Plastic screws are used in a wide variety of applications and offer a number of benefits compared with metal products: They provide stability, yet at the same time are particularly lightweight and they do not rust. MISUMI Europa GmbH, based in Schwalbach (Germany), has expanded its portfolio of special plastic components for the European market.
The portfolio includes Philips-head tallow-drop screws and hexagon socket head screws made from glass-fibre-reinforced polyamide (RENY®), polyphenylene sulphide (PPS) and polyetheretherketone (PEEK). By expanding its portfolio, the Japanese specialist in mechanical standard, purchased and custom made parts is supplementing its range of connection components targeted at specific applications. As a result, the company is able to tap into additional areas of application with specific material requirements, for which conventional screw materials would not be suitable.
RENY® is made from polyamide MXD6 and crystalline engineering plastics reinforced with 50% glass fibre. RENY® sets itself apart from other engineering plastics through its high level of stability and elasticity; it also exhibits outstanding resistance against oil and heat.
PPS is a purely crystalline engineering plastic that also displays optimum thermal resistance. The physical properties of the material will not become impaired when subjected to high temperatures, even for prolonged periods. PPS is also particularly resistant to chemicals and impresses thanks to its mechanical and electrical insulating properties, in addition to its dimensional stability.
PEEK is a highly effective, high-performance, semi-crystalline engineering plastic. It offers the best chemical resistance of all the engineering plastics and can only be dissolved in concentrated sulphuric acid. The material also exhibits outstanding resistance to heat and hydrolysis, and it is abrasion and flame-resistant.
