Abstract
A plastic composition consisting essentially of plastic matter, inorganic matter, and organic matter. The plastic composition has a notched izod impact above 12 J/m, a surface energy of at least 40 dyne/cm and, and when the plastic composition is subjected to injection molding, at least one of a tensile strength of above about 2.7 MPa, a tensile modulus of above about 600 MPa, a flexural modulus above about 690 MPa, a flexural strength above about 5.6 MPa, and a Charpy Impact above about 1.5 KJ/m2.
Claims8
A plastic composition consisting essentially:
- 1 weight percent to 50 weight percent of inorganic matter based on a total weight of the plastic composition,
- 15 weight percent to 35 weight percent of plastic matter based on the total weight of the plastic composition, and
- a remainder of non-plastic organic matter;
- wherein the plastic composition is an extrudate;
- wherein the inorganic matter, the non-plastic organic matter and the plastic matter are homogeneously dispersed in a continuous medium of the plastic composition;
- wherein essentially all gaps between the non-plastic organic matter and the continuous medium, essentially all gaps between the plastic matter and the continuous medium, and essentially all gaps between the inorganic matter and the continuous medium are less than 0.1 micrometers in width;
- wherein the plastic composition:
- has a notched izod impact above 12 J/m and
- has a surface energy of at least 40 dyne/cm;
- and
- wherein a sample of the plastic composition that has been subjected to injection molding, has at least two of the following:
- tensile strength of above about 2.7 MPa,
- tensile modulus of above about 600 MPa,
- flexural modulus above about 690 MPa,
- flexural strength above about 5.6 MPa, and
- Charpy Impact above about 1.5 KJ/m2.
