Features Of LG Chem Impact Modifier MB880 Toughener

  1. Highly effective rubber-modified acrylic core–shell structure for balanced impact strength and processability.

  2. Excellent compatibility with polycarbonate (PC), PC/ABS blends, and other engineering thermoplastics.

  3. Maintains high heat deflection temperature (HDT) and dimensional stability after toughening.

  4. Enables low-temperature impact resistance without significant sacrifice in tensile strength or surface gloss.

  5. Designed for stable melt flow during extrusion and injection molding—minimizes die buildup and improves production efficiency.

Typical Applications Of LG Chem Impact Modifier MB880 Toughener

  1. Automotive interior and exterior components requiring crash-resistant, aesthetically consistent parts.

  2. Electrical and electronic housings demanding UL94 V-0 rated flame-retardant PC or PC/ABS systems.

  3. Medical device enclosures where impact resilience, biocompatibility support, and sterilization resistance are critical.

  4. Consumer electronics casings needing scratch resistance, drop performance, and high-gloss finish retention.

  5. Industrial equipment panels exposed to mechanical stress, vibration, and thermal cycling.
