X-PET - Unaxially oriented high modulus and high strength PET and PBT

Summary
x-PET enables the production of thicker molded bodies by cross-linking the polymer by stretching it directly from the melt
Technology Benefits
Simple production
High-modulus
High-strength
Suitable for lightweight construction
Technology Application
For the first time thicker, high-modulus and high-strength components can be produced as fibers (e.g. panels and profiles).
The typical application is in the field of lightweight construction.
Detailed Technology Description
A process for the production of uniaxially oriented, high-modulus and high-strength PET (polyethylene terephthalate) or PBT (PBT = polybutylene terephthalate) profiles directly from the melt has been developed at the Technical University of Dortmund. Therefore PET or PBT is crosslinked in the extruder with PA (phthalic anhydride) and TGDDM (tetraglycidyl-diaminodiphenylmethane) and then stretched from the melt.
