5. The mold of claim 4, wherein the cyclic olefin copolymer has an HDT of from about 165 ℃ to about 200 ℃.

6. The mold of claims 1-5, wherein the molding surface has a surface energy from about 15 dynes/cm to about 35 dynes/cm at 20 ℃ characterized by a surface measurement test according to ISO8296 test standard.

7. The mold defined in any one of claims 1-6, wherein the mold wall forms at least a portion of a first mold portion, and the mold further comprises a second mold portion, wherein the first mold portion and the second mold portion are configured to move relative to one another between an open position and a closed position, and wherein the first mold portion and the second mold portion in the closed position define a cavity for molding the article-forming material.

8. The mold defined in any one of claims 1-7, wherein the mold is a mold for forming a molded footwear component, a molded apparel component, or a molded athletic equipment component.

9. A method for forming a molded article, the method comprising:

Introducing an article-forming material into a mold, the mold comprising a mold wall comprising a cyclic olefin copolymer; and

Contacting the article-forming material with a molding surface of the mold wall for forming the molded article.

10. The method of claim 9, wherein the cyclic olefin copolymer comprises a copolymer of polyethylene and norbornene.

11. The method of any one of claims 9 or 10, wherein the mold wall is substantially transparent to Ultraviolet (UV) light, and wherein the method further comprises transmitting the UV light through the mold wall to the molding surface for exposing the article forming material to the UV light.

12. The method of any one of claims 9 or 10, wherein the article forming material is a UV radiation curable material, and wherein the method further comprises curing the article forming material in response to exposure to the UV light.

13. The method of claim 12, wherein the UV radiation curable material is a UV radiation curable elastomer or rubber material, and wherein curing comprises curing the UV radiation curable elastomer or rubber material in response to exposure to the UV light.

14. The method of claim 13, wherein the UV radiation curable elastomer or rubber material is a UV radiation curable urethane rubber, and wherein curing comprises curing the UV radiation curable urethane rubber in response to exposure to the UV light.

15. The method of any of claims 9-14, wherein the mold wall forms at least a portion of a first mold portion, and the mold further comprises a second mold portion, and wherein contacting comprises moving the first mold portion and the second mold portion relative to each other to a closed position for molding the article-forming material.

16. The method of any one of claims 9-15, wherein the molded article is a molded footwear component, a molded apparel component, or a molded athletic equipment component.

17. The method of claim 16, wherein the molded article is a molded footwear component.
