## Abstract

A golf tee may be constructed with a body formed from a polymer tolerant of exposure to a temperature at least as high as 480° F. without incurring diminishment of its structural integrity. A low-friction coating may be applied to a ball support of the tee.

## Claims

### Claim 1

A golf tee, comprising:
a tee body having a lower end and an upper end, wherein said upper end is comprised of a ball support;
wherein said ball support is comprised of at least six cusps positioned on an outer periphery of said ball support and extending upwardly, wherein said at least six cusps have a median width of about 0.025 inch to about 0.050 inch and a height of about 0.04 inch;
wherein said tee body is comprised of a polymer-fiber composition having a polymer mixed with glass fibers, wherein said polymer-fiber composition is tolerant of exposure to a temperature of at least 480° F. without melting or incurring diminishment of its structural integrity; and
a fluorine/polymer coating applied to said ball support, said fluorine/polymer coating further comprised of polytetrafluoroethylene, wherein said coating is fused to said ball support at a temperature of at least 480° F. and wherein said coating has a thickness of between 0.005 inch to 0.010 inch.

### Claim 2 (depends on 1)

The golf tee of claim 1, wherein said coating is applied to at least an upper surface of said ball support.

### Claim 3 (depends on 2)

The golf tee of claim 2, wherein said coating is applied to a side portion of said ball support.

### Claim 4 (depends on 1)

The golf tee of claim 1, wherein said polymer is comprised of nylon.
