Introduction To Plastics
Engineering plastics, also called thermoplastic polymers, are a group of plastic materials that have better mechanical and/or thermal properties than commonly used commodity plastics. Some advantages of engineering plastics include: good mechanical characteristics; heat stability up to temperatures between 120° to 150°; excellent machinability and dimensional stability; being lightweight, having higher strength, and minimal friction; and good chemical resistance, resilience, stiffness, durability, and electrical properties.
These properties make engineering plastics suitable for mechanical parts in industries such as manufacturing and machinery, automotive and transport, electrical and electronics, engineering, construction, food, and consumer products. Engineering plastics can be extruded or cast as rod, tube, or sheet profiles. Common grades of engineering plastics include, Acetals, Polyethylenes, Nylons, PEEK, PTFE, and PETP. Kormax’s knowledgeable staff can help you choose the right polymer for your product’s specific application.
Acetal
Acetal is a high-performance engineering polymer, also known as polyacetal, polyoxymethylene (POM) or polyformaldehyde. It is a high strength, low friction, semi-crystalline engineering plastic with low moisture absorption, and its FDA compliance allows for direct contact with food stuffs. Kormax Acetal generally comes in either natural white or black colour.
Polyethylene
Polyethylene (PE) is one of the most popular thermoplastic materials, which is available in different crystalline structures. Kormax offers the linear versions of PE grades, known as HDPE (High Density Polyethylene) and UHMWPE (ultra-high-molecular-weight polyethylene).
In general, Polyethylenes (considered a dielectric material) offer excellent chemical and impact resistance, electrical properties, and low coefficient of friction. Polyethylenes are also lightweight, easy to process and offer almost zero moisture absorption. These polymers are highly suitable for the food processing industry, high speed conveyers, chain guides, chute liners, and packing machinery parts, amongst others.
Nylon
Nylon PA is a synthetic semi-crystalline thermoplastic from the polyamides polymers family. Nylon plastic is one of the most used polymers as it is a strong and stiff engineering plastic with excellent bearing and wear properties. It is frequently used to replace metal bearings and bushings, which often eliminates the need for external lubrication.
Other benefits of Nylon include reducing the part weight, reducing operating noise and reducing wear on mating parts. It is also commonly used for wear parts, gears, wheels and rollers, seals and gaskets, packaging machinery parts, food processing machinery parts, etc. Nylon Castings are available in rods, tubes, and sheets.
Performance Plastics
High performance plastics are a family of polymers that meet higher performance standards than standard engineering plastics. They have superior mechanical properties, outstanding chemical resistance, and high thermal stability – typically having a permanent operating temperature of more than 150°C. Due to these properties, high performance plastics like PTFE, PEEK, and PETP are chosen for applications requiring good chemical resistance, performance at elevated temperatures, low coefficient of friction and high strength.
Further benefits include great dimensional stability, excellent creep resistance for tight tolerances, and high tensile strength. They are used in many demanding and specialised applications across a variety of industries such as oil and gas, aviation, chemical processing equipment, mechanical, and biomedical.
