All about polyester resin properties & uses

A Guide to Polyester Resin Properties and Usesz

• Polyester resin is formed through the reaction of
  dibasic organic acids with polyhydric alcohols.
  Their application can be recognized in the
  industrial setting as components of sheet and
  bulk moulding compounds and commercially as
  toners for laser printers. Commonly, Polyester
  resin is fused with fiberglass to produce
  low-maintenance wall panels often used in
  restaurants, restrooms or the kitchen.
• As a fact, polyester resin for FRP reign superior
  in chemical, mechanical and electrical abilities
  that form part of their properties. But setbacks
  of the same are their fragile nature and limited
  durability. For these reasons they are only
  suitable in construction of light weight
  materials. Now we look at the subdivisions
  polyester resin fall in which include the
  saturated or the unsaturated type.

• The unsaturated types come out as the more
  popular of the two. They are versatile in nature
  formed through the reaction of aromatic acids
  with a mixture of glycols and maleic anhydride.
  From this chemical reaction unsaturated polyester
  resin is born, with great production efficiency
  and attractive coloring to add to that. They have
  unparalleled strength compared to the saturated
  resins with great resistance to chemicals and
  heat. When induced on glass fiber they form
  excellent Fiber Reinforced Plastics or FRP the
  common abbreviation.
• The unique and advantaged properties of the
  unsaturated polyester resin give them an upper
  hand in household, industrial and automobile
  applications. For starters, they are used in
  water proof pans, wall panels and ceiling panels.
  For an exquisite home décor, unsaturated
  polyester resin is the trick used in decorated
  panels for the walls.

• The heat resistance abilities of unsaturated
  polyester resins get a go ahead from automobile
  engineers in the production of air spoiler, front
  panels and engine covers. They also form part of
  the ceiling covers for cars and window frame
  covers.
• Away from the automobile arena, unsaturated
  polyester resin has approval in producing circuit
  breakers for electrical appliances. Moreover,
  they are also the components used in telephone
  boxes, dish antennas and light covers. Lastly,
  unsaturated Polyester resin is credited with the
  manufacture of DVD trays and honeycomb bases. Not
  forgetting LCD projectors and optical units.

• The saturated type doesnt have much
  consideration in our day to day application.
  Formed from the polycondensation reaction of
  multifunctional organic acids and multihydroxy
  alcohols, they can only be used as powered
  coatings. But the powdered coating is gaining
  popularity and becoming widely used throughout
  the world. They do a commendable job in hybrid
  systems when combined with the equally efficient
  epoxy resins. Saturated polyester resins are also
  applicable in structures hardened with primid, a
  substance made of hydroxyalkylamide and acts as a
  cross linker of the powdered resins.
• Saturated polyester resin may not match the
  popularity of the unsaturated resins but they are
  also highly recognized for their eco-friendly
  trait. They are proficient in eradicating organic
  solvent proven by experts to be harmful to the
  environment. Painting work is also economical
  thanks to saturated resins. When mixed with
  regular paint it makes it possible to apply thin
  layers of paint to surfaces thus saving a lot on
  the quantity of paint you buy.
