Family members, many people are curious whether phenolic resin is polyester, but in fact, there is a big difference between them! Phenolic resin is formed by the condensation of phenols (such as phenol) and aldehydes (such as formaldehyde), and has unique heat resistance, flame retardancy, and chemical stability. It is commonly used in fields such as electrical appliances and automobiles. Polyester is formed by the condensation of polyols and polyacids, similar to common polyester fibers (polyester), which are soft and durable, and are commonly used in clothing and home fabrics. The raw materials, structures, and properties of the two are different, and their application scenarios are also varied. Don't confuse them again when you see them again in the future!
