The present invention describes a fiber material for use in mastic asphalt in roadbuilding for stabilizing the binder during transport, storage and incorporation, said fiber material being a macromolecular product including at least 95% of polyethylene terephthalate, the diameter of the individual fibers being .gtoreq.0.1 mm, the length to diameter ratio exceeding 5 on average, and the particle size distribution, measured as sieve passthrough as per the draft code of practice for the supply and testing of stabilizing materials in asphalt road construction in line with TP Min-StB Part 6.3.2, producing a proportion of at least 90% for the fractions .ltoreq.0.71 mm and at least 70% for the fractions .ltoreq.0.4 mm, and this product being manufactured by comminution from waste materials based on polyethylene terephthalate monofilaments.
摘要:
There is described a process for manufacturing shaped articles in which a fibrous material is mixed with an adhesive and maintained in a mold under pressure until the adhesive has set, which comprises using as the fibrous material a mixture of an essentially finely fibrous material based on synthetic fiber and of chopped monofilaments which confer the necessary hardness and stiffness on the shaped article to be manufactured, the adhesive content of the ready-produced shaped article being less than 10% by weight, based on the shaped article. The process makes it possible to manufacture shaped articles having a low adhesive content, which are repeatedly recyclable.

摘要:
The present invention refers to a barrier layer composition which is to be applied to at least one surface of a polyolefin body, in particular a polyolefin hollow body, wherein the composition contains: a) 40-70% by weight of one or more epoxide-containing metal oxide sols; b) 25-55% by weight of a binding agent polymer consisting of a terpolymer of maleic acid-maleic anhydride-vinyl monomers and/or a copolymer of maleic acid-vinyl monomers having a composition by mole of 50-75% of a vinyl monomer, 5-50% of maleic acid, and 0-20% of maleic anhydride; and c) 0.1-5% by weight of a catalyst on the basis of one or more tertiary amines.The hollow bodies coated with the barrier layer can be used particularly as storage containers for organic substances, in particular for organic solvents, fuels, mineral oils, pesticides, and other substances, for example liquids, the diffusion of which is to be inhibited or at least essentially reduced.
