Material Notes:
ApplicationsALATHON L 4903 is a high molecular weight high density copolymer with broad dimodal molecular weight distribution. This resin exhibits excellent machine direction tear in an HMW-HD resin as well as low gel levels. Typical applications include trash liners and products requiring incorporating PCR.Regulatory StatusL 4903 meets the requirements of Food and Drug Administration regulation, 21 CFR 177.1520. This regulation allows the use of this olefin polymer in "…articles or components of articles intended for use in contact with food." Specific limitations or conditions of use may apply. Contact your Equistar sales representative for more information. Processing TechniquesSpecific recommendations for processing L 4903 can only be made when the processing conditions, equipment and end use are known. For further suggestions, please contact your Equistar sales representative.Typical Extrusion Conditions: BUR=4.1, Neck Height=8 Die Diameters, 0.5 Mil Film, Melt Temperature- 390-410°F(199-210°C)This product is from the former Equistar product line.
