What is the material of fkm? What's the difference between FKM and FPM?

FKM is the abbreviation of fluororubber, which can be divided into three basic types: fluorocarbon rubber, fluorosilicone rubber and fluorinated phosphazene rubber.

Difference:

1, different classifications

Fluorine rubber is a special synthetic elastomer, and the carbon atoms in its main chain or side chain are connected with fluorine atoms with strong electronegativity.

FPM is the abbreviation of Fast Page Mode, which is widely used in 486 and early Pentium era. It transmits data every three clock cycles.

2. Different characteristics

Fluoro-rubber micropowder is a kind of powdered fluororubber material, which is produced by using carefully selected FKM industrial by-products as raw materials and adopting patented technology-wet conversion process.

FPM (Refine Pointset Method) is a new generation of meshless computational fluid dynamics software, a meshless particle CFD numerical method, and represents the latest development direction of fluid numerical simulation.

3. Different functions

The fluororubber seal is especially suitable for environments requiring high temperature and high chemical stability. Aiming at the special environment such as high additive lubricating oil, Mo developed a special FKM mixture.

The biggest difference between FPM (finite point set method) and traditional numerical methods (such as finite element method, finite volume method and finite difference method). ) is a necessary mesh division without discretization of differential equations.
