![]() ![]() The annealing process at AIP greatly reduces the chances of these stresses occurring from the heat generated during machining PP and other polymers. This feature makes it a suitable option for lightweight\weight saving applications.ĭue to its low annealing temperature, PP, like any polymer under heat and pressure, has a tendency to deform during machining. Melting Point of Polypropylene – The melting point of polypropylene occurs at a range.ĭensity of Polypropylene – PP is one of the lightest polymers among all commodity plastics. Whatever your application, our machinists can help you in material selection, sizing and manufacturing techniques from concept to completion. Interesting to note is that both the PROPYLUX and TECAPRO heat stabilized PP grades are available in both standard and custom colors for medical sorting and sizing organization. At AIP, we machine POLYSTONE P, PROPYLUX HS and HS2, PROTEUS LSG HS PP from MCAM, TECAPRO MT and TECAFINE PP from Ensinger. As noted above, it is available in heat-stabilized homopolymer and copolymer grades. It also has great dimensional stability and is fairly easy to machine. Polypropylene is characterized by excellent chemical resistance in corrosive environments, resistance to cleaning agents and solvents and by a high heat deflection temperature. Here are some of the key properties of polypropylene: It also assists in evaluating if the end use requirement would be fulfilled or not. This helps in selecting the right thermoplastic for an application. Keeping information about the properties of a thermoplastic beforehand is always beneficial. Not preferable for food contact applications. ![]()
