MIXED ESTER AND ITS USE AS A PARTING AGENT IN PLASTIC MOULDING MATERIALS

摘要

A mixed ester of a long-chain aliphatic monocarboxylic acid with 24 to 40 C atoms, an aliphatic bicarboxylic acid with 2 to 12 C atoms and an aliphatic polyol with 3 to 12 atoms and 3 to 6 OH groups exhibits a very high separating action as a parting agent in thermoplastic materials. It also provides great transparency, especially in glazing roller films.
