Ethylene-chlorotrifluoroethylene copolymer - treated with ionising radiation after final shaping, to improve its high temp. properties

摘要

The resistance to soldering irons of 40-60 : 60-40 ethylene/chlorotrifluoroethylene copolymers as described in BE 748154 is improved by subjecting articles of the copolymer to an ionising radiation treatment after final shaping. The polymer may be e.g. in the form of fibre, film or esp. wire coverings. Treated polymer has considerably improved high temp. properties, e.g. resistance to soldering irons, when used as wire coverings.
