DuPont Rynite PET engineering thermoplastics are among the strongest and stiffest available. They are a prime candidate for the replacement of die-cast metals and thermosets in many demanding applications where stiffness, critical tolerances, and dielectric properties are key requirements.
This document serves as a product reference guide for DuPont Rynite® PET thermoplastic polyester resins. It highlights the material's status as one of the strongest and stiffest engineering resins available, suitable for replacing die-cast metals and thermosets in demanding applications requiring stiffness, critical tolerances, and dielectric properties. The guide compares Rynite® PET against PBT, thermosets, nylon, PPA, and metals, emphasizing advantages such as greater design flexibility, lighter weight, and lower processing costs.
| Material Type | Thermoplastic polyester resins |
|---|---|
| Recommended Drying Air Temperature | 110 – 135 °C (225 – 275 °F) |
| Recommended Drying Dew Point | -20 °C (0 °F) or lower |
| Maximum Mold Temperature for 0.75mm thickness | 110 °C (230 °F) |
Rynite PET excels with greater design flexibility, lighter weight, and corrosion resistance.
Dehumidified drying is recommended with an inlet air temperature of 110–135 °C and a dew point of -20 °C or lower.
