because this is the most economic choice, but also because black is manufactured using a double sintering process which work hardens the UHMW PE to further increase its abrasion resistance.
UHMW PE is available in many other colors yellow, white, blue, green, red, grey or orange which can be used to make the fender system highly visible in poor weather or to demarcate zones along a berth. UHMW PE also comes in many thicknesses per project requirements and also can be provided in a re-processed grade for a more economical solution.
UHMW PE can also be supplied in stand-alone applications not related to rubber fenders, for sliding surfaces that do not require any energy absorption.
String protection board (Fender board )is a widely used industrial material with a wide range of applications. Firstly, in the mining industry and coal preparation plants, fenders are used to make equipment for processing liquids, solids, and solid-liquid mixtures, such as funnels, chutes, and flippers. The sliding parts of these equipment are equipped with fenders that provide excellent wear resistance. In the metallurgical industry and thermal power plants, it also plays an important role in ensuring the corrosion resistance of conveying equipment and ensuring the stable operation of the production process.
In the shipbuilding industry, fenders are indispensable components used in the design of lining plates inside ship cargo holds, ensuring the safe transportation of goods while resisting the wear and tear of the hull caused by the cabin environment. In addition, fenders are often used for the lining of large sliders, mining cars, and dump truck carriages to extend their service life and improve work efficiency. Whether in terms of wear resistance or corrosion resistance of equipment, fenders have demonstrated their outstanding value and performance, providing cost-effective solutions for various industries.
