Get priceThe process of creating PCDT polyester is similar to the process of creating PET polyester, but this polyester variant has a different chemical structure. While PCDT also consists of ethylene glycol reacted with dimethyl terephthalate, different production processes are used to make these two common polyester variations.
Get pricePolyester is a manmade fibre, synthesized from petrochemical products by a process called polymerization. Polyester is derived from crude oil petroleum and is a non- renewable resource. It is processed through a system called ‘cracking’ which treats the petroleum though intensive heating and cooling, fuel, solvents, pressure and catalysts to break down the molecular structure.

Get pricePolyester resins are thermosetting and, as with other resins, cure exothermically. The use of excessive initiator especially with a catalyst present can, therefore, cause charring or even ignition during the curing process. Excessive catalyst may also cause the
Get priceTypically polyester fibres are produced as continuous filaments either from a granulated polymer (batch process) or by a continuous polymerisation. In the batch process granules are first dried at a temperature of about 170°C in order to reduce the moisture content and thus prevent the hydrolysis of the polymer which leads to the deterioration of its properties.
