New liquid crystal polymers target electrical, electronic applications

19-Apr-10
New Vectra G Series that features two new cost-competitive halogen-free liquid crystal polymer (LCP) grades has been introduced by Ticona Engineering Polymers. Vectra G141 and G441 are glass- and mineral-filled LCPs designed to help EE customers meet demanding lead-free soldering and halogen-free requirements, and steer clear of costly corrosion and maintenance issues. The series offers processing characteristics that avoid issues commonly encountered by electrical and electronic manufacturers that use flame-retardant, high-temperature nylons. The 35% glass-filled Vectra G141 and 35% mineral- and glass-filled Vectra G441 from Ticona are halogen-free, inherently flame resistant without additives, V-0 to 0.15 mm (UL listing expected May 2010), potential drop-in solutions for small FR, HT nylon parts. Both grades target the electrical and electronic markets, which typically require excellent dimensional stability in thin-wall parts, even at higher temperatures - more than 260C-where existing flame-retardant (FR) polymers struggle. They are designed to outperform traditional FR, high-temperature (HT) polyamides (nylons) and thermoplastic polyesters (PBT) that require lead-free soldering resistance.
