Features Of LG Chem EM500 Toughener

  1. Enhances impact resistance and ductility in engineering thermoplastics without compromising heat deflection temperature.

  2. Offers excellent compatibility with polyamide (PA6, PA66) and polyphenylene ether (PPE) blends.

  3. Enables low-temperature toughness retention down to –30 °C for demanding automotive and industrial applications.

  4. Provides consistent dispersion and interfacial adhesion due to optimized reactive functional groups.

  5. Supports high-speed processing via injection molding and extrusion with minimal viscosity increase.

Typical Applications Of LG Chem EM500 Toughener

  1. Automotive under-hood components including intake manifolds and cooling system housings.

  2. Electrical and electronic enclosures requiring UL94 V-0 rated flame-retardant toughened plastics.

  3. Industrial fluid-handling parts such as pump bodies and valve components exposed to thermal cycling.

  4. Consumer appliance structural parts where dimensional stability and drop-impact performance are critical.

  5. Medical device housings requiring biocompatibility-compliant polymer formulations (ISO 10993 compatible when compounded).
