CLEVELAND – October 31, 2018 – At MD&M Minneapolis today, PolyOne Corporation announced that Trilliant™ HC material outperforms FR PC/ABS after exposure to harsh disinfectants, according to tensile strength stress tests performed by an independent A2LA-accredited lab. Testing results show that Trilliant HC 2020 retains higher tensile strength than common FR PC/ABS materials after seven-day exposure to typical disinfectants. Developed as a drop-in replacement for FR PC/ABS, this innovative Trilliant HC formulation was recently used successfully by a medical device OEM seeking to improve resistance to cracking and brittleness for its housings.

Solvent Solvents soften surfaces of plastic (plastic must be soluble)—best for amorphous or low crystalline plastics, such as ABS, acrylic, cellulosic, PC, PS, PPO, and vinyls. Venting Guidelines by Resin • PC: .001"–.002" depth & .250" width • PC/PSU: .002"–.003" depth & .250" width • PES: .003"–.004" depth & .250" width • PEI: .001"–.003" depth & .250" width • PP: .001"–.002" depth & .250" width • ABS: .0015"–.0025" depth & .250" width • PEEK: .002"–.004" depth & .250" width FIGURE 40 - Venting Guidelines Vent Groove Vent Land Vent FIGURE 44 - Venting guidelines FIGURE 43 - Venting areas 20 Gravi-Tech CHAPTER 5 | PROCESS OPTIMIZATION Process optimization ensures a quality process and minimizes cycle time.

Specialized chemistries enable TPEs to adhere to many different plastic substrates, including PP, polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), PC/ABS, copolyester, polyamide, and polystyrene.

Pigment concentrates (PCs) A PC system uses pigment concentrates and base to create color. The PC/Base system was the first type of ink-mixing system ever released and is designed for maximum versatility.

To support the transition to molded-in-color (MIC) parts, the customer specified Avient’s metallic-effect Smartbatch™ FX concentrates for two PC/ABS side panels on the center console of a compact SUV.
