Random Packings
Plastic Random Packing
Plastic packings are used in corrosive applications with low to moderate operating temperature and can offer an economical advantage over metal materials. Where temperatures permit, plastic packings perform better than ceramic packings and are often less expensive than metals, particularly when exotic metals and alloys are required. Consequently, plastic packings are used mainly in absorption, scrubbing, stripping and heat transfer services.

Plastic packings are often preferred because of their lightweight construction and resistance to breakage. Further, the availability of numerous types of plastic resins provides the designer with a broad range of chemical and thermal resistant materials. our plastic packings are made in a wide variety of thermoplastic materials. Most of the packings are available in the materials listed in the table below. Other plastics are available by special request.
