"PROPOSED UV RATING METHOD FOR UV STABILIZED INJECTION MOLDING POLYETHYLENE"
BY JON RATZLAFF, CHEVRON PHILLIPS CHEMICAL CO. LP

The European injection molding market is filled with numerous injection molding resins that claim resistance to ultraviolet light from outdoor exposure. However, few, if any, have actual comparable data that allows a buyer to distinguish the performance of one resin to another. Likewise, if artificial weathering results are given, how does this relate to actual outdoor performance? Can a relation to outdoor performance be translated to geographic variances in weather? This paper gives a summary of several published artificial ultraviolet exposure studies, some known standards with industry acceptance and how the tests relate to outdoor exposure with a concise experiment between two UV test methods. Finally, a proposal is given of standardized ultraviolet resistant testing for the injection molding world of polyethylene. This includes estimating outdoor performance with the variances of solar radiation based on geography.

Jon Ratzlaff has been involved in the plastics industry for over 25 years. He holds experience in numerous disciplines such as rotational molding, injection molding, compounding, extrusion, film, sheet and thermoforming. His alma mater is Oklahoma State University (Go Cowboys!) with a B.S. in Chemical Engineering. He has time well spent in management, manufacturing, quality, research and development, and technical service which includes his favorite: product/application & business development. He is currently focused on application development and technical services for rotational molding and injection molding polyethylene line of products for Chevron Phillips Chemical Company.
