Abstract
A polymer composition is disclosed, which comprises a matrix polymer, a fluoropolymer that may be at least partially encapsulated by an encapsulating polymer, and a filler. Methods for making the polymer compositions and articles made of such compositions are also disclosed. The compositions and article can have improved tensile modulus, ductility, and/or impact properties.
Claims29
A polymer composition comprising a combination of:
- a matrix polymer component;
- a fluoropolymer;
- and
- a filler, wherein the polymer composition has a tensile modulus of greater than or equal to about 3 Gpa, and a nominal elongation at break of greater than or equal to about 20%, measured in accordance with ISO-527, using a rate of pull of 1 mm/minute followed by 5 mm/minute.
A polymer composition comprising:
- a matrix polymer component;
- a fibrillatable fluoropolymer;
- and
- a filler, wherein the fluoropolymer is fibrillated by in situ mixing with the matrix polymer and filler.
A mixed polymer composition comprising:
- a matrix polymer component;
- a filler;
- and
- a fluoropolymer, wherein the fluoropolymer is fibrillated during mixing with the matrix polymer and/or filler to a degree effective to provide the composition with a higher tensile modulus than the same composition without fibrillation of the fluoropolymer.
A method of preparing a polymer composition, comprising
- mixing a matrix polymer, a fluoropolymer, and a filler under conditions of shear and temperature effective to form a composition having a tensile modulus of greater than or equal to about 3 Gpa, measured in accordance with ISO-527 using a rate of pull of 1 mm/minute followed by 5 mm/minute.
A method of preparing a polymer composition, comprising
- mixing a matrix polymer, a fibrillatable fluoropolymer, and a filler under conditions of shear and temperature effective to fibrillate the fluoropolymer.
