USDA Same as above Polystone® M (UHMW-PE) has USDA approval for meat and poultry in food handling applications. Federal L-P-390C Plastic, molding and extrusion material, polyethylene and copolymers (low, medium and high density) Military MIL-P-23536 MIL-P-21922 Plastic sheets, virgin and borated polyethylene Plastic rods and tubes polyethylene OSHA Polystone® M (UHMW-PE) is not considered hazardous, as defined by the OSHA Hazard Communications Standard 29 CFR 1910.1200 * Industry standard testing method using a slurry of 60 % aluminum oxide and 40 % water at a rotation speed of 1750 rpm for 2 hours. Results indicate the ability of each material, in relation to Natural (=100), to resist abrasion under typical UHMW-PE applications. A lower number indicates better abrasion resistance. The information listed herein is stated to the best of our knowledge and is intended to provide a general guideline for Polystone® M and its uses. The values given are based on laboratory testing backed with global industry experience. All properties in this brochure have performed equal or better in laboratory testing. However, the data should not be considered as guaranteed specific properties. Suggested applications are provided for information only and are not specific recommendations. 9PDF Image | Polystone G(HDPE)
