  • Patent number: 9512292
    Abstract: The present invention relates to a fuel part, comprising a polymer composition comprising: i. a polyamide A, and ii. micro talcum in an amount of 0.001 to 1 weight percent with respect to the total amount of the polymer composition, wherein the polymer composition has a melt volume flow rate (MVR) of at most 70 cm3/10 min at a weight of 21.6 kg and at a temperature of Tmeasure as measured according to ISO 1133. The invention also relates to a process for preparation of such fuel part wherein a blow-molding or roto-molding process is applied.

  • Patent number: 9399314
    Abstract: The present invention relates to a process for preparing an injection molded part, comprising the following steps: a preparing a glass fiber reinforced polyamide-6 composition with a relative viscosity of less than 2.4; b heating a such composition to obtain a viscous liquid; c filling a mold cavity with the viscous liquid with a filling time of at least 0.8 s; d leaving the viscous liquid in the mold under pressure until it cools to form a part; e opening the mold; f ejecting the part; wherein the polyamide-6 composition has a crystallization temperature under hyper DSC conditions of less than 168° C. The invention also relates to an injection molded part a having a maximum wall thickness of at least 2.5 mm; and/or b a part weight of at least 100 g per injection point; wherein the part consists of a glass fiber reinforced semi-crystalline polyamide-6 composition having a relative solution viscosity of less than 2.
