Matech Associates

Company Overview

MATECH ASSOCIATES was established in 1989 in Scranton, PA, as an independent commercial, for profit materials testing and product development laboratory, serving chemicals, plastics, man-made materials as well as electronic, semi-conductor and divergent industries in the U.S. for thermal, mechanical and electrical techniques. Testing protocol and specification services were also offered internationally.

 The organization has developed into a highly specialized materials consultancy for critical problem solving, training of laboratory personnel and group seminars in materials testing as well as electrical testing and evaluation, metrology, inspection, validation from the contact location given below.  

NOTE:  In 2001, a full line of thermal and electrical equipment plus laboratory furniture were donated to                  Wilkes University, Pennsylvania, by MATECH ASSOCIATES for  laboratory facilities for students.         

                 

Seminars offered

 Thermal Techniques in Chemistry and Materials Science.

  Electrical Techniques in Materials Characterization.

  Carbon-Vinyl reaction mechanism in cement matrix  (Durable Cement Formulation).

ITEMS OF INTEREST  - Today's Theme

Developing and understanding of the electrical testing requirements for materials in electrical and electronic applications:

 ♦Study of electrical properties of materials is based mainly on their dielectric state,

    intermediate between totally insulating and totally conducting characteristics.

 ♦This intermediate state is characterized in terms of a dimensionless pair of values

    called DIELECTRIC CONSTANT and DISSIPATION FACTOR.

 ♦Dielectric Constant is measured as a ratio of the parallel capacitance of the material

    under test to that of a dimensionally equivalent vacuum (air in practice).

 ♦Dissipation Factor is determined from the ratio of the resistive to the capacitive

    component of current that results from an applied frequency.

 ♦It is thus possible to evaluate the extent to which the material is able to maintain

    dielectric integrity within its designed limits.

  ♦Maximum Voltage Withstanding Capacity is expressed in terms of BREAKDOWN

     VOLTAGE which provides a safeguard value against dielectric failure.

 ♦Resistivity measurements afford judgement of the magnitude of resistance through

    the VOLUME and along SURFACE of the material.

 ♦Residual Conductivity or Insulation Resistance can be obtained from measurement of

    LEAKAGE CURRENT.

 ♦Interfacial Charge Crowding from DISCHARGE CURRENT measurement can account for

    low frequency AC losses.

 ♦STATIC DECAY testing by EIA-541 method can safeguard against damage of sensitive

    electronic materials by ELECTROSTATIC DISCHARGE.
