German distributor Biesterfeld will be marketing Solvay's sulfone high performance polymers in UK and Ireland effective April 2019.
The portfolio includes polymers branded Udel PSU, Radel PPSU and Veradel PESU, Biesterfeld announced 31 Jan.
Udel PSU is a polysufone characterised by high-strength and transparency. According to Biesterfeld, the material offers higher heat resistance and better hydrolytic stability compared to polycarbonate (PC). The plastic is often used in medical devices that require durability, impact resistance and transparency. PSU can also be used in fittings, valves and other components in pressurised hot water systems, as it retains its strong mechanical properties when exposed to steam and other sterilisation techniques.
Radel PPSU (polyphenylsulfone) is another sulfone polymer well-suited for components in pressurised hot water systems and medical devices that undergo repeated steam sterilisation. The material has “exceptional impact strength” in addition to chemical resistance. It can be steam sterilised over 1000 cycles without significant loss of properties.
Veradel PESU (polyethersulfone) is especially suitable for food service applications and electronic components, such as vehicle lighting and testing devices, due to its flame-retardant properties. This product has good chemical resistance, high rigidity and excellent heat resistance.
Biesterfeld already distributes Solvay's sulfone polymers in many parts of Europe since 1998, according to Andreas Savvides, channel partners manager at Solvay Speciality Polymers.
