Advantages and disadvantages of unsaturated resins Unsaturated polyester resin, whose molecular structure contains non-aromatic unsaturated bonds, can be used to initiate a crosslinking reaction with an appropriate initiator to become a thermosetting plastic. Unsaturated polyester molecules are long-chain mole...
WHAT ARE THE ADVANTAGES AND DISADVANTAGES OF POLYESTER FABRIC? Polyester is one of the world’s most popular synthetic polymer materials, demonstrating a wide variety of advantages over other industrial fibers. When considering the many benefits that polyester offers, know that we have the people an...
Both PVC steel wire hoses and TPU steel wire hoses have their advantages and disadvantages. The choice between the two will depend on the specific application requirements. PVC hoses are more affordable and flexible, but they have a lower working temperature range and are not as durable....
Samples containing different contents of NiCFs (1 and 4 wt%) and constant contents of MWCNTs and SCFs were manufactured and tested. A detailed list of the specimens is reported in Table 1. The matrix used was an unsaturated polyester resin (1629 NT from Lonza). The SFCs used were obtained...

Encapsulated through Polyester Film & Epoxy Resin The advantages of Polyester capacitors include the following. Accuracy Better Environmental Adaptability Loss Angle Reliability Insulation Resistance Temperature Characteristics Polyester Capacitor Applications ...
terephthalic acid has two major disadvantages. In this regard, it tends to impair the solubility of the polyester resin in common organic solvents. It also causes the resin to crystallize out of solution in a relatively short period of time. Consequently, conventional polyester resins prepared for...
1. A method for recycling waste polyester resin, the method comprising: (b) depolymerizing waste polyester resin; (b) polycondensing the depolymerized product from step (a) with a polyhydric alcohol to provide a polyester polymer having an acid value of 10-150 mgKOH/g; and (c) recoveri...
