New Crastin® Offering For Electric and Hybrid-Electric Vehicle Connectors

Fully-coloured, compounded resins for high-voltage EV/HEV connectors now available

Geneva, 15 October, 2018 – DuPont Transportation & Advanced Polymers, a newly formed business segment within DowDuPont’s Specialty Products Division, is introducing Crastin® thermoplastic PBT polyester resins for applications in the fast growing electric/hybrid-electric vehicle market.

“We’re delighted to introduce these new fully-colour-compounded products that meet automotive OEM safety requirements to clearly indicate HV components in orange for use in hybrid, plug-in and battery (HV, PEV, BEV) electric vehicles,” said Joe Read, marketing manager EMEA at DuPont T&AP. “What’s more, the grades offer best-in-class CTI performance (600V) frequently requested for these demanding parts. There are benefits for moulders as well, including increased productivity and long-term reliability.”

Two new grades in the Crastin® family of resins are ideal for high-voltage connectors. Benefits include:

Crastin® FR684NH1 OR162 – 25% glass-reinforced, flame-retardant, non-halogenated, high-flow PBT in laser markable orange

·         Long-term reliability: component and orange colour stability at elevated temperatures

·         Increased safety: stable dielectric strength over temperature and meets UL94 V0 flame-retardance                    standard

·         Miniaturization: enabled by maximum tracking index (CTI 600V)

·         Complex shapes: high-flow capability allowing thinner walls, design flexibility and size reduction                          (miniaturization)

·         Design flexibility: demonstrates high elongation at break and good balance of mechanical properties

·         Increased productivity: of fully-compounded orange components made possible by robust processing              with minimum outgassing and corrosion through wider processing window versus competitive                              non-halogenated, flame-retardant PBT resins

·         Easy part traceability: UV laser marking (355nm)

Crastin® HR5330HFS OR516 – 30% glass-reinforced, hydrolysis-resistant, high- flow PBT in laser-markable orange

·         Long-term reliability: component and orange colour stability at elevated temperatures    

·         Performance in harsh environments: enabled by best-in-class hydrolysis resistance (HR)

·         Increased safety: exhibits stable dielectric strength over temperature

·         Miniaturization and design flexibility: due to maximum tracking index (CTI 600V) and high flow

·         Increased productivity: of fully-compounded orange components made possible by robust processing              with wider processing window and minimum outgassing versus competitive PBT HR resins,                                  and best-in-class melt stability suitable for hot runner systems

·         Easy part traceability: UV laser marking (355nm)
