The composition of PVC Windows

The main raw material for the manufacture of a window profile is polyvinyl chloride. In addition, it includes various additives to give the plastic the necessary properties. Thanks to special modifiers, stabilizers, antioxidants and other groups of substances plastic gets the characteristics of durability, strength, dimensional stability and color. 

All the manufacturers of profile are the owners of the unique recipe that is a production secret and strictly guarded. However, there are certain proportions which all manufacturers more or less adhere. Sometimes to reduce the cost, manufacturer increases the mass fraction of filler in the composition of profile. The cheapest additive is hydrophobic chalk and if it is added quite a lot, the cost will be naturally lower. But the more chalk in the composition, the more brittle and less durable will be the profile. 

The composition of the standard window profile includes from 5 to 10 parts of chalk. This profile will be high quality and durable. Recently, in connection with the protracted crisis, many companies are changing the classic recipe in the direction of increasing the mass fraction of chalk to the detriment of the consumer characteristics of the product. Profiles of unknown brands are not afraid to spoil the reputation and focused on quick profit, so they are willing to reduce the quality of the product in order to sell it cheaper. Well-known large companies such as Deceuninck are not ready to compromise at the expense of quality. By purchasing products from this profile, you can be sure that they meet the stated specifications. Buying windows, do not forget to know what brand of profile they are made.
