Para-Nonylphenol (PNP) is an intermediate chemical for thermal stabilization for polyvinyl chloride (PVC) and phenolic resins used in inks and coatings. Para-Nonylphenol (also known as 4-nonylphenol) offers various functions, such as an intermediate in a chemical reaction to produce another compound. Para-Nonylphenol produces phenolic resins by chemical reaction with aldehydes. If used with other phenols, 4-Nonlyphenol may create a more beneficial phenolic resin with characteristics such as solubility inside the oil and improved dielectric and hydrophobic properties.
