Polypropylene 290 Specifications

Description

Polypropylene 290 is the next generation of heat-stabilized polypropylene. Polypropylene 290 is produced from a FDA approved homopolymer resin, and exhibits better heat and dimensional stability over Polypropylene.

Applications

Tanks/tank covers • Food strainers • Hot fillers • Welding cabinetry • Etching rinse tubs • Glove boxes • Cutting board • Fan shroud and blades

Advantages of Polypropylene 290

Excellent chemical resistance • Lot controlled and traceable • Low moisture absorption • FDA resin • Superior dimensional stability

Manufacturing Capabilities

Sheet: 3/4” to 21/2” thick • Sheet Sizes: 24”x48” 48”x96” 48”x120” • Rod: 3/8” to 4” diameter

Color/Grades

Standard: Natural (custom colors available).
