What is polyester?
By getting to know more about these two products, we can get to know the difference between fiberglass and polyester. Polyester is a type of synthetic fiber. Polyester is used in various projects.
In explaining how polyester is produced in the simplest way, it can be said that this product is the result of the reaction of alcohol and acid in the laboratory environment. Polyesters are divided into two categories according to their molecular structure:
Saturated polyesters:
Saturated polyester molecules have a low weight and have a single and stable bond. Saturated polyesters are used to soften reactions and make adhesives that are heat resistant.
Unsaturated polyesters:
Unsaturated polyester molecules have a double bond in the structure of the polymer chain. The presence of this double bond makes it possible to cure polyester. This polyester model is used in reinforced plastics.
What is fiberglass?
In response to the question of what is fiberglass, it should be said that fiberglass is a type of polymer fiber like polyester. But the difference between fiberglass and polyester is in their basic structure. Fiberglass is also known as glass fiber.
This product is actually a combination of glass wool and several polymer materials including polyester, vinyl ester and epoxy. It is good to know that each of these resins is added to fiberglass to strengthen its strength. Of course, note that among all the resins used to produce fiberglass, polyester shows much less resistance to corrosion. . In contrast to epoxy resin, in addition to high resistance to corrosion, it will also be very strong against temperature changes.
Comparison of fiberglass and polyester
Before examining the difference between fiberglass and polyester, it is better in this section to compare fiberglass and polyester by setting some criteria such as the features and application of these two products.
Features
In spite of several differences between fiberglass and polyester, these two compounds have similarities in their characteristics. Durability and long life, affordability and high strength are among the common features of these two products. Also, the heat tolerance in both products is very high.
Application
The first and most common use of polyester that we are probably all familiar with is in the textile industry. Polyester is used to produce all kinds of fabrics for clothing, furniture and bed sheets. Also, polyester is used in the production of electronic products, packaging of all kinds of food and medicine, as well as making decorative containers and sculptures.
Comparing fiberglass and polyester, we realize that the variety of applications of this compound is more than that of polyester. Various forms of fiberglass sheets are used in various projects and industries, including automobile manufacturing, greenhouse construction, swimming pool construction, and various types of tanks and fireproof fabric production.
The difference between fiberglass and polyester
So far, we have fully familiarized ourselves with these two products. According to the things mentioned in the comparison of fiberglass and polyester, we realize that the difference between fiberglass and polyester can be summarized in several cases. The first case is naturally the structure of these two products. At the beginning of the article, we talked about the building materials and constituents of fiberglass and polyester. As a result, these two products are fundamentally different from each other despite some of the same applications.
Another point is the endurance of these two compounds. During a scientific experiment on fiberglass and polyester fabrics, the result was obtained that under the same tensile conditions, polyester fabric loses its original state to a greater extent. Another difference between fiberglass and polyester is their resistance in is equal to the blow. Due to the resins used in it, the structure of fiberglass has a higher resistance than polyester.
To check the truth of this claim, just hit two similar products made of fiberglass and polyester, such as decorative sculptures. . You will see that the polyester sculpture will break much faster and easier.
Another thing is the difference between fiberglass and polyester in terms of resistance to temperature changes. In this case, fiberglass shows better strength and durability. While polyester will undergo changes in appearance by continuous heating and cooling. We also talked about the difference between polycarbonate and fiberglass in previous articles.
