  • What is a non reactive modified polyolefin impact modifier?
  • Atofina introduced a non-reactive modified polyolefin impact modifier, Lotader XX1336, for use in combination with reactive modified polyolefin impact modifiers to improve the impact-flow balance in nylon-6.
  • What elastomers make up the impact modifier market?
  • Elastomers, including EPDM and thermoplastic elastomers, make up about 10% of the market. Chlorinated polyethylenes (CPE) have another 10% share, and other types make up the remainder, says Mr. Gastrock. Styrenic impact modifiers are growing at an AAGR of less than 3%, while other types are growing at rates of 5-6%, he estimates for 2001 to 2006.
  • How do impact modifiers affect a polymer?
  • While impact modifiers by nature reduce the modulus or stiffness of the polymer, various technologies can improve the balance. Mineral fillers are used to increase stiffness, but have traditionally degraded impact resistance.
  • Are impact modifiers and host polymers compatible?
  • In some cases, the impact modifier and host polymer are naturally compatible, as are ethylene-propylene-diene terpolymer (EPDM) impact modifiers in polypropylene (PP). Often, chemical modification is required to compatibilize the two polymers and allow good dispersion and cohesion with the continuous phase.
