Thermoplastics are materials that become pliable when heated to a specific temperature and solidify upon cooling. Learn about their molecular structure, amorphous and semi-crystalline thermoplastics and more!
Thermoplastics and thermosets are important materials in Additive Manufacturing. Learn about the difference between monomers and polymers, their molecular structures and distinct characteristics.
Why is water a problem for a part made of thermoplastics? Textbooks describe that the water uptake for some types of polyamide (PA) is really high in both 50% relative humidity and in water. This alone would not be the problem, but the uptake of water leads to very different properties of materials. How can dynamic mechanical analysis (DMA) help with this issue?
PMMI (Polymethacrylmethylimide) is a thermoplastic polymer. As it is an amorphous polymer, it features high transparency. The case study describes how thermal analysis methods can be employed to discover everything about the material.
Bringing cost, material, production process and quality successfully together is one of the key objectives in the injection molding industry. If the production process is not correct or if the material does not adhere to the specified requirements, low quality and thus scrap production is the consequence. Ideally, all of these four factors should be able to be managed in order to avoid scrap production. Thermal analysis methods offer valued approaches.
Thermoplastic materials have enjoyed increasing popularity in automotive manufacturing. Current environmental and economic concerns additionally raise the awareness of the various advantages of the material. Learn which materials are the most popular in today’s cars.
Plastics have significantly gained importance in automotive engineering. From being a metallic colossus in the 1950s, cars have been transformed to modern, lightweight versions of their former selves. The material does not only act as a design component. More importantly, thermoplastics are a booster for fuel efficiency due to its low weight. This evolution brings about severe challenges for suppliers and OEMs. They have to tackle five challenges to remain part of the future automotive ecosystem.
Plastics continue to be an innovative, indispensable and future-oriented material. 225,000 visitors from 165 countries informed themselves about recycling systems, sustainable raw materials and resource-saving processes at K show 2019 in Düsseldorf. Sustainability, industry 4.0 and automation solutions are the leading topics of the exhibitors.
