Semitron MP 370
Product Specifications
Semitron - Grey - Extruded Grade
DESCRIPTION
Semitron MP 370 offers more choices in the design and manufacture of precision test sockets for the semiconductor
manufacture industry. While maintaining the same excellent moisture absorption and high thermal resistance of PEEK, Semitron
MP 370 provides greater strength and dimensional stability. This custom formulation allows finer and cleaner detail due to it's
excellent machinability.
FEATURES
FORMS
• Very low moisture absorption
• Plate
• Exceptional machinability very small holes and tight
hole patterns are possible
• Strength and stiffness that
exceed unfilled PEEK
materials
• Low internal stresses and no
soft center problems
associated with injection
molded blanks
