摘要:
A composition useful in producing molded articles, fibers and sheet products is a mixture of from 20 to 80% by weight of polyarylene sulphides, from 10 to 60% by weight of glass fibers and from 60 to 10% by weight of mica.
摘要:
Highly crystalline, rapidly crystallizing thermoplastic compositions containing:a) 70-99.5% by weight of a polyphenyl sulphide having a melt viscosity of at least 5 Pas (measured at 306.degree. C. and at a shear stress of 10.sup.2 Pa) andb) 0.5-30% by weight, relative to a) and b) of an oligomeric ester having at least two repeating ester monomeric units and a maximum molecular weight, expressed as a number average, of 6000.
摘要:
A composite plastic structure is described. The composite structure includes: (a) a shaped polycarbonate article having an edge region, the edge region having an adhesion-promoting geometric feature therein; (b) a coating applied to the surface of the shaped polycarbonate article; and (c) a polymer that is injection-molded or cast over the edge region of the shaped polycarbonate article. The polymer (c) envelopes the adhesion-promoting geometric feature of the shaped polycarbonate article (a). The envelopment of the adhesion-promoting geometric feature by the polymer (c) provides a structurally firm connection between the shaped polycarbonate article (a) and the polymer (c). Also described is a method of preparing the composite structure, and composite structures according to the present invention, such as picture frames, slide frames, windows having a seal or frame, and a glazing for a motor vehicle.
摘要:
A UV-stabilizer comprising a mixture of hydroxybenzotriazole and a hydrolyzable silane containing at least one epoxy group is disclosed. The stabilizer is especially suitable as a component of a siloxane system for coating substrates, especially thermoplastic substrates and most especially polycarbonate substrates.
摘要:
The invention relates to coated moldings of polycarbonates with a coating (A) against the effect of UV radiation and, optionally a coating (B) to prevent the formation of droplets.
