Polyesters are manufacturing thermoplastics derived from polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) (PET). They have outstanding mechanical, electrical, and thermal properties, as well as excellent chemical resistance and dimensional stability.
What are the key features of Polyesters?
Polyesters have a high degree of stiffness and impact resistance. They have high heat resistance as well as excellent dimensional stability (due to low water absorption compared to Nylons, for example). Chemical and weather resistance are excellent in these materials.
Additionally, since the material’s natural colour is translucent, it comes in a wide variety of colours.
Types of Polyester finish
Standard metal machining machines may be used to process the material on traditional lathes. Adhesives may be used to adhere it. All known printing systems can be used to decorate it, but inks have a hard time adhering to the material due to its chemical resistance, so a primer should be used. Painting parts is easy. The best plating process is vacuum metallization. Vibration, spin, hot-plate, and ultrasonically welded parts are all options.
What is Polyester used for?
PET is most commonly used in the production of blow-molded bottles. PBT is used in high-quality, high-stress engineering components such as windscreen wiper arms, door handles, and particularly electronic parts in automobiles; household appliances; and electric and electronic engineering, such as circuit breakers.
