Biaxially oriented polypropylene (BOPP) processes
64 Biaxially oriented polypropylene (BOPP) processes up ratio (TUR). Increasing BUR rotates the b axis into a direction normal to the film surface. A similar effect can be found in tubular film operations at fixed BUR, where the TUR is decreased. When TUR equals BUR, the biaxial orientation factors are similar. The same observation

Injection Molding Guide
Melt flow rate (MFR) is a simple measure of a polymer's melt viscosity under standard conditions of temperature and static load (pressure). For polyethylenes, it is often referred to as melt index (MI). MFR is the weight in grams of a melted resin that flows through a standard-sized orifice in 10.

Flame retardant treatments for polypropylene: Strategies …
Polypropylene (PP), one of five general-purpose plastics, is widely used in many fields. However, the intrinsic alkane structure of PP makes it relatively easy to burn, leading to limiting its scope of application. Here, this article reviews the most commonly flame retarding strategies used in PP matrices, including the flame-retardant ...
