摘要:
The invention relates to a film membrane which has excellent weathering resistance and high permeability to thermal insolation, and is an effective barrier to thermal radiation emitted from the ground and has high mechanical strength, and also to a process for the production of the film membrane. The properties are achieved via a composite of a base film of thermoplastic and an outer layer of poly(meth)acrylate. The adhesion is achieved via copolymers with polar character. One or more layers of the plastics moulding may also have been equipped with flame retardants.

The invention relates to a novel UV-protective and weather-resistant package for surface protecting films for polyvinyl chloride window profiles made of poly(meth)acrylate. Matrix plastics having great molecular weights are used in order to obtain great weather resistance of the surface protecting films.

摘要:
A transparent plastic foil with improved weathering resistance and increased intrinsic stability is provided. The foil contains a) poly(meth)acrylate and polyvinylidene fluoride in a ratio of from 1:0.01 to 1:0.5 (w/w); and b) a mixture containing a UV stabilizer and a UV absorber. Use of the foil as a protective coating is also included.
