PES polyethersulfone films
Our PES film is an amorphous, transparent and light amber coloured high performance thermoplastic and is the most heat resistant of all commercially available transparent thermoplastics. Its water absorption capacity is relatively high and, as with many other plastics, drying is essential before thermoforming. Polyethersulfone is not particularly resistant to fatigue and tends to stress cracking. Its thermal ageing resistance is good and its radiation resistance is adequate. In terms of its chemical resistance, polyethersulfone is not as good as PEEK, so stable solutions can be made with polyethersulfone if the right solvents are selected.
Application of PES film
PES is used in electrical and electronic components, medical equipment that requires repeated sterilisation and photographic accessories.
