We are a world-class supplier of engineering raw materials. Our objective is to provide all our customers, from the small machine shop to the large multi-national corporation, a supply path that continuously delivers the highest levels of service, quality and value.
High-quality general-purpose engineering plastic materials; the chemical name is polyethylene. It’s available in a range of grades and forms to suit many applications.
The machining of polyethylene is uncomplicated provided the component tolerances allow for polyethylene’s relatively high coefficient of thermal expansion and tensile elongation values. Full machining instructions are available on request.
HD-PE has extremely good resistance to aqueous solutions of acids, alkalis and salts and also in alcohol and many solvents. Slight swelling may be caused by permanent contact with grease, oil and wax, but generally not enough to limit the use of the material. Aromatics and halogenated hydrocarbons will cause a reduction in useful working life. The material has no resistance to strong oxidising agents such as nitric or chromic acids, and halogens. The UHMWPE grade has even better chemical resistance; strong oxidising agents only cause surface swelling.
Commercial applications for this engineering material include:
We stock Polyethylene in round bar, round tube and hollow bar.
Our knowledgeable staff and resident metallurgists will be pleased to assist you further on any technical topic. Smiths Metal Centres Limited also boasts an in-house UKAS Accredited Testing Laboratory which is unique within the multi-metal and plastic stockholding sector. We believe this underlines our total commitment to quality and our ethos of being the complete service provider.
