Plasticizers are substances that are added to other substances to affect the physical properties of the final product (or the physical properties of a particular substance during the manufacturing process). For people who are little oriented in the world of plasticizers, the term plasticizer can be associated primarily with the use of plasticizers in construction, because it is a common way to influence the quality of masonry and plastering mortars. Of course, plasticizers are successfully used in many industries. In which? We answer this question below.
Meanwhile, the main application of plasticizers is the plastics industry (for example made on the basis of PVC). This is for example the production of gaskets, cables or pipes. In addition, plasticizers are very often added to rubber products (affect on stretch and elasticity).
An interesting example of the use of plasticizers is the pharmaceutical industry. Plasticizers play the role of solvents and are sometimes used as a material preventing cracking of capsules in coated tablets.
In the construction industry, in addition to the above-mentioned application (addition to mortar and plaster), plasticizers are added to varnish and paint. In the case of concrete mortars, the plasticizer means that the mortar has less water demand, dries faster or is more resistant to external factors (e.g. frost). However, in the case of varnishes and paints, thanks to the correct plasticizer you can increase the resistance to cracking and chipping. Another interesting example is the production of glue, because the correct use of a plasticizer can affect the strength and life of the glue.
In summary, plasticizers are substances with a very wide use. First of all, they are used in the production of materials made of PVC and rubber and in the construction industry. However, they can also be found in other areas (e.g. in medicine).
