Thermoplastics Aim for Electronic Encapsulation.

Nine thermoplastic compounds for protecting sensitive electronic parts from moisture have been launched by RTP Co., Winona, Minn. RTP says its new electronic component encapsulation compounds have better dielectric and heat-dissipation properties than do the thermoset materials more commonly used in these applications. Other benefits are said to be reduced coefficient of thermal expansion and an improved hermeticity (i.e., sealability) of parts.

Matrix resins in the "([ec).sup.2]" line include PBT, PPS, PEEK, LCP, PPA (polyphthalamide from BP Amoco), thermoplastic polyimide, and syndiotactic polystyrene (SPS), a new crystalline polymer from Dow Plastics.

Blends of chopped glass and non-conductive minerals are used to control the compounds' coefficients of thermal expansion and ensure good adhesion of encapsulant. Colored and laser-markable versions are offered.
