DUROPLASTS: phenolic based (PF) thermosetting plastics that harden during moulding due to irreversible polymerization.

TECHNOPOLYMERS: thermoplastic polymer materials for technical use in which the chemical composition of the molecular chain provides a wide range of mechanical, thermal, and technological properties. The transformation process is based on the melting and subsequent hardening by solidification of the material in the mould. The material itself has a low environmental impact because it can be recycled (reversible solidification).
