Polyester

Introduction:

Polyester is a polymer with ester functional group as a main chain. This is also known by other name Terylene. It is available in many forms but commonly it is used as PET (polyethylene terephthalate).Other forms which are known are polycarbonate and plant cuticles or cutin. Polyesters are easily flammables on high temperatures. Due to its wrinkle resistance capacity it is widely spun together with other natural fibres. Liquid crystalline polymers have high heat resistance capacity so it is used in jet engines as an abradable seal. Its one wide spread application in the medical field is for making of heart valves. Some properties of Polyester are given below:

Properties:

• Wrinkle resistance
• Heat resistance
• Good mechanical properties
• Polymerization and cross linking is possible
• Thixotropic properties
• Azeotrophe esterification is possible
• Alcoholic transesterification is possible
• Thermoplastic qualities
• Combustible at high temperatures
• Thermosetting property
• Cross linking and polymerization is possible through exothermic reactions

Application of Polyester:

• Widely used in apparels
• Fiberfill is used in cushion padding, comforters and in stuff pillows
• Woven polyester fabric is used in home furnishing
• Medical Implants
• In jet engines as abradable seal
• Spun together with natural fibres to give strength
• Useful in making of films and bottles
• Also useful in holograms, liquid crystal displays, filters and tarpaulin
• Useful in insulating tapes, film insulation for wire and dielectric film for capacitors
• In auto-body fillers, casting materials and fibreglass laminating resins (because of thermosetting property)
• Useful in finishing of high quality wooden products
