WORK IN PROGRESS for lowering overall emissions is needed,” explains Louis W. Martin, president, Addcomp North America Inc. (Rochester Hills, MI, US). “One approach we’ve explored is to use additional additives to capture and flash-off (via stripping agents) or permanently bind up (via adsorbents) residual VOCs left in the additives packaging after extrusion compounding The study demonstrates that source reduction and the use of newer stripping agents and adsorbents can reduce VOCs and fogging. of the additive masterbatch.” A study of five formulations (Table 1, p. 34) was conducted at Fraunhofer Institute for Chemical Technologies (Pfinztal, Germany), using D-LFT PP resin, an LGF 800 copolymer with a melt flow index (MFI) of 70 dg/min previously sold by Dow Automotive (Auburn Hills, MI, US) and now marketed by Styron (Berwyn, PA, US). It was combined with a 35% glass reinforcement (PPG 4588 glass rovings; chopped strands ≈25-50 mm going into the tool) from PPG Industries (Pittsburgh, PA, US) and additive systems from Addcomp. All five formulations used the same high-purity MAGPO coupling agent, dosed at 1 wt-%. Although the study did not use the newest PRIEX technology, this product represented proven technology and had a solid use history, making it a reasonable choice, given the other modifications made in the additives package. Each formulation also included a stabilization package that featured carbon black (for color) and an antioxidant stabilizer, dosed at 1.5 wt-%, although some formulations contained other additions to this baseline package. The control formulation (F1) used the standard stabilization package. F2 used an extra stabilizer, representing an older stripping-agent technology. F3 was a reduced-VOC masterbatch that relied on source reduction, that is, it contained purer components acquired from suppliers. F4 had a newer-generation stripping agent added to its stabilization package. And F5 featured an adsorbent that permanently binds with a variety of VOCs. In total, five masterbatch compounds were formulated, inline compounded into the base resin and then compression molded into test plaques. Standard specimens were cut from each plaque and subjected to ISO-standard VOC/fogging tests (VDA 278) to see if changes in chemistry affected emissions (Fig. 1, p. 35). Standard mechanical tests were performed to see if formulation changes affected other critical properties (Fig. 2, p. 35). Although all five formulations used the high-purity MAGPO coupling agent, researchers found that VOC emissions and fogging were further reduced vs. the control (F1) in F3, F4, and F5. F2 (older stripping agent) was slightly worse in VOCs and fogging than F4 (newer stripping agent). Interestingly, F3 (low-VOC masterbatch), which relied on source reduction alone, had better VOC emissions Flame Retardant Adhesive meets FAR standard 14 CFR 25.853(a) Two Part Epoxy EP90FR-V The Explosion Proof Bonder-- Redefined Works on 400 Hz • Superior electrical insulation • Ideal for potting and sealing • Passes vertical burn test Meets Class 1, Division 1 MIL-STD-810F/NEC Hackensack, NJ 07601 USA +1.201.343.8983 • main@masterbond.com www.masterbond.com www.WichiTech.com Call us for a personal demo: (800) 776-4277 ❖ 410/244-1966 Baltimore, Maryland 21201 USA 36 SEPTEMBER 2015 CompositesWorld
