Effect of Chemical Exposure On Polyvinyl Chloride (PVC)
The following list is a general reference guide for chemical exposure on PVC that we use in our custom profile extrusions in Plainwell, MI and Louisville, KY. These references are made with the assumption that the chemical contact with this material is casual as opposed to continuous or immersion service.
The ratings are to be used as a guide in selecting the most suitable product for a specific extrusion application at a standard temperature and pressure. Most powders, in general, present very little problem for PVC. Every application is different. In some cases there may be discoloration of PVC due to the exposure to certain compounds, chemicals, and solvents. Each user should conduct their own tests to determine the suitability of the raw material for a specific application. Although it is believable the attached ratings are correct and reliable, no performance guarantee is expressed or implied.
