DuPont Plastics, Polymers & Resins DuPont™ Rynite® PET Thermoplastic Polyester Resin -- Rynite® 545 BK504 PET-GF45

Rynite® 545 BK504 is a 45% glass reinforced modified polyethylene terephthalate with good strength and stiffness, excellent dimensional stability and creep resistance.

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. Rynite® unites the best properties of reinforced polyethylene terephthalate (PET) with easier processability 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 and can be processed over a broad temperature range.

Due to its low water absorption, parts made with 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® polyethylene terephthalate 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.
