eFunda Polymers: Listing of Polypropylene (Marlex HGL, Fortilene 1800 series (FDA materials))

Introduction

Polypropylene, also known as PP, has been mass-produced since 1950's .
-	It is a thermoplastic, (crystalline), polymer.
-	Applications: PP can be used to make medical syringes, beakers, and parts for auto interiors.
-	General properties: Its key attributes are high lubricity, high resistance to flexing (excellent material for living hinges), excellent dielectric strength and chemical resistance, good impact strength, and high solvent resistance. It is inexpensive and electroplatable, but it is difficult to paint, print on, or bond to. It will be attacked by fuming nitric acid and degraded by UV and ionizing radiation.
-	Trade Name: Marlex HGL, Fortilene 1800 series (FDA materials).
