Features Of Dow EXL-2620 Nylon Flame Retardant

  1. Halogen-free formulation meeting stringent environmental and regulatory requirements.

  2. Excellent thermal stability for processing at high temperatures typical of nylon injection molding.

  3. Maintains high mechanical performance—including tensile strength and impact resistance—after flame-retardant modification.

  4. Low smoke density and reduced toxic gas emission during combustion, supporting UL 94 V-0 rating in thin-wall nylon applications.

  5. Good compatibility with polyamide 6 and polyamide 66 resins without significant degradation of melt flow or long-term hydrolytic stability.

Typical Applications Of Dow EXL-2620 Nylon Flame Retardant

  1. Electrical connectors and housings requiring UL 94 V-0 compliance at 1.5 mm thickness.

  2. Automotive under-hood components exposed to elevated temperatures and flame-risk environments.

  3. Consumer electronics enclosures, including laptop bases and power adapter housings.

  4. Industrial control system parts where electrical insulation and fire safety are critical.

  5. LED lighting fixtures demanding low-smoke, halogen-free flame retardancy.
