Polypropylene is a common thermoplastic that is used in many different industries and for many different types of parts and components. Its chemical structure is partially crystalline, which means it has a hardness and an increased resistance to heat that the non-crystalline types of polymers.
In its natural state, polypropylene is white, and it is typically left that way for use in polypropylene valves. This is a plastic that is naturally resistant to many types of chemicals including organic solvents and solutions that include organic salts, acids as well as bases.
In most applications, polypropylene valves are selected due to their corrosion and chemical resistance as well as their durability. By coating the wetted surface of the valves with PTFE polytetrafluoroethylene, the valve can be further enhanced with regards to corrosion resistance, making it an ideal option in high purity types of systems or when there are very aggressive types of media.
Lightweight Valves
In corrosive types of environments, these valves outperform metal valves, and they do not give up any strength or durability to their metal counterparts. They can be precisely molded and produced, allowing for easy installation. With this ease of installation and precision design, they are also able to create a complete seal, eliminating the risk of leaks through the system while also remaining mechanically operable even if not used for long periods of time.
Through the molding process used to manufacture the polypropylene valves, joints are completely eliminated. This also prevents the risk of failure in these areas, even in high-pressure applications or when there may be thermal changes in the system.
The choice of polypropylene is also a good selection for a long-lasting valve. These valves require no maintenance once installed and can be found in standard, miniature, and custom sizes and configurations in all valve types.
