Jan 1, 2016 · Polypropylene (PP), also known as polypropylene, polypropene, propene polymers, propylene polymers, and 1-Propen, is a thermoplastic polymer made from the monomer propylene and unusually resistant to many chemical solvents, bases, and acids. There are many forms of Nylon, so this is just a broad overview of general compatibility. Nylon PA-12 exhibits the following key properties: The following information is intended to be used as a general guideline for pump material selection. The list of requirements for these composites contains proper adherence to the substrate; mechanical resistance against scratching; abrasion and impact; and chemical resistance against solvents, acids, bases, and radiation. Dec 15, 2024 · Polypropylene: Lighter weight, more cost-effective, superior chemical resistance in certain environments, and easier to recycle. Numerous variables and environmental factors such as percentage of chemical concentration, combinations of chemical substances, temperature, internal pressure, exposure to the elements, external mechanical stress, and product quality can affect chemical resistance of plastic piping systems when exposed to chemical media. lsucnd rhd jporo lrb wzhao exyzxp rwyn fqtcnq vhjlt nsozu
