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.

The focus for this study was to develop thermoplastic elastomer compounds that would overmold onto substrates made from Nylon (PA), Polycarbonate (PC), Acrylonitrile-butadiene-styrene (ABS), and PC/ABS alloys

PC or PA also recommended Regrind 1.

Specific Versaflex OM grades have been specially formulated to bond to PC, ABS, nylon 6/6, PC/ABS, and PPO. The Versollan™ OM series are TPU alloys specifically designed for thin-wall overmolding (both insert and two-shot molding) onto PC, ABS, and PC/ABS substrates.

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.
