Spoilage at the thermoforming of layered materials

Abstract

Steady growth of plastics industry necessitates the disposal of waste products from them. More and more manufacturers seek to include recycled materials and their technological waste in polimers compositions. Blending polymeric materials commonly used in the preparation of thermoformed articles from sheets of thermoplastics. Thermoforming process is cost effective, as it requires a significant investment in tooling in the manufacture of small batches of parts. In this study we investigated species discard practical use products, namely bath made by a combination of methods of thermoforming and contact molding coextruded sheets of ABS plastic with polymethylmethacrylate. Results of the study showed the veracity of the submitted samples assumption that as a raw material in the manufacture of sheets usedrecycled materials, which led to marriage in the finished product.
