NBR
It is suggested for the biggest part of sealing applications and it has a very common use. Nitrile (NBR) is a Butadiene - Acrylo Nitrile (ACN) is a polymer. At Kastas A.S., the percentage of acrylo nitrile in the nitrile compound varies between 30% and 50%. The variation in the percentage of ACN changes the volume, gas permeability, elasticity and compression set of the compound used in mineral oils, grease and fuel. Nitrile is very durable against aliphatic hydrocarbons (i.e. propane, butane, petroleum etc.), mineral oils (lubricants, H, HL, HLP type of hydraulic oils), greases, HFA, HFB, HFC, type hydraulic fluids, vegetal-animal oils, light heating oil and diesel oil. For fuels and industrial fluids, different mixtures are prepared. Our standard nitrile compound is recommended to be used between -30°C and +105°C. For short period of applications, it can be increased to +120°C.

H-NBR
It is a kind of elastomer which is made in such a way that a part or complete part of NBR polymer is hydrogenized with double linked Butadien. Vulcanized with Peroxide HNBR has durability against high temperature and oxidation. Having higher temperature resistance and mechanical values than standart NBR compound, HNBR is suggested for the temperature range -30 and +150°C.

NBR -FDA

It is a white Nitrile Butadiene Rubber commonly referred to as NBR, Nitrile or BUNA. Good physical characteristics and chemical resistance to the most common hydraulic fluids makes NBR an excellent sealing material. NBR materials are one of the most used elastomers in sealing applications.NBR-FDA N111 – white is approved for the use of applications in contact with foodstuff.
