What is Polyester Resin?

Polyester resins, together with glass fiber reinforcements, are the main components used in composite production. It is one of the basic building blocks of the composites industry as it is used in many applications. The general properties of these resins are as follows:

It is empowering.
It is a durable polymer composite product. It is therefore used for different applications.
It is commonly used in the form of unsaturated resin.
It has synthetic copolymer properties.
There are 3 types of orthophthalic polyester, isophthalic polyester and terephthalic polyester.
It has fast curing properties and is easy to use.
They are the main matrix materials of polymer composites with their thermal stability and chemical resistant properties.
Because of its low cost, it is used in the production of a wide range of composite parts.
Suitable for closed molding processes such as resin transfer molding, compression molding, vacuum infusion process and pultrusion. It is also suitable for open molding.

Polyester resin is one of the composite components with these properties. It is used in various fields thanks to its chemical resistance, durability and lightness. As it is a versatile polymer material, it is widely preferred today.

General Purpose Polyesters

Polyester, composed of the words “poly” and “ester”, means “a large number of organic salts”. First time 2. The unsaturated polyester resin used in World War II was reinforced with glass fiber in 1950. Thus, it was discovered to be a very strong and light material. Today, polyesters are more durable and have improved properties compared to their original form.

General purpose polyester resins in the thermoset group are obtained as a result of the condensation reaction of dibasic acids and polyhydric alcohols. General purpose polyesters are popular because they are multi-purpose. The fact that these general-purpose materials are available in plastic, fiber and resin forms makes it possible to choose them for different uses. For example, general purpose materials are used in the packaging industry in the form of plastics, in the textile industry in the form of fibers and in the construction industry in the form of resins.

Uses of Polyester Resins

Polyester resins are used as a useful material in various fields as they are available in many forms. The reason why this material is preferred for different areas such as design, construction and architecture is that it is light and durable. In general, these resins have the following uses:

Construction materials: Construction is where these resins are widely used. It is mainly used for cladding, cladding panels, roofing tiles and pipes for prefabricated buildings. It also has a suitable use in bathroom furniture.
Packaging and luggage: In film form, these resins can be used as a highly capable packaging material. For this reason, they are reinforced with leather and fabric for briefcases, suitcases and similar items.
Ship and boat parts: Due to its water and moisture resistance, it is used in the construction of ship and boat parts. It is used in marine vessels, preferred in boat hulls and lamination applications.
Automotive sector: Used in the automotive sector for repair and restoration, auto repair and auto care products and vehicle surface coatings.

The use of polyester resin extends from the industrial field to everyday life. Since it has a versatile use, it is processed in composite production and produced in different shapes.
