Multilayer material sheets containing unidirectional high performance fibers are obtained by a process which includes the steps of positioning the fibers in a parallel fashion, consolidation of the fibers to obtain a monolayer, stacking at least two monolayers such that the fiber direction in one monolayer is at an angle a to the direction of the fibers in an adjacent monolayer and fixation whereby the stack of at least two monolayers is subjected to a pressure and temperature treatment for a duration of a least 2 seconds, followed by cooling the stack under pressure to a temperature of 120 C. or lower. The multilayer material sheet has a reduced uptake of liquids.

Panel for forming a floor covering, where this panel has at least two layers of thermoplastic material, where the two layers substantially have a strewn and pressed granulate, where the respective layers enclose a glass fiber layer.

A method to produce a wear resistant foil, including providing a first foil including a first thermoplastic material, applying wear resistant particles on the first foil, applying a second foil including a second thermoplastic material on the first foil, and adhering the first foil and the second foil to each other to form a wear resistant foil.

An optical adhesive product and a process for manufacturing an optical adhesive product, laminated film ensembles, and laminated lenses. The optical adhesive product includes a glyoxal water solution that is pH adjusted for use as an optical adhesive that demonstrates a wet peel force strength above about 6 Newtons. A water based polymer, such as PVOH, may be added to the adhesive system. According to the process, the glyoxal adhesive system is manufactured and utilized to laminate TAC-PVA-TAC films together to form a polar film ensemble. The polar film ensemble is laminated to an optical substrate and in the case of an ophthalmic lens, surfaced, coated and edged. The optical adhesive product avoids film separation in the polar TAC-PAV-TAC film ensemble during edging.
