Polyamide 6 chips, commonly known as nylon 6 chips, nylon 6 chips. Because macromolecules containing amide bond (a CO-NH), the so called polyamides. Nylon 6 chips usually white cylindrical granular, melting point 210-220 ℃, decomposition temperature is about 300 ℃. Soluble phenol and hot concentrated sulfuric acid, excellent electrical insulation properties, alkali, good corrosion resistance. Nylon is a synthetic fiber in the best wear resistance. Nylon chips should be stored in a cool dry place, avoid sunlight, rain, moisture, transport packaging is not damaged.
