GENERAL PROPERTIES
click to resize photo Semitron® MDS 100 was developed to offer a remarkable combination of high strength, low moisture absorption, high stiffness and the resulting dimensional stability. Its unique, proprietary polymer matrix makes it ideal for use in parts where fine machining and precise tolerances are critical. As a result, Semitron MSD-100 is an ideal choice for semiconductor test sockets, nests and fixtures in used in electrical test and packaging equipment.

With a Flexural Modulus (ASTM D790) in excess of 1,400,000 psi and extremely low moisture absorption (24 hr., ASTM D570) of .10%, Semitron MDS 100 delivers performance that solves engineering problems associated with uncontrolled application environments. Its low Coefficient of Linear Thermal Expansion (ASTM E831) of 1.1 x 10-5 also contributes to its remarkable stability. The Heat Deflection or softening temperature (ASTM D648) is 410° F (210° C)

Semitron® MDS 100 is  LIGHT GREY  in color and available in sheet or plates ranging in thicknesses from 1 mm to 6 mm (.04 to .236") in sheet sizes of 250 mm x 250 mm (9.84") and 500 mm x 500 mm (19.68"). Other thicknesses are possible.
