Abstract
An un-reinforced thermoplastic molding composition suitable for the production of fibers, films and molded articles is disclosed. The inventive composition contains polyester, melamine cyanurate, a phosphorus-containing flameproofing agent, an ester or amide of saturated or unsaturated aliphatic carboxylic acids with 10 to 40 C atoms with aliphatic saturated alcohols or amines with 2 to 40 C atoms, and processing auxiliary substances.
Claims11
A thermoplastic molding composition consisting of
- A) 55 to 93.99 wt. % of a or a mixture of polyester,
- B) 3 to 15 wt. % of melamine cyanurate,
- C) 3 to 15 wt. % of at least one phosphorus-containing flameproofing agent in which the valence of the phosphorus is −3 to +5,
- D) 0.01 to 5 wt. % of at least one ester or amide of saturated or unsaturated aliphatic carboxylic acids with 10 to 40 C atoms with aliphatic saturated alcohols or amines with 2 to 40 C atoms,
- E) 0 to 10 wt. % of at least one member selected from the group consisting of stabilizers, antioxidants, thermal stabilizers, UV stabilizers, lubricants, mold release agents, rubber-elastic polymers, colorants, , nucleating agents and plasticizers,
- in which the total sum of the percentages by weight of the components A) to E) is 100%, the composition excluding reinforcing agents and fillers selected from the group consisting of mineral, carbon and glass fiber-shaped particulates and spherical particulates and amorphous silicic acid.
