The Chemical resistanceof plastic piping is basically a function of the thermoplastic material and the compounding components. In general, the lesscompounding components used the better the Chemical Resistance . Thermoplastic pipes with significant filler percentagesmay be susceptible to Chemical attack where an unfilled material may be affected to a lesser degree or not at newer piping products utilize a multi-layered (composite) construction.
ene and acrylonitrile. BUNA-N has good solvent, oil, water and hydraulic fluid resistance. It displays good compression set, abrasion resistance and tensile strength. BUNA-N should not be used in highly polar solvents such as acetone and methyl ethyl ketone, nor should it be used in chlorinated hydrocarbons, ozone or nitro hydrocarbons.
