3a ISO 75, 0.45 MPa, measured on annealed specimens.
4 ISO 179-1/1eU, unnotched, X-Y orientation, 23 °C.
A glass fiber reinforced polyester with high rigidity and strong dimensional stability. It holds its stiffness to well above 130°C and takes up little moisture, staying steady in humid and wet conditions. It resists fuels, oils, and dilute media, but strong bases attack the polyester.
