Caution should be used when comparing the chemical resis-tance properties of PVC Type I, PVC Type 11, PVC Clear, and CPVC as differences in chemical resistance exist. This technical note provides a basic resistance rating for many chemicals. Effects of Chemicals on Plastics Chemicals can affect the strength, flexibility, surface appearance, color, %PDF-1. CURBELL (287-2355) CLICK, GET A QUOTE » CHEMICAL RESISTANCE CHART. 4 Chemicals PVC CPVC PP PVDF ABS. Use this chart to help guide your component selection. Nylon®, Type 6/6 PEEK PET Polycarbonate Polypropylene Polysulfone PPS PVC, Type I PVC, Type II PVDF PTFE Tecator™/Torlon® Interpretation of Chemical Resistance The Chemical Resistance Chart that follows is a general guide only. In the following table, you can see the materials resistance to different chemicals. Buna-N — Satisfactory for Chemical Resistance: Nylon vs. CHEMICAL RESISTANCE CHART RATINGS — CHEMICAL EFFECT A — No effect—Excellent B — Minor effect—Good 2. Nylon is generally chemically resistant to oils and fuels, gasoline, mineral spirits, and some alcohols; Nylon has a high melting point, around 256°C / 492°F; NOT compatible with ozone, most acids; Nylon Chemical Compatibility Chart: Check the chemical compatibility of Nylon with various chemicals, solvents, alcohols and other products. curbellplastics. High chemical resistance CHEMICAL RESISTANCE CHART. However, since the resistance of metals, plastics and elastomers can be affected by highest chemical resistance rating. P. C. Temp. Polypropylene — Satisfactory to 72° F. While polypropylene is highly resistant to many chemicals at room temperatures, its chemical resistance decreases with increased temperatures. V.

Although the chemical resistance of PVC and CPVC compounds is similar, they are not always the same. 1 - High Resistance 2 - Limited Resistance 3 - No Resistance . CURBELL (287-2355) CLICK, GET A QUOTE » Among many of the positive attributes of polypropylene, it is probably best known for its resistance to highly aggressive chemicals. *Important note: Stress cracking is caused by a combination of a stress cracking chemical • Morphology Features -- Excellent Chemical Resistance, Excellent Abrasion Resistance, Good Flow in Thin Mold Sections, Poor Dimensions – PP -- Low Density, Better Thermal Resistance Than PE, Living Hinge Capable, Brittle @ Low Temperatures, Low Cost – HDPE -- Good Low Temp Impact Performance (Tg = -770C vs -90C for PP), Low Cost. 888. The special PVC “A” compound used in Chemline valves resists attack of most acids, strong alkalais, salts and many other chemicals. 4. * www. — Satisfactory to 72° F.
