New Petra Endurance Enhanced glass-fibre reinforced thermoplastic polyester resins from Honeywell Plastics provide a balance of high fatigue strength and good surface appearance, a combination previously not available with compounds having high glass-reinforcement content.

Compared with other reinforced thermoplastic polyesters, the fatigue strength of the new Petra Endurance Enhanced grades typically is 10 to 50 times higher.

The Petra 7300 series is a post-consumer recycled PET grade, while the upcoming Petra 7500 series will be virgin polyester.

The new reinforced Petra grades have superior melt stability and high melt flow, permitting a much broader processing window compared with other highly reinforced polyesters. This makes the resins suitable for large parts and for thin-wall parts made in molds with small gates.

The high fatigue strength and good surface appearance possible with the Petra resins makes them ideal for molding chairs and arm rests.
