Compatibility M49/Polycarbonate/Polymethylmetacrylate

M49®, differently from traditional Acetate, is compatible with Polycarbonate:

- in the case PC/CA a sensitive increase in weight due to the migration of the utilized plasticizer;

- in the case PC/M49® a slight positive variance.

The compatibility is shown by the test 'on the ground' made on the finished frame.
The same test has been done using polymethylmetacrylate with substantially similar results.
