The automotive industry continues to find new ways to manufacture automobiles, especially the engine and electrical components that monitor and improve vehicle operations. The wiring used for these new electronics must be able to handle higher temperatures. This prompted Chroma Color Corp. (McHenry, IL) to engineer new products for customers with T1, T2 and T3 wire application needs. Chroma Color’s automotive products are designed for ISO 6722 85o, 105o and 125oC rated thermoplastic and cross-linked compounds.
Concentrates recommended for use with 85oC rated compounds have been formulated and verified to provide minimum thermal stability of 70 minutes at 200oC; those recommended for use with 105o and 125oC rated compounds have been formulated and verified to provide minimum thermal stability of 150 minutes at 200oC. Thermal stability is assessed using the dehydrochlorination (DHC) test.
Custom matched color concentrates are available upon request. Recommended letdown ratios are between 1 and 2%. The company encourages customers to perform tests in the specific compounds being used to determine the amount of concentrate needed to attain the desired color.
All products are compliant with various regulatory statutes.
