Valox Super High Flow resins are glass and mineral-filled polybutylene terephthalates (PBTs).
They are highly viscous, so molders can make larger and more-detailed automotive parts with thinner walls. The resins also need 30% lower injection pressure than competing PBTs, which reduces cycle times and system costs by increasing the number of mold cavities that can be filled in a single shot. High dielectric strengths and chemical and heat resistance (–40 to 284°) make the PBTs candidates for underhood and electrical parts. They come in a range of glass reinforcement levels with flame-retardant and hydrostable grades available.
