Rubbers
Artificial rubbers differ depending on which monomer they were made from.
For example, neoprene, chloroprene, ethylene-propylene and other rubbers are known.
Also, the classification of rubbers can be carried out according to their characteristics: the content of fillers (unfilled and filled), according to the final form (powdery, liquid), etc.
In terms of properties, rubber is very close to natural rubber and has a wide range of applications in the domestic industry.
So, pergut s 20 is suitable for the manufacture of a large number of mass products, can be included in the composition of adhesive joints.
Some types of rubbers are distinguished by their unique properties.
For example, silicone rubbers have a particularly high temperature resistance, which makes them suitable for the production of products intended for extreme operating conditions (aircraft tires, some types of industrial devices).
In our catalog we offer various types of synthetic rubbers, different in their properties and purpose.
All rubbers presented here are high-quality raw materials, produced in full compliance with accepted Russian and international standards.
