The Centre for Innovation in Polymer Engineering (PIEP) is a private association, with a technological and scientific matrix and a business management model.

Founded on December 13, 2000, by the initiative of the industry and in collaboration with the Department of Polymer Engineering of the University of Minho (DEP-UM) and the Support Institute for Small and Medium Enterprises and Innovation (IAPMEI), PIEP intends to provide a prompt response in the delivery of products and services, oriented to the R&D+i needs of companies in the plastics and related sectors, through innovation activities, technology transfer, technical-scientific consultancy, and services provision.

In general, PIEP acts in terms of the provision of testing services and failure analysis, the development of new materials and products, processing technologies, and productive tools, based on the promotion of the principles of sustainable development (Circular Economy and Environment).

PIEP also contributes to training, supporting the development of human resources with capacity and experience in industrial innovation in the field of polymer engineering.
