Abstract:
A polyolefin composition comprising: (A) from 97.0 to 45.0 wt% of a propylene-1-hexene random copolymer, (B) from 2.0 to 50.0 wt% of fibers, and (Q) from 0.3 wt% to 5.0 wt% of a compatibilizer, the sum (A) + (B) + (Q) being 100, wherein (i) the copolymer has a content of 1-hexene derived units ranging from 0.6 wt% to 3.0 wt% with respect to the copolymer, (ii) the copolymer has the melt flow rate (MFR) measured according to the method ISO 1133 (230° C, 2.16 kg) ranging from 0.2 up to 40 g/10min, (iii) the fibers are selected from the group consisting of glass fibers, carbon fibers, metal fibers, mineral fibers and ceramic fibers.
Abstract:
Polymer composition suitable for ABS styrenic resin replacement where high dimensional stability and a good esthetical appearance is required, comprising a polymer blend (A), comprising 60-80% by weight, of a crystalline propylene homo or copolymer (A1) (MFR
Abstract:
The invention relates to a glass fiber-reinforced molding composition composed of an olefin polymer, in particular a propylene polymer. The molding composition comprises an olefin polymer which contains 5-50% by weight of glass fibers which are bonded to the olefin polymer by means of a compatibilizer, and from 10-4 to 1% by weight, preferably from 10-3 to 10-1% by weight, of a phthalocyanine pigment as the nucleating agent. The low costs and the fact that even a very small fraction of the phthalocyanine pigment in the polymer leads to sufficient nucleation ensures extremely inexpensive production. The nucleation with the phthalocyanine pigment leads to an improvement in the impact strength, and also in the yield stress and tensile strain at break of the molding composition.
