What's Each Rubber's Typical Features ?
NBR Rubber Features:
Nitrile rubber (NBR, Buna-N) provides excellent resistance to
petroleum oils as well as mineral and vegetable oil. Nitrile rubber
also offers strong resistance to heat aging - often a key advantage
over natural rubber.
Nitrile rubber performs well in carburetor and fuel pump
diaphragms, aircraft hoses, seals and gaskets as well as oil-lined
tubing. Due to its versatility, nitrile is used in applications
involving not only oil and fuel resistance, but those applications
requiring resistance to heat, abrasion, water, and gas
permeability.
FKM Rubber Features:
Viton belongs to the Fluoroelastomers (FKM/FPM) group of rubber
compounds. There are many grades and hardness variations to solve
most applications with various formulations to meet specific
requirements of temperature and chemical resistance. Typical uses
include:excellent heat resistance,good mechanical properties,good
compression set resistance,resistance to wide range of oils and
fuels,resistance to solvents; especially all aliphatic, aromatic
and halogenated hydrocarbons and acids.
EPDM Rubber Features:
EPDM rubber is a high density rubber primarily used for outdoor
applications. It has dynamic and mechanical properties between
natural rubber and synthetic rubber.
Do not use EPDM if continual contact with petroleum based products
is required.
Not recommended for usage in food applications or those that are
exposed to aromatic hydrocarbons.
HNBR Rubber Features:
Hydrogenated Nitrile Butadiene Rubber (HNBR), also known as Highly
SaturatedNitrile (HSN), is special class of nitrile rubber (NBR)
that has been hydrogenated to increase saturation of the butadiene
segment of the carbon polymer backbone. Subsequent improvements to
the material properties, over that of a nitrile rubber (NBR),
include greater thermal stability, broader chemical resistance, and
greater tensile strength.
HNBR is classified by ASTM as a DH-type polymer. This
classification indicates 150ºC service temperature as well as less
than 30% swell in IRM 903 oil. HNBR can be formulated to meet
application temperatures ranging between -50°C and 165ºC.
SBR Rubber Features:
1.Main materials: Styrene-butadiene rubber (SBR), a general-purpose
synthetic rubber,produced from a copolymer of styrene and
butadiene. Exceeding all other synthetic rubbers in consumption,
SBR is used in great quantities in automobile and truck tires,
generally as an abrasion-resistant replacement for natural rubber
(produced from polyisoprene).
2.Available place: They are widely used in automobile, electrical
appliances, building vibration isolation and other industry. For
example, air blower, water pump, instrument, measuring of ships and
so on.
3.Main performance: SBR has similar chemical and physical
properties to natural rubber, with generally better abrasion
resistance,outstanding strength,good creep and stress relaxation
resistance and low cost,etc. It is not recommended to use SBR in
applications that involve ozone, strong acids, oils, greases, fats
and most hydrocarbons.
Neoprene Rubber Features:
Neoprene Rubber, also known as neoprene polychloroprene, is an
extremely versatile synthetic rubber with more than 75 years of
proven performance.
In the automotive world, neoprene is used for many under-the-hood
and underbody parts that require a reasonably priced,
mid-performance polymer with a good all-around balance of
performance properties.
Natural Rubber Features:
Natural rubber was originally derived from latex found in the sap
of rubber trees. The purified form of natural rubber can also be
produced synthetically. Natural rubber is an ideal polymer for
dynamic or static engineering applications.
Caution: Natural rubber is not recommended for applications where
the rubber part will be exposed to ozone, oils, or solvents.
PU/Polyurethane Rubber Features:
Polyurethane is an organic polymer. Polyurethanes are formed by
reacting a polyol (an alcohol with more than two reactive hydroxyl
groups per molecule) with a diisocyanate or a polymeric isocyanate
in the presence of suitable catalysts and additives. Polyurethane
is a widely used compound due to its superior strength, tear and
abrasion resistance. Polyurethane also provides excellent
permeation resistance.
Features:
- Good hydraulic oil and gasoline resistance
- Resistant to pure aliphatic hydrocarbons (propane, butane, fuel)
- Resistance to mineral and silicone oils and greases
- Resistant to water, oxygen, ozone and aging
- Excellent tear and abrasion resistance
- Available in multiple types and compounds to meet performance and
cost requirements
