General Info

Semitron® MP 370 Ceramic Filled Modified PEEK 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.

Key Properties

Exceptional machinability - very small holes and tight hole patterns are possible with sockets
Low internal stresses and no "soft center" problems associated with injection molded blanks
Strength and stiffness that exceed unfilled PEEK materials
Very low moisture absorption

Limitations

Poor Chemical Resistance to Halogens and Their Acids Including Bromine, Chlorine, Fluorine, HBr and HF

Applications

Precision Test Sockets for Small Hole and Tight Pattern Designs

Resin Trade Names

Manufacturer Trade Names

Semitron® MP 370

Boedeker Plastics, Inc. stocks & supplies plastic sheet, rod, tube, film and custom profiles and machine parts from these shapes that are produced from plastic resin. In many cases the manufacturer of the shape has their own product trade name. If your specification calls for a specific resin grade or manufacturer trade name, we can supply a shape made from that resin to meet your specification or suggest an equal. If you require a specific resin or brand it must be specified at the time of order.
