  • Flame retardants for polyamides - new developments and processing concerns
    Polyamides are now widely found in a variety of high performance plastics applications in automotive, electrical and electronic and other industrial markets, for instance. Flame retardants play an increasingly important role in extending the reach of polyamides in these areas. Jennifer Markarian examines some of the issues that need to be taken into account when making polyamide compounds flame retardant.

  • Mineral modifiers take on new roles
    Minerals used as fillers in plastic compounds have traditionally been used to reduce material costs by replacing a portion of the polymer with a less expensive material. However, nowadays many functional fillers or mineral modifiers are required to modify processing characteristics or finished part properties. Many are now also being used to reduce the level of more expensive additives such as pigments, flame retardants and impact modifiers. Jennifer Markarian reports on the changing face of fillers.
  • Strengthening compounds through fibre reinforcement
    Plastics continue to replace traditional materials such as metals in many high performance applications. Developments in fibre reinforcement for thermoplastics is helping to accelerate this trend. Jennifer Markarian reports on some of these developments and improvements in how fibres can be incorporated effectively into plastics.

PBT compounds offer twice the flow length

24 March 2009

SABIC Innovative Plastics has developed a complete range of glass-filled Super High Flow Valox SHF resins that offer twice the flow length of standard glass-filled polybutylene terephthalate (PBT).

According to SABIC Innovative Plasticselectrical 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.
