Abstract :
A new thermoplastic dual-coextrusion-coating technique consisting of a soft thermoplastic rubber primary coating and a hard secondary coating has been proposed as an in-line coating system with fibre drawing. The use of a low linear-expansion-coefficient polymer as the hard secondary coating is a necessary condition for obtaining no microbending loss of the dual-coated fibres.
