According to SABIC Innovative Plastics, electrical and automotive part manufacturers now have many more choices when moulding thin-wall parts such as connectors and excess voltage cut-off switches. Super High Flow resins enable thinner-wall parts that accommodate more capabilities. They also speed up processing and cut costs while maintaining good mechanical and heat performances.
SABIC adds that by doubling the flow performance of traditional glass-filled PBT resins, Valox SHF resin grades offer several important benefits. These include thinner-wall parts and more-complex designs (part consolidation) than were previously possible. Reduced part stress also results in better dimensional stability and performance. Reduced system costs occur by eliminating short shots (scrap), minimizing tool maintenance due to lower injection pressure, and reducing the amount of resin required. Also, because Valox SHF resin can be processed at a lower temperature than conventional PBT resins, less energy for heating/cooling is needed. Cycle time can be reduced by up to 25 per cent due to faster injection rate and reduced cooling time, leading to more parts per minute.
