Compared with acrylic binders, polyester resin has the following advantages.
1 Less Consumption
The highest strength on yarn for the acrylic binder is 650 grams per centimeter square, while for polyester resin it is 1000 grams. So for the same amount of yarn, the resin has less consumption.
2 Lower Price
The raw material cost of polyester is always much cheaper than acrylic monomers. And it is a forever applicable formula. So polyester resin has a much lower price.
3 More Convenient Transportation
The acrylic chemical is in liquid form and polyester is in solid form. So the latter one is more convenient for transportation, especially overseas one. And at the same time, solid form has a lower transportation charge.
