o Polytetrafluoroethylene: plumber's tape, frying pans, heat-resistant etc
o Polyetheretherketone: commercial polymers, aerospace mouldings etc.
o Polyetherimide: Polymer that does not crystallize etc.

Numerous researches have been made to develop variety of application of plastic in which UPVC is one of them. Today upvc is used manufacturing doors and windows. UPVC stands for 'Unplasticized Polyvinyl Chloride'.

UPVC is one of the plastics that has many benefits if used in manufacturing of windows and doors. As it is available in different colors, we can have windows or doors of our interest. UPVC doors and UPVC windows can be given different designs of texture finish.

Moreover, UPVC doors and UPVC windows have the nature that it doesn't corroded by the time. Weather doesn't do anything to its products. It has anti corrosion nature that makes it very durable.
