-- Method for producing surface-hardened PMMA films which are highly glossy on both sides free of gel bodies and can be manipulated in the film-insert-moulding method

摘要

The present invention relates to an impact resistant PMMA molding material according to DE 195 44 563 which is highly glossy, gel-free and processed into a surface hardening film which can be produced by the "integrated molding-film-decoration" process. will be. The molten material is formed by an extruder and fed through the flexible lip nozzle to the glazing rolls of the invention, which rolls are arranged to form a particularly high locking pressure in the roll slit. The smooth roll is cambered. Films are used for decorative surfaces of expensive thermoplastic molded parts.
