Engineering polymers are a group of plastic materials that have improved mechanical and thermal properties that make them ideal for all types of engineering applications, replacing traditional materials equal or greater in weight, hardness or other properties, while being much simpler to manufacture, especially with complex shapes.
This semicrystalline thermoplastic is one of the most widely used engineering thermoplastics by providing well balanced properties in strength, stiffness and chemical resistance. It has improved surface appearance and processability compared to PA 66 but lower modulus and absorbs moisturemore rapidly. PA 6 can be processed by extrusion (e.g. fibres, profiles) and injection.
PA 6.6 offers an excellent balance of mechanical properties (strength, stiffness, impact) and heat / chemical resistance. Therefore PA 6.6 very often is considered as an outstanding candidate for metal replacement.
Polyamides (PA) can be modified with fillers, fibers, internal lubricants, impact modifiers etc. to improve mechanical properties, heat and chemical resistance or processability depending on the demand of end-use and application requirement.
Polycarbonate is a transparent thermoplastic with excellent impact resistance. Its high performance properties make it the leading plastic for various applications requiring high operating temperatures and safety features. Polycarbonates are unique in their working temperatures and in their ability to experience minimal degradation between heating and cooling points.
POM C, also known as polyacetal copolymer or acetal resin, is a highly crystalline, and therefore strong and rigid, engineering plastic with a low coefficient of friction compared to metals and other plastics. It is also creep resistant and is recommended for applications where dimensional stability is important.
POM H has a higher mechanical strength, rigidity, hardness and creep resistance than POM C, and a lower coefficient of thermal expansion.
A polymer mixture ("alloy") is the combination of two or more polymers that fuse to create a new material with different physical properties. Polymer blends are an effective method of developing new polymer-based materials for a wide range of applications. The key to their proper use is to adjust the properties of the new material by appropriate selection of the component polymers.
PPS is a semicrystalline polymer offering excellent properties in high temperature and chemical resistance as well as dimension stability. Because of its inherent flame retardancy PPS is often used for electrical applications requiring high temperature resistance. Due to its low viscosity PPS can be moulded even with high loading of fillers and reinforcements.
