Mechanical Seal Fluoroelastomer 1.5mm FKM Flat Gasket
Customized And Standard Fluoroelastomer machinary sealing Rubber FKM Flat Gasket
Description:
Fluorine rubber has high temperature resistance, can be used in the environment of -30℃－+250℃, resistant to strong oxidant, oil, acid and alkali. Usually used in high temperature, high vacuum and high pressure environments, but also suitable for oily environments.
Due to its various excellent properties, fluorine rubber is widely used in petroleum, chemical, aviation, aerospace and other sectors. Special fluorine rubber can reach a temperature of -50℃--+300℃,
and can be customized according to customer requirements.
Material:
Fluorine rubber FKM A is the main material, but it is not limited to this. Special fluorine rubber such as FKM B and FKM GF can be customized
according to the comprehensive use conditions of customers.
Feature:
High temperature resistance, acid and alkali resistance, fuel oil resistance, resistance to various chemical solvents, etc.
Operating temperature range:-30℃－+250℃
Size:
Common specification of rubber gasket :DN15 ~ DN400 The thickness of 1mm, 1.5mm, 1.8mm, 2mm, 2.5mm, 3mm, etc. can be opened by drawing
Application:
Rubber gaskets have oil resistance, acid and alkali resistance, cold and heat resistance, aging resistance and other properties.
Sealing gaskets that can be directly cut into various shapes can also be mass-molded through standard molds.
They are widely used in medicine, electronics, chemicals, and antistatic , Flame retardant, food and other industries.
