What is Polyester?
Polyester ? Any of numerous synthetic polymers
produced mainly by reaction of dibasic acids
with dihydric alcohols
  • Polyester classification
  • Saturated Polyester
  • PET(polyethylene terephthalate) fiber, film,
    bottle
  • PTT(polytrimethylene terephthalate) fiber
  • PBT(polybutylene terephthalate) engineering

Control factors of Reaction
O R-C-OH R'-OH
O R-C-O-R' H2O
- rate of ester formation 1. reactivity of the
functional groups ( for -OH primary, secondary,
tertiary) 2. solubility of reactants 3. reaction
temperature 4. relative proportions of
reactants 5. inclusion of catalyst 6. reverse
reaction water of reaction should be removed
10
Row Material Selection(1)
"Hard" raw materials - short chains -
aromatic rings - cycloaliphatic structure
nature of cross-linking agent plays a key role
in the final hardness of the coating
"Soft" raw materials - long aliphatic chains
HOOCCH2CH2CH2CH2COOH AdA HOCH2CH2CH2CH2CH2CH
2OH 1,6-HD
11
Row Material Selection(2)
Hydroxyl Functional raw materials -
triols.. (TMP etc.) - lower reactivity
. higher stoving temperature ??high
energy consumption . higher addition
levels of catalyst
Carboxylic acid Functional raw materials
- for water soluble polymer . to
provide acidic site for neutralization by amines

SKYBON Product Line-Up
ES Solvent-borne type
ET Toner Resin
EW Water-borne type
EH Hotmelt type
Thermoplastic resin used by dispersing with
organic solvent. Widely used as a main binder for
coatings, inks and adhesives.
Water-soluble thermoplastic resin used for
textile sizing or as water soluble coating,
water-based paint, inks and adhesives.
100 non-volatile thermoplastic resin and
maintains solidity in high temperatures without
containing any water or organic solvent.
Thermoplastic resin for toner of laser printer
and copier because of Its excellent
fusing property at low temp- rature. It can be
applied to high speed machine.
