![]() ![]() OMEGA-PEEK ® exhibits excellent chemical resistance, very good dielectric properties and a very good resistance to all kinds of radiation (even ultraviolet rays only lead to a slight discolouration) and has very little effect of is self-extinguishing properties according to UL94. OMEGA-PEEK ® can be used at very high temperatures (about +260☌) and it shows an extraordinary mechanical strength, toughness, hardness, flexural strength and torsional strength. It is commonly used for high-friction mechanical parts such as screws and bearings.įor expertly CNC machined parts from precision engineering plastics, call Reading Plastic today at 61.OMEGA-PEEK ® Polyetheretherketone (PEEK) is semi-crystalline advanced material exhibits a unique combination of high mechanical properties, temperature resistance and excellent chemical resistance making it the most popular of the advanced plastic materials. PTFE is also hydrophobic, has high flexural strength, a large operating temperature range (between -328✯ and +500✯), and high electrical resistance and dielectric strength. Pure PTFE is almost totally chemically inert and highly insoluble in most solvents or chemicals, making it the perfect material to store or handle corrosive chemicals. More commonly known as Teflon®, PTFE is famous for having one of the lowest coefficients of friction against known solids. It is widely used for bearings and bushings, aerospace components, seals, pump and valve parts, and semiconductor machinery parts. With extremely low thermal expansion and superior creep resistance, PAI is an excellent choice for tight-tolerance applications. It has the highest tensile strength of any unreinforced thermoplastic (21,000 psi), as well as good wear and radiation resistance, and inherently low flammability and smoke emission. PAI (polyamide-imide) is an extremely strong, stiff, dimensionally stable plastic that maintains its mechanical properties at continuous temperatures up to 500✯. It is also available in a variety of grades that offer targeted enhanced properties. While PEEK’s high temperature resistance can make it difficult to process, in its solid state PEEK is readily machinable by CNC milling machines. It also has high tensile and flexural strength (16,000 psi and 25,000 psi respectively), very low moisture absorption, excellent electrical properties, and is biocompatible. ![]() PEEK offers high temperature resistance (with a melting point of over 700✯), high wear and abrasion resistance, outstanding resistance to harsh chemicals and superior creep resistance. PEEK is a high-performance engineering plastic with a unique combination of properties that makes it incredibly strong and dimensionally stable both under load and in the harshest environments. From bearings to critical aircraft parts, Vespel® can withstand the harshest operating conditions on the planet. Vespel® can easily be machined to achieve complex geometries and tight tolerances, allowing for the creation of designs that would be impossible with lesser materials. It is also lightweight, highly resistant to chemical corrosion (including industrial hydraulic fluids, fuels, and solvents), and doesn’t outgas, making it safe for vacuum applications. ![]() This highly durable polyimide has outstanding creep resistance and doesn’t lose its mechanical properties in extremely high temperatures (up to 500✯). When an application demands excellent strength and impact resistance, low wear and/or low friction rates, and high thermal resistance, engineers turn to Vespel®. PEI can be found in semiconductor equipment components, medical and chemical instrumentation, aerospace parts, automotive applications, and more. ![]() Combined with its mechanical properties, PEI’s processability offers great flexibility and freedom to design engineers. It is also inherently flame resistant, has excellent chemical and hydrolysis resistance, and one of the highest dielectric strengths of any thermoplastic material.Īlso known as Ultem®, PEI has outstanding dimensional stability and is easily machined and fabricated. Its long-term creep resistance also makes it a great replacement for metal and other materials in many structural applications. With a tensile strength of 15,200 psi and continuous use up to 340✯, PEI (polyetherimide) plastic is a lower cost alternative to PEEK. Below are five of the best precision engineering plastics on the market, able to tackle the most challenging applications in any industry. Today’s precision engineering plastics offer superior chemical resistance, higher temperature capability, greater dimensional stability, good wear resistance, and excellent machinability. ![]()
