ELECTRICAL CONDUCTIVE & ANTISTATIC COMPOUNDS Where static dissipation and controlled conductivity are critical, Colorant Chromatics functional compounds can meet the requirements of high- temperature applications, such as wire and cable and injection molded parts for the petroleum and chemical processing industries. Because of the thermal similarities of the resins they can also be used on PFA substrates. You have the responsibility to conduct full-scale end-product performance testing to determine suitability in your application, and you assume all risk and liability arising from your use of the information and/or use or handling of any product.

THERMA-TECH™ THERMALLY CONDUCTIVE FORMULATIONS combine the heat transfer and cooling capabilities of metals with the design freedom, weight reduction and cost advantages of thermoplastics. For example, leaders in the industry are collaborating with PolyOne to transition from metal to thermally conductive polymers. THERMA-TECH™ THERMALLY CONDUCTIVE FORMULATIONS have been shown to improve thermal conductivity by 50–100 times that of conventional plastics.

Stat-Tech™ TPE Static Dissipative & Electrically Conductive Thermoplastic Elastomers Stat-Tech™ TPEs are electrically conductive thermoplastic elastomers engineered to protect critical electronics from electrostatic discharge (ESD), and electromagnetic and radio frequency interference (EMI/RFI). They can offer the precise level of electrical conductivity required for your application and are available in a range of Shore hardness levels. Depending on your application’s performance needs, we can develop custom Stat-Tech TPE grades to provide anti-static properties, dissipation, conduction and EMI/RFI shielding.
