ORK Customized Rubber Products Eco Friendly Hole Hard Solid Excellent High Temperature Resistance FKM Rubber Ball
Rubber Balls Provide Excellent Sealing in Flow Control Applications such as Pumps and Check- Valves.
Rubber balls are of various types depending on their area of applications. There are molded rubber balls,
precision ground balls which are manufactured as per exact specifications. The commercial grade rubber balls
are produced as per industrial requirements. Ther are sponge rubber balls, rubber cleaning balls, rubber balls
used in check valves and many more.
FKM Rubber Features:
Viton belongs to the Fluoroelastomers (FKM/FPM) group of rubber compounds. There are many grades and
hardness variations to solve most applications with various formulations to meet specific requirements of
temperature and chemical resistance. Typical uses include:excellent heat resistance,good mechanical properties,
good compression set resistance,resistance to wide range of oils and fuels,resistance to solvents; especially all
aliphatic, aromatic and halogenated hydrocarbons and acids.
