HIGH-TEMPERATURE PLASTICS | MATERIALS


The heat is on: plastics at high temperatures


Recent high-temperature plastic developments include new LCP grades, an electrical housing made from a bio-based polyamide and reusable wafer frames made from PPS


High temperature plastics – materials whose properties sit beyond those of other engineering polymers – are typically specified for their heat resistance, making them suitable for applications ranging from automotive to electronics. In one example, Meliori Polymer Engineering has begun using a polyphenylene sulphide (PPS) compound to make recyclable wafer frames for microchips at a new moulding facility. The company, based in Croatia, is making eight-inch wafer frames from a glass fibre- and mineral-filled grade. It says it is the only company that can manufacture, clean, ship and refurbish polymeric semiconductor support frames in Europe, from its 350 sq m facility in Croatia’s Šibenik Industrial Zone.


As well as an injection moulding cell from Sumitomo (SHI) Demag, the facility has a CNC machine to remove burrs from the eight-inch frames. There is also an automated washing and drying cell, a dedicated ISO Class 6 packaging cleanroom, and space to scale up and add two more production lines.

“Rather than single-use components that


generate excess waste, we wanted to ensure that the frames were moulded from a robust material that could be returned to our facility – where they are quality-checked, refurbished, cleaned, re- packed and shipped back to customers,” said co-founder Antonia Omazić.


Flexible PPS Toray Industries has developed a flexible polyphe- nylene sulfide (PPS), which it says offers high flame retardancy and heat resistance. The company believes it is the world’s first PPS


resin with these capabilities. The material is free of per- and poly- fluoroalkyl substances (PFAS), giving it a cost-reduction advantage over fluoropolymers. Prospective applications include fittings, fasteners, protective components, cooling pipes and electrical parts. It also helps to reduce the number of parts. The proliferation of electrified vehicles and data


centres has made components and electrical equipment parts more sophisticated and diverse.
