CHEMICAL COMPATIBILITY CHART NYLON

1 CHEMICAL COMPATIBILITY CHART NYLON Our products can be exposed to a huge variety of chemicals. The data table below is an application guide , and indicates the resistance of the specific thermoplastics we use in the construction of our products, to common chemicals. The data given should be used cautiously, and as a guide only. Various factors such as concentration, additives, exposure time, temperature and internal mechanical stress levels will all impact on the working life of our plastic parts. Use the table conservatively and if any doubt exists, do not proceed with the application. In the table below there are four ratings: A- Excellent indicates that at ambient temperature and pressure, the material should not be affected.

2 B- Good indicates that the material is slightly affected but not to the point of being unsuitable. C- Fair indicates a degree of reaction that is generally considered unsuitable and should not be used. D- Severe Effect indicates that the material should not be used under any circumstances All ratings are taken from data measured at ambient temperature and pressure.
