Polypropylene (PP) Is A Semi-Crystalline Thermoplastic That Comes In Two Different Forms; It Can Be Composed Of Homopolymers Or Copolymers. Homopolymer Polypropylene Is The Most Generic Grade Whereas Copolymer Polypropylene Has Varying Degrees Of Ethylene Mixed Into It. Machining Polypropylene May Be More Challenging Than With Other Common Plastics Due To Its Tendency To Gall And Melt. Polypropylene's Excellent Chemical Resistance And Fatigue Strength Make It Especially Useful For Flexible Parts And Parts That Are Exposed To Corrosive Environments.

While CNC Machining In Polypropylene Is Challenging Due To Its Tendency To Gall And Melt, Homopolymer Polypropylene Offers A Range Of Benefits For CNC Machined Parts. Its Slick Surface Makes It Ideal For Mechanical Items Like Gears And Its Fatigue Resistance Means That Thin Features Such As Living Hinges Are Easy To Incorporate Into Designs.
