Abstract

A method for using a novel dense PTFE article in the form of a surface for a food preparation device is described in one embodiment, the surface being fabricated from a sheet of PTFE with a thermal resistance of 1.3° C. in 2 /W or less and having desirable tensile strength.

Claims (12)

1. A method for improving the non-enzymatic browning on the surface of food comprising

placing said food on the surface of a PTFE sheet, said PTFE sheet having a density of 2.0 g/cc or more, a tensile strength of at least 8000 psi in two orthogonal directions, a surface thickness of up to about 2 mil and a thermal resistance of 1.3° C. in 2 /W or less, and said PTFE sheet being in contact with a heat source on the surface of the PTFE sheet opposite the surface in contact with the food; and

non-enzymatically browning the surface of the food.

2. A method for cooking food comprising

placing said food on the surface of a PTFE sheet, said PTFE sheet having a density of 2.0 g/cc or more, a tensile strength of at least 8000 psi in two orthogonal directions, a surface thickness of up to about 2 mil and a thermal resistance of 1.3° C. in 2 /W or less, and said PTFE sheet being in contact with a heat source on the surface of the PTFE sheet opposite the surface in contact with the food.

3. A method for cooking food comprising

placing said food on the surface of a PTFE sheet, said PTFE sheet having a surface comprising a polytetrafluoroethylene (PTFE) sheet having a thermal resistance of 1.3° C. in 2 /W or less, a surface thickness of up to about 2 mil and a tensile strength of at least 10,000 psi in at least one direction.

4. The method of claim 2 , wherein said sheet has a density of 2.1 g/cc.

5. The method of claim 2 , wherein said sheet has a thermal resistance of 1.0° C. in 2 /w or less.

6. The method of claim 2 , wherein said sheet has a thermal resistance of 0.5° C. in 2 /w or less.

7. The method of claim 3 , wherein said sheet has a thermal resistance of 1.0° C. in 2 /w or less.

8. The method of claim 3 , wherein said sheet has a thermal resistance of 0.5° C. in 2 /w or less.
