O-ring advantage:
O-rings have the following advantages compared to other types of
seals:
-- Suitable for a variety of sealing forms: static seal, dynamic
seal
Suitable for a variety of materials, sizes and grooves have been
standardized, interchangeable
- Suitable for a variety of sports: rotary motion, axial
reciprocating motion or combined motion (such as
rotary reciprocating combined motion)
- Suitable for many different sealing media: oil, water, gas,
chemical media or other mixed media
Effective sealing of oil, water, air, gas and various chemical
media through the selection of suitable rubber
materials and appropriate formulation design. The temperature range
is wide (-60 ° C ~ +220 ° C), the
pressure can be up to 1500Kg / cm2 when used in fixed use (combined
with the reinforcing ring).
--Simple design, compact structure, easy to assemble and
disassemble
The O-ring cross-section structure is extremely simple, and has a
self-sealing effect, and the sealing performance
is reliable.
Since the O-ring itself and the mounting structure are extremely
simple and standardized, installation and
replacement are very easy.
--More varieties of materials
Can be selected according to different fluids: nitrile rubber
(NBR), fluororubber (FKM), silicone rubber (VMQ),
ethylene propylene rubber (EPDM), neoprene (CR), butyl rubber (BU),
poly Tetrafluoroethylene (PTFE), natural
rubber (NR), etc.
--low cost
--The dynamic friction resistance is relatively small
FKM Rubber Material O-Ring Seals
FKM is a copolymer made of highly fluorinated hydrocarbons and
developed during the 1950s. FKM
seals display very good resistance to media, ozone and aging. The
material is also stable in fuels as
well as petroleum-based oils and greases, along with aliphatic and
aromatic hydrocarbons.
It is unstable with regard to polar solvents (e.g. MEK and ethyl
acetate), low molecular
weight organic acids (formic and acetic acid), glycol-based brake
fluid, ammonia gas, amines, alkalis
and superheated steam. There are copolymers, terpolymers and
tetrapolymers with fluorine content
varying between 65 and 71 percent. In this way, FKM can be
precisely designed for specific requirements
in terms of media resistance and cold flexibility. This is a
benefit that, in particular, reliably protects
applications in the chemical and pharmaceutical industries that have aggressive media and process
temperatures of above 140 °C, which materials such as EPDM or HNBR
cannot handle.
As a peroxide-crosslinked material, the newly developed 75 FKM
239961 from Freudenberg Sealing
Technologies meets the latest regulatory requirements for materials
in the food, beverage and
pharmaceutical industries with direct product contact. Its very
high purity, media and temperature
resistance are also quite impressive, enabling it to be used as a
static or dynamic seal in a wide range
of applications. O-rings and diaphragms can now be manufactured
from this material. In fact, customer
-specific molded parts will also be possible in the future. Due to
its clean structure, the material also
fulfills all necessary certifications in the long term, such as EU
(Reg.) 1935/2004, FDA § 177.2600,
USP Chapter 87 (in vitro), USP Class VI Chapter 88 (currently in
process), ADI free, BfR XXI (Cat. 4)
and 3-A® Sanitary Standards.
We can supply material as NBR, FKM, SIL, EPDM, CR, NR, PU, HNBR,
FFKM, ACM ,SBR ,
FLS(FVMQ) , etc...
Different elastomers have different compatibility with various
chemical elements and their characteristics.
