Engineering Plastics


Polycarbonates (PC) are a particular group of thermoplastic polymers that are easily worked, moulded, and thermoformed; as such, these plastics are very widely used in the modern chemical industry. Their interesting features (temperature resistance, impact resistance and optical properties) position them between commodity plastics and engineering plastics.


PMMA, is a transparent thermoplastic, often used as a light or shatter-resistant alternative to glass. Chemically, it is the synthetic polymer of methyl methacrylate. PMMA is an economical alternative to polycarbonate (PC) when extreme strength is not necessary. It is often preferred because of its moderate properties, easy handling and processing, and low cost, but behaves in a brittle manner when loaded, especially under an impact force, and is more prone to scratching compared to glass.


Polyamide is a polymer containing monomers of amides joined by peptide bonds. They can occur both naturally and artificially, examples being proteins, such as wool and silk, and can be made artificially through step-growth polymerization, examples being nylons, aramids, and sodium poly (aspartate). Polyamides are commonly used in textiles, automotives, carpet and sportswear due to their extreme durability and strength.


Polyoxymethylene (POM) is often marketed and used as a metal substitute. It is a lightweight, low-friction, and wear-resistant thermoplastic with good physical and processing properties and capable of operating in temperatures in excess of 90 degrees Celsius. Polyoxymethylene commonly referred to as POM and also known as polyacetal it is used in precision parts that require high stiffness, low friction and excellent dimensional stability.


Polybutylene terephthalate (PBT) is a crystalline resin that offers some of the best heat resistance, chemical resistance and electrical properties of all engineering plastics. Crystallization is rapid, so cycle times are short, while weather resistance, friction resistance, wear resistance, dimensional stability and heat aging resistance are all outstanding. PBT is known for its great physical property balance and economical benefits.


Thermoplastic Elastomers (TPE) - TPEs are a family of polymers that can be repeatedly stretched without permanently deforming the shape of the part. Unlike rubber-like elastomers, they do not require curing or vulcanization, as they are true thermoplastics. Thermoplastic elastomers (TPEs) may be processed by conventional thermoplastic techniques such as injection molding, extrusion and blow molding.
