Rubberized shafts are used in many industries, so rubber for them is selected on an individual basis. To rubberize shafts, enterprises use rubber, the basis of which is rubber of various types. Especially popular are rubbers with ebonites, the active component of which is styrene-butadiene rubbers. This type of rubber is highly resistant to acids, alkalis, wear resistance and withstands mechanical stress well.
- Hardness: 35-95 units of Shore A.
- Temperature range of use: 30-80C
Oil and petrol resistant coatings are produced from butadiene nitrile rubbers. These rubbers have good mechanical characteristics and high wear resistance.
- Hardness: 20-75 units. ShorA.
- Temperature range of use: 30-80C, and sometimes up to 140 C.
Rubbers based on ethylene-propylene rubbers are highly resistant to most hostile organic solvents, all kinds of oxidants and ultraviolet rays. Their mechanical properties are very good.
- Hardness: 45 - 80 units. ShorA.
- Temperature range of use: 25-80C.
It is worth noting that vulcanization of rubber is carried out both with the use of soot (carbon black) and without it. Those rubbers in which soot (carbon) is present - black, are distinguished by high mechanical strength, wear resistance, and electrical conductivity than those rubbers in which carbon is absent. Carbon-free rubbers are of light color, they are mainly used for those coatings when leaving any traces from the shaft is not desirable. Silicone rubbers are resistant to various aggressive substances, have high dielectric properties and can have different colors.
- Hardness: 35-80 units. ShorA.
- Temperature range of use: 60 - 280C, and sometimes up to 300C.
The rubber product used for the shafts meets all specifications. Rubber produced by the English company Excel Polyme is used for rubberizing the shafts of printing equipment. The resulting hardness of coatings varies from 20 to 30 units. Shor A. These rubbers have different colors as they are carbon free. During their work, their hardness, as well as physical and mechanical properties, do not change. There is no leakage of plasticizers from the rubber, in other words, the rubber coating of the shafts is not subject to cracking.
