NBR - characterized by high resistance to oils, fuels and chemicals. NBR vulcanizates have high tensile strength and elasticity and low compressive strength. Temperature resistance up to 100oC.
SBR - quite high abrasion resistance compared to NBR. Resistance to many non-polar solvents and diluted acids and bases. Hydrocarbons and fats undergo large swelling. Low temperature resistance - up to 80oC. SBR rubber has medium resistance to atmospheric agents and ozone.
EPDM - resistant to light, heat, oxygen and ozone. Much higher resistance to heat aging compared to NR and SBR. Vulcanizates have excellent resistance to inorganic or highly polar liquids such as acids, alkalis and alcohols. EPDM has a low coefficient of abrasion and is a very good insulator and dielectric. Unfortunately, the resistance to organic solvents - aliphatic, aromatic and chlorinated hydrocarbons is very low.
NR - characterized by very good strength parameters including: tensile strength, rupture and tear. At low working temperatures it retains great flexibility.
IR - non-polar structure similar to NR does affect low resistance to non-polar factors such as: aliphatic, aromatic and chlorinated hydrocarbons. Isoprene rubber is also adversely affected by highly oxidizing substances (eg nitric acid, hydrogen peroxide ...). Good resistance to polar compounds: water, alcohols, glycols, acetone and dilute acids and bases. The advantage of IR is the small amount of heat generated during dynamic loads.
CR - has very good durability parameters combined with high resistance to temperature, ozone and environmental factors. Perfectly removes the internal heat generated during the dynamic loading of workpieces made of CR.
CSM - High resistance to thermal degradation and aging in particular ozone. Chromium atoms contained in rubber chains cause high light resistance and incombustibility of CSM products. The use of this rubber allows the vulcanisation to achieve the best flexibility in low temperatures, heat resistance and mechanical properties.
FKM - they are chemically passive both in the hostile environment and against the various organic liquids - oils and solvents. Low surface energy makes fluoride rubber self-lubricating. Fluorine atoms increase the temperature resistance to 350oC.
We produce parts and rubber coatings using the process of vulcanisation of semi-finished raw materials. Our products can be manufactured in hardness from 30 Sh'A to 95 Sh'A.
Rubber - the oldest and most widespread elastomer in the industry. The properties of a particular rubber depend on the type of base component used - NBR, SBR, EPDM, NR, IR, CR, CSM, FKM. Each of the given rubbers is characterized by its specific properties.
Rubber elastomers have intermediate strengths between polyurethane and silicone (10 times less than polyurethane / 10 times stronger than silicone).
