Due to its sample structure and reliable sealing performance , O-ring is the most widely used sealing production in static and dynamic environments.
It is used in Automotive industry, Construction industry, Electrical industry, Oil and chemical industry, Hydraulic & Pneumatic,Petrochemical,Aerospace, Semiconductor and mechanical industry.
FFKM polymer and its choosing
FFKM- Perfluorinated elastomer is copolymer of TFE and PMVE with a cure site monomer.
FFKM polymer is fully fluorinated backbones, so it has the highest level of chemical and thermal resistance in all rubber.
FFKM FFPM(Perfluoroelastomer)- Classification
Perfluorelastomers (FFKM) have high fluorine content from 70%~73%
Due to different cure site monomer in polymer, there are 3 types of FFKM curing system.
Perfluorelastomers (FFKM) have high fluorine content from 70%~73%
Due to different cure site monomer in polymer, there are 3 types of FFKM curing system.
Triazine, peroxide and bisphenol curable FFKM rubber.
The 3 types of FFKM has their own advantages and limitations and should be assessed their properties before using.
Choosing right FFKM raw gum/ compound will be the most important step to ensure optional sealing performance and service life.
Product Technical Property of FFKM raw gum
Below are comparison of different FFKM raw gum.
Due to different formulation and catalysts cause big difference in properties, please refer individual spec sheet for more information

Specifications and Models
Standard O-rings
O-ring is a round solid-rubber products that's designed leakage of liquids and gases media.
There are 2 dimensions in O-rings.
Inside diameter (ID) &
Cross section diameter (CS)
Custom molded shapes- rubber parts and rubber to matel Parts
To meet different environments and industry, there are many structure of sealing products.
Such as V-ring, X-ring and U-cup.
Besides rubber parts, there are also some rubber-metal parts.
Dimensions and mold are customized according to final requirements.
We manufacture O-rings in a wide range of sizes in multiple properties, such as color, hardness, compression set, tensile strength, temperature resistance and other chemical resistance.
Properties can be designed in rubber compounding.
But Dimensions should check one by one.
And it is better to provide CAD drawing.
Then our CNC department will produce mold accordingly.
Manufacturing process:
Clean room-make FFKM rubber compound
CNC workshop-customized mould
vulcanizing workshop- Molding rubber sealing parts
Rubber parts show
Standard and non-standard rubber parts and rubber-metal parts in sealing industry.
