Good electrical insulating properties No resistance to UV rays Lightweight; sometimes used in applications in place of metals Excellent fuel and oil resistance Attacked by strong mineral acids and absorbs polar solvents High water absorption; Nylons and UV rays Nylons are not UV resistant, although you can add stabilisers to give them almost any effect you desire. Its properties are determined by the R and R' groups in the monomers. Nylon 6,6 is usually more crystalline and more ordered than Nylon 6 resulting in slightly different physical properties such as higher melting point, higher modulus, and lower moisture absorption, whereas Nylon 6 has somewhat better ductility and impact resistance. They can be used interchangeably for various applications, but there are some property differences to note: Nylon 6: Nylon 6 is usually produced in two forms: for textile use and high-strength types for industrial uses. Extruded Nylon 6/6 tubing available in a variety of colors and sizes. Nylon 6,6 - polyamide; Polystyrene (PS) DNA/RNA Base Pairs; cis-Platin and DNA; Polymers. ; Amorphous density at 25oC: 1.07g/cm3. Nylon is one of the most commonly used engineering thermoplastics. Charles R. Davis. Si un seul numéro est mentionné, cela signifie que le monomère est un aminoacide Alpha (ou son lactame) et que les chaînons amides dans le polymère sont tous "tête à queue".
