WHAT IS THE RUBBER ?
Rubber is an elastic material that can be manufactured by petrol, natural gas (synthetic rubber) and water of tropical plants (latex) (natural rubber).
Rubber usage most early known as Azlek people in 15 th century, in 1493 Kristof Kolomb has discovered New World and mentioned about Azlek people playing with boll made of lateks.
On the other hand, Rubber is introduced is introduced to our life by Charles Goodyear who in known as the father of rubber.
Characteristic of Rubber
NBR (Acrylonitrile Rubber) : NBR is type of Acrylonitrile It is resistant to aliphatic hydrocarbons, oils, greases and fuels. It’s heat resitnce is -30 °C, +120 °C
CR (Neoprene) : Neoprene ( CR) is resistant to tensile , tear and abrasion on the degree -45 °C to 130 °C . It is also resistant to flame ıt is also resistant to mineral oils, silicone oil, greases and alcohol . It is mostly prefered when ozone, fuel and oil resistant demanded all.
MVQ (Silicone) : Silicone rubber has elasticity between -50 °C to +200 °C . It is oxidised resistant to ozone and oil but it is so weak on dynamic application and some oxides, E.P type oils.
FKM (Viton) : This type of rubber is resistant to all types of grease, oil and solvent.
It is so resistant to most chemicals. It’s heat resistant is -30 °C, +225 °C.
PU( Polyurethane) : It is so resistant to heavy physical conditions (tear , abresion, wear) between the degree -30 °C, +100 °C. It is also resistant to mineral oils, greases and aliphatic hydrocarbons. . It is mostly used on pressure and active systems.
NR (Natural Rubber) : Natural rubbers heat resistance is -45 °C , 100 °C It is offered usage on elasticity needed systems.
SBR (Styrene Butadiene Rubbers) : It is resistant to glicol based brake oils, İnorganic acids, alcohol . It is resistant to glicol based brake oils, inorganic acids, alcohol. It is resistant to -45 °C and 100 °C. It is especially prefered for it’s cost. It is more cheaper than others.
EPDM (Etilen Propilene Diene Rubber) : It is especially used on ozone resistance necessary part. It is also so resistant to water, fosfat, ester type fluids, automotive brake oils and steam.
