Resin Selection Options
One of the most important elements of plastic random packing is the quality of the resin from which it is made. KemFlo manufactures its plastic random packing utilizing the highest quality resins on the market. All of our resins can be traced back to the specific origin and batch. This ensures that our customers receive quality packing that will perform per their specification. There are many things to consider when choosing the best resin for your specific application. Chemical environment, temperature, vessel size, and pressure drop are major considerations when selecting a resin for your plastic random packing. Some resins offer superior chemical resistance and temperature resistance over other general purpose resins. Kemflo manufactures their Kempac packing is a variety of resins including Polypropylene, Polypropylene with glass, NSF approved Polypropylene, PVC, CPVC, PVDF (Kynar), ETFE (Tefzel), PFA (Teflon), Halar and more resins available upon request. KemFlo is one of the only manufacturers of plastic tower packing who offers NSF approved Polypropylene resin for applications that involve potable water, food processing or pharmaceutical processes. In order to offer NSF approved resins KemFlo must meet stringent requirements including regular auditing and inspections of our manufacturing facility. Below is a list of some of the more common plastic resins available.
|Material||Service Temperature (F)|
|Polypropylene Glass Filled (PP-G)||210–250*|
Whether your process involves air scrubbing (the removal of a contaminate from a gas stream) or air stripping (the removal of a contaminate from a liquid stream) it is important to closely evaluate your system’s process data. List the contaminates entering the systems inlet in parts per million. Then list the same contaminates and their expected parts per million at the outlet of the system. Knowing all of the contaminates in a system and their amounts is extremely important in determining what resins are compatible for your application. Equally important is to know the maximum operating temperature of your system and whether there may be temperature spikes. The combination of chemical contaminates and temperature is key in evaluating resin options. All resin manufactures publish a chemical resistant guide for the resins that they manufacture. The presence of solvents, acids, free radicals, and oxidants needs to be considered as well as the pressure in the system. All of KemFlo’s Kempac plastic tower packing product line including the Tri-Pack, Pall Ring and Plastic Saddles are offered in a variety of resins to meet your specific requirement. Custom resins and other resins not listed above may also be available upon request.
Selecting the best resin for your plastic tower packing and other internals can optimize the performance and extend the life of the entire system. Maximizing your investment in an air scrubber or air stripper is the goal of every facility. By selecting the proper material for your system, you can reduce maintenance cost and extend the life of the plastic random packing.
