A group of plastic materials that have better mechanical and/or thermal properties than the more widely used commodity plastics (such aspolystyrene, PVC, polypropylene and polyethylene).
NYLON-6 &66:-
It is one of the most valuable engineering plastics, particularly for applications requiring high mechanical properties along with chemical and heat resistance and excellent finish. Polyamide is often the answer for designers seeking weight savings, functional integration, design freedom and cost reduction.
PBT is a semi-crystalline engineering thermoplastic with excellent insulation properties and it is majorly used in electrical and electronics industry. Un-reinforced grades offer performance typical to a crystalline polymer, combining good strength and stiffness with low moisture absorption, high thermal stability, exceptional electrical insulation, outstanding dimensional stability and resistance to the effects of a wide range of chemicals, solvents, and oils.
It is primarily used in automotive and electrical applications. It is also being used in a variety of other segments where the application requires high impact strength and heat resistance along with a smooth surface finish.
PET is a semi-crystalline engineering thermoplastic. Besides the property of good heat resistance, this lightweight product also has excellent gas barrier properties and fair resistance to moisture. It can be classified as rigid or semi-rigid depending upon how it is processed. The product often finds application in automotive, electrical & electronics, furniture and medical industry.
