AGC Chemicals Americas Inc. (Exton, Pa., U.S.) is introducing mPLASTICS, new fluoropolymer-modified compounds to enhance the performance of carbon-fiber reinforced thermoplastic (CFRP and CFRTP) composites with strength, impact resistance, wear resistance, flexibility, heat tolerance, adhesion and electrical properties.
According to the company, mPLASTICS compounds are ideal for applications that require a durable, lightweight material, such as automobiles, aircraft and sporting goods. Parts and components molded at high temperatures with these materials are said to have fewer defects, improving yields.
At the virtual CAMX conference, David J. Lavanga, innovation engineering manager with AGC, is presenting “Improving Engineering Plastics Performance by Fluoropolymer Modification.” He is discussing performance advantages of using fluoropolymer-modified polyamides (mPA), fluoropolymer-modified polyetheretherketone (mPEEK) and fluoropolymer-modified polyphenylene sulfide (mPPS) in composite applications.
According to AGC Chemicals, mPEEK can be used to produce different geometries such as sheets, rods, tubes, gears, liners, wire and cable insulations, and films that better withstand demanding operational conditions. The modified material is also said to improve processability via extrusion molding, injection molding and compression molding, and to demonstrate a lower dielectric constant than standard PEEK at high temperatures up to 260°C.
The company says that mPPS can be used to produce films, bearings, bushings, hoses and other flexible tubing and liners for chemical processing and oil & gas industries. It is said to be ideal for applications that require high temperatures (greater than 200 °C) and chemical resistance as well as retained performance.
Lightweight, hard and stable at high temperatures, CMCs are emerging from two decades of study and development into commercial applications.
There are numerous methods for fabricating composite components. Selection of a method for a particular part, therefore, will depend on the materials, the part design and end-use or application. Here's a guide to selection.
For composite applications, these hollow microstructures displace a lot of volume at low weight and add an abundance of processing and product enhancements.
