Polyester resins: properties, application, features of work

Polyester resin has a fairly broad scope.application. These products are obtained by chemical production due to a certain complex process of combining and processing the relevant substances. The composition of the polyester resin are alcohols, they are formed as a result of oil refineries. Read more about polyester resins. here.

These are glycols, (for example, monoethylene glycol,diethylene, triethylene, propylene, butylene), as well as glycerin, pentaerythritol, xylitol. Acids: orthophthalic, adipic, sebacic, terephthalic, maleic anhydride, including methacrylic and acrylic acid. If necessary, modification of polyester resins have options for the use of vegetable oils and fats, as well as resin acids.

With the use of this product produce a variety of products. These are hulls for boats, as well as many details for them, such as bathrooms, surfboards, etc.

Such compositions have received their use invarious areas of production, in the manufacture of products resistant to chemicals. They showed themselves well in the production of tourist and sports equipment, as well as in the creation of sanitary accessories, for example, many have heard the concept of acrylic bath or acrylic shower tray, etc.

Polyester resins have excellent quality characteristics. These include:

• resistance to any temperature changes (temperature ranges from 60 to 100 degrees);
• unique high resistance to mechanical stress (after complete solidification has a huge level of strength and hardness);
• resistance to chemical substances (except industrial);
• wear resistance and long service life of polyester resin products, while the initial quality characteristics do not decrease at all;
• products from a similar material virtually eliminate shrinkage.

Working with a substance like polyester resindoes not cause complexity and does not require great professionalism and experience. The main thing is to observe the basic safety rules in working with this composition and take into account certain nuances. For example, in order for the resin to freeze during the process, and the final product to have the properties of strength and reliability described above, it is necessary to use special hardeners.

Also note that after mixing the resin withhardener should work quickly, so as not to begin the process of exothermic reaction. After applying the substance, it is necessary to give it as much time as possible to solidify and take the desired shape.

If you are interested in purchasing such products, you need to take seriously supplier selection. He must provide all the necessarycertificates for your product. Then you will be assured of its high quality. After all, quality is of decisive importance for us. And to such products as polyester resins, increased demands. That is why you need to take seriously the issue of their purchase.
