Neoprene Rubber Gaskets
Neoprene is an all purpose polymer with many
desirable characteristics. It has additional
plus features: high resilience with low compression
set; flame resistance; compounds free of sulphur are
easily made; and animal and vegetable oil resistant
generally not affected by moderate chemicals, fats
greases and many oils and solvents.

EPDM Rubber Gaskets
Ethylene
Propylene is a polymer with outstanding properties.
It has exceptionally good weather aging and ozone
resistance; excellent water and chemical resistance;
excellent resistance to gas permeability, and
excellent resistance to aging due to exposure to
steam; and heat, resistance excellent up to 350
degrees F. Ethylene Propylene is a polymer
where oil and solvent resistance is poor, however,
it is fairly good in ketones and alcohols. It
is not recommended for food applications or exposure
to aromatic hydrocarbons. |

Nitrile Rubber Gaskets
Nitrile
(Buna-N) is a general purpose oil resistant polymer
which has good solvent. oil, water and hydraulic
fluid resistance, good compression set, abrasion
resistance and tensile strength. Nitrile
should not be used in highly polar solvents such as
acetone, and MEK, ozone, chlorinated hydrocarbons
and nitro hydrocarbons. |

|
White FDA Nitrile
Rubber Gaskets
White Nitrile sheet is made from FDA
approved ingredients per Z1 CFR 177.2600. It
also meets "3A Sanitary Standards for Multiple Use
Rubber and Rubber-like Materials used as product
contact surfaces in dailr equipment," number 18-01,
Class III ans IV. it has good resistance to
oily and greasy food products and abrasion.
This sheet is non-marking.W |

|
|
|
|
SBR Rubber Gaskets
SBR is a low cost non-oil
resistant material. It has good water
resistance and resiliency up to 70 durometer;
compression set becomes poorer with higher durometer;
generally satisfactory for most moderate chemicals
and wet or dry organic acids.
SBR is not recommended for ozone, strong acids,
oils, greases, fats and most hydrocarbons. |
|
|
|
|
|
Viton® Rubber Gaskets
(Fluorelastomer)
Viton® Fluoroelastomers have heat resistance up to 6000 degrees
F, and resistance to a wide range of oils and
solvents; especially all aliphatic, aromatic and
halogenated hydrocarbons, acids, animal and
vegetable oils.
Vi-Chem is not recommended for ketones, low
molecular weight esters and nitro containing
compounds. |
|
|
|
|
|
Silicone Rubber
Gaskets
Silicone
has a great many variations and can be
compounded to meet any number of applications.
Silicone can be compounded to have tensile in the
area of 1500 PSI and tear up to 200 lbs.; low
compression set and good resilience; moderate
solvent resistance; excellent heat resistance; good
release characteristics; extreme low temperature
properties; and can be highly resistant to oxidation
and ozone attack.
Silicone is generally attacked by most concentrated
solvents, oils, concentrated acids and dilute sodium
hydroxide. |
|
|
|
|
|
Butyl Rubber Gaskets
Butyl rubber
is impermeable to most common gasses and has good
resistance to sunlight and ozone. Butyl is
normally satisfactory when exposed to animal and
vegetable oils and oxidizing chemicals.
Butyl is not recommended for use with petroleum
solvent, coal tar and aromatic hydrocarbons. |
|
|
|
|
|
Gum Rubber Gaskets
Natural rubber
has many good characteristics. It has high
resilience, good compression set, food roll building
behavior, and molding properties; very good friction
surface, but not a fine smooth surface when ground;
high tear strength, low crack growth; usable for
ketones and alcohol; and good low temperature
properties.
Natural rubber is not recommended for oil and
solvent resistance and ozone attacks it |

|
|
|
Latex Rubber Gaskets
A 95% Pure
Natural Rubber manufactured fro fresh field latex.
Commonly used in slurry handling applications
including pipelines, chutes and tank linings,
hydro-cyclones and sumps. Latex offers high
abrasion resistance, tear resistance, impact
resistance, chemical resistance and electrical
resistance. |
|
|
|
|
|
Urethane Gaskets
Urethanes have
excellent abrasion resistance; good compression set
at high hardness levels; low friction surface;
tensile strengths up to 6000 PSI; good ozone
resistance; good oil and solvent resistance; and
poor heat and hot water resistance
|

Fluorosilicone Rubber
Gaskets
Fluorosilicone
is considerably more expensive than silicone,
however it is developed for special applications
where general resistance to oxidizing chemicals,
aromatic and chlorinated solvent bases is required.
Fluorosilicone is not recommended and is generally
attacked when exposed to brake fluids, hydrazine and
ketones. Fluorosilicone should not be confused
with silicone in regard to high heat resistance. |
