Companies that deal with the production of technical seals have their hands full. There is a great deal of demand for this type of seal. They are used in every industry, construction, automotive, electric and even in the aerospace industry. Technical seals are made of, among others, silicone, latex and, of course, rubber. The production of these components takes place in the process of pressure vulcanization. Of course, we have many new technical solutions, such as special injection molding machines, where production is carried out by injection.
When it comes to vulcanization of technical seals, it is based on a process in which the so-called “ spikes ” are formed between polymer molecules (i.e. a chemical substance with a very high molecular weight). bridges. This leads to the formation of a three-dimensional supermolecular network and ultimately to the formation of rubber. This method is the vulcanization of unsaturated polymers at elevated temperature and pressure (240 – 280 degrees Celsius, 100 – 300 MPa), without the use of chemical vulcanization agents.
