Prime PP COPP 792

This product is a fractional melt PP that is designed for extrusion applications with features of high extrudate melt strength, good cold impact resistance, stiffness and and impact balance. It also offers better optical properties, increased flexibility, and the same chemical resistance as Homopolymer PP.

Applications:
Prime COPP 792 is ideal for home, medical and food ware.

Processing:
Prime COPP 792 can be solid phase or melt phase formed. The melt phase forming process is preferred, with a forming temperature of 350°F. The mold temperature should be 50-90°F for roll fed machines and 90-150°F for cut sheet machines. The mold shrink is about .015 - .018 in/in. Parts should be de-molded <190°F.

Finishing:
Thinner sheet <.040 is easily trimmed with 1- 2 minutes of cooling time. Thinner sheet can be trimmed with a steel rule die. Thicker sheet will require several minutes of cooling time and should be trimmed with a shearing die. Tool and die clearance should be <.005 in. For printing or painting corona or flame surface treating is required.

Please contact your Primex Plastics representative for more information on finishing, fabricating, or the thermoforming process.
