A World leader in PEEK fibres

Introduction

Polyetherketone (PAEK) polymers offer
a range of melt stable high temperature thermoplastics. These can generally
be melt-spun and drawn into a range of
semi-crystalline fibre products, which are  exceptionally thermally and
dimensionally stable.

PEEK is the most cost effective and
widely available of this family of polymers
as supplied by world leader Victrex®plc.

Fibre Properties

Zyex monofilaments, multifilaments
and staple fibres are produced on
specialist high temperature extrusion
equipment.  The degree of orientation
and crystallinity can be engineered to
meet specific requirements. 
Room temperature physical properties
are typically similar to polyester fibres.

Zyex products can normally be woven,
braided, knitted, twisted, needled with
conventional equipment and technology.

Textile finishing can require specialist
high temperature equipment depending
on the application.

Fibre Endurance

The real value of Zyex based products is encountered in use, giving longer life at
the extremes of temperature, steam
 or chemical exposure in a wide variety
of abrasive conditions.
