When you're looking for the ultimate combination of stiffness, temperature performance, maximum dimensional stability, and a high-gloss finish in glass-reinforced resins, Rynite® PET thermoplastic polyester resin is the most cost-effective answer. It unites the best properties of reinforced polyethylene terephthalate (PET) with easier processibility to produce high-performance parts that can be molded conventionally.

Rynite® PET is formulated with a unique rapid crystallization system. It also has a 20°C heat deflection advantage over PBT. It can be processed over a broad temperature range.

And, because of its low water absorption, parts in Rynite® PET maintain their properties and dimensional stability. This makes it a prime candidate for the replacement of die-cast metals and thermosets in many demanding applications where stiffness, critical tolerances and exterior finish are key requirements. The outstanding flow characteristics of Rynite® PET allow it to fill complex, thin-walled molds with less injection pressure than is needed with other resins. This is a particularly important advantage with miniature parts.
