HiPET enhanced polyester resins comprise a new family of thermoplastic polyester alloys that exhibit a unique combination of high impact strength and high elongation properties. These polymers have a notched Izod impact of 12-15 ft.-lb./in. tensile strength over 5,000 psi and elongation of 250% to 500%. HiPET polyesters are ductile in response to stress and can be made very rigid with reinforcements. These are super tough materials with excellent solvent resistance and very good low temperature toughness.
The Table below contains a summary of the properties of HiPET 1000 compared with other engineering plastics. As shown by these data HiPET polyester offers an extremely attractive balance of cost and performance compared with these widely used engineering materials.
HiPET polyester resins are opaque white in their natural state and are easily colored for most any appearance application.
HiPET polyesters have uses in couplings, shoe soles, motor mounts, automotive boots, tubing, seals, hot combs, machine housings, tool jackets, ax handles, and other applications requiring toughness.

General Processing Conditions: For extrusion typical barrel temperatures should be 500-520 deg. F. Die temperatures may be as high as 590 deg. F. Injection molding barrel temperatures will typically be 480-510 deg. F. Mold temperatures will typically be 150-200 deg. F. Polymer should be dried for 4 hours at 220 deg. F before processing.
