Prime PE HDPE 250

About
Is a fractional melt with a density of .950 – .955 and a melt index of .2 -.35. Our Prime HDPE 250 offers characteristics such as good stiffness and stress crack resistance. Along with being light weight and tough, it is an ideal selection for many interior or exterior parts. Applications: Prime HDPE 250 is ideal for forming trays, food packaging, small dunnage, or any other parts that requires cold temperature impact. It also works well for small lawn tractor parts, and many other small tool components. Processing: This is a crystalline material, therefore it requires more attention than an amorphous material. It is recommend that it be formed on an aluminum tool that is temperature controlled, grit blasted and with a moat on the outside of the trim line. The forming temperature should be 300-350°F. The tool temp. should be 160-190°F. Finishing: Prime HDPE 250 may be drilled, routed, punched, sawed, die cut, laser cut, or cut using water jet. Mechanical fasteners and screws may be used. Contact the 3M company for information on bonding. Caution, the CLTE is higher than other thermoplastic materials. Please contact your Primex Plastics representative for more information on finishing, fabricating, or the thermoforming process. Colors, Textures and Capabilities: Prime HDPE 250 can be color matched to meet your specific requirements. Prime HDPE 250 is offered in thicknesses of .015 – .425 and widths of up to 169″. Textures include; RM, H/C, Levant l, II, & lll and Seville.&&
