Latest Patents

Harmen Z Coster holds a patent for the "Preparation of thermoformed plastics articles." This patent describes a method for creating moulded articles with uniform wall thickness through vacuum-forming or thermoforming. The process involves a composition that includes a base resin, which is a moulding grade resin with a continuous phase of a first copolymer of a styrenic monomer and an ethylenically unsaturated nitrile. Additionally, it incorporates a minor proportion of an additive resin, which is a second copolymer of a styrenic monomer and an ethylenically unsaturated nitrile with ultra high molecular weight. The forming operation is conducted at least 50 degrees Celsius above the glass transition temperature of the base resin and at a stress level of no more than 1 MPa. This innovative approach enhances the quality and performance of thermoformed plastic products.
