Unsaturated Polyester Resins Overview
What Is Polyester Resin?
Polyester resin is used in lots of industries. It is made when unsaturated dibasic acids or anhydrides react with glycols. This reaction makes a liquid resin with unsaturated double bonds. These bonds help the resin harden fast when you add a radical initiator like benzoyl peroxide. The resin gets strong at room temperature. You can use polyester resin to make fiberglass things because it sticks well to fillers and reinforcements.
Polyester resin has special features. You can see them in the table below:
| Property | Description |
|---|
| Corrosion Resistance | Stays strong against acids, alkalis, salts, and organic solvents. |
| Lightweight and High Strength | Weighs less than steel but is strong for cars and planes. |
| Excellent Thermal Performance | Keeps heat out, good for saving energy in buildings. |
| Processing Ease | Can be shaped at room temperature or with heat. |
| Electrical Properties | Works well for electrical insulation and sending microwaves.
|
Tip: Polyester resin hardens quickly and makes a tough surface. You can use it for many things that need to last.
There are some important chemical facts:
Made by condensation polymerization.
Has unsaturated double bonds for hardening.
Shrinks a bit when it gets hard.
Its chemical stability depends on ester bonds, which can break in acid or base.
This information shows why manufacturers pick polyester resin for many products.
Main Applications
Polyester resin is used in many fields. It has lots of uses. You can find it in construction, transportation, and daily life. The table below lists common uses:
