빅트렉스 XPI™ 150 폴리머

VICTREX XPI™ 150 polymer is a high-performance PolyEtherEtherKetone (PEEK), semi crystalline thermoplastic material, in granule feedstock format primarily for wire extrusion processing.

Winding wire insulation for electric motor applications requires good mechanical and electrical performance across a range of temperatures and potentially chemically aggressive environments. VICTREX XPI™ 150 polymer can meet many of these requirements such as (where specific properties are quantified in the below table);
• Long-term thermal stability in high electric field strength rotating machines
• Extruded coating provides superior electrical performance with reduced number of faults per wire length vs. enamelled equivalents
• Good ductility for demanding wire forming & resistance to thermal cycling / conductor expansion
• Excellent wear resistance
• Mechanical strength and dimensional stability
• Excellent chemical resistance to a broad range of ATF, oils and cooling fluids

Actual property values are highly dependent on part geometry, mould configuration and processing conditions. Properties may also differ for along flow and across flow directions.
