Abstract
Provided is an injection-molded article made up of a thermoplastic polymer material comprising a polyethylene terephthalate (PET) matrix, and at least one pigment and at least one nucleating agent dispersed in said PET matrix. The thermoplastic polymer material comprises no more than 5 wt % of mineral filler relative to the total weight of the article, and the article has a variable thickness ranging from 0.2 mm to 10 mm, at least two adjacent areas having a difference in thickness of at least 10%. A method for producing such an article is also provided.
Claims14
An injection-moulded article that consists of a thermoplastic polymer material including:
- a polyethylene-terephthalate (PET) matrix, and
- at least one pigment and at least one nucleation agent, in which said pigment and said nucleation agent is dispersed in said PET matrix,
- said article being characterised in that said thermoplastic polymer material comprises no more than 5% by weight of inorganic fillers with respect to the total weight of the article, and
- in that said article has a non-constant thickness varying between 0.2 mm and 10 mm, with at least two adjacent areas having a difference in thickness of at least 10%,
- wherein said injection-moulded article is a cooking utensil.
