New glass filled Super High Flow resins to benefit electrical/electronic part designers

28-Jan-09

With an aim to aid electrical/electronic part designers to incorporate more functionality into smaller spaces and reduce system costs, SABIC Innovative Plastics has come up with a complete portfolio of glass filled Super High Flow Valox* SHF resins offering twice the flow length of standard glass filled polybutylene terephthalate (PBT). The company says the comprehensive PBT product family will provide electrical and automotive part manufacturers many choices when molding thin-wall parts such as connectors and excess voltage cut-off switches. The Valox SHF resin portfolio comprises both flame-retardant and non-flame-retardant grades; low warpage and hydrolytically stable grades. Glass fiber levels range from 15 to 40%. By doubling the flow performance of traditional glass-filled PBT resins, Valox SHF resin grades is set to make possible thinner-wall parts and more-complex designs (part consolidation) than were previously possible. In addition, it will result in reduced part stress, resulting in better dimensional stability and performance while reducing system costs by eliminating short shots (scrap), minimizing tool maintenance due to lower injection pressure, and reducing the amount of resin required. According to the company, since Valox SHF resin can be processed at a lower temperature than conventional PBT resins, less energy for heating/cooling is needed. Another significant benefit include reduction in cycle time by up to 25% due to faster injection rate and reduced cooling time, leading to more parts per min.
