Company insight
Leading producer of Radel PPSU semi-finished shapes
Westlake Plastics offers Radel PPSU in its lineup of semi-finished high-performance thermoplastic products that serve into the life sciences market. Radel PPSU is a registered trademark of Solvay.
adel polyphenylsulfone (PPSU) is an amorphous transparent high- performance thermoplastic, known for its high heat resistance (HDT of 207°C or 405°F), extreme toughness and impact strength, and high flexural and tensile strength. Radel also offers excellent hydrolytic stability and good resistance to a broad range of chemicals. In its natural form, it is transparent with an amber tint. As a result, it is readily colourable in a variety of transparent tints and opaque colours.
R Design benefits
Radels light weight and outstanding mechanical and thermal property profile combined with its hydrolytic stability and chemical resistance make it well suited for a variety of medical devices and life science applications. It is resistant to stress cracking and degradation from a range of hospital disinfectants, and can be sterilised using all common methods including steam autoclaving, gamma irradiation, ethylene oxide (EtO) and vaporised hydrogen peroxide. Radel PPSU is ISO 10993 compliant and is suitable for limited exposure medical device applications having less than 24 hours contact with bodily fluids and tissue. These features give engineers more design freedom and flexibility.
Applications
Medical device applications such as sterilisation cases, surgical instruments
and tools, orthopaedic joint replacement sizing trials and dental tools all benefit from Radel’s ability to be repeatedly steam sterilised.
Biomedical and pharmaceutical applications such as filtration devices, valve and manifold bodies and pump housings are well suited to made from Radel due to its chemical resistance, hydrolytic stability and high strength.
A trusted partnership Westlake Plastics takes a collaborative approach to working with customers and brings to the table an outstanding knowledge of thermoplastic materials, manufacturing processes and designing with thermoplastics. As an ISO 9001 and ISO 13485 registered company, it is committed to quality and continuous improvement. It is a customer focused organisation and values customer feedback.
