Q1: What is the primary function of LG Chem POE LC670 in polymer formulations?
A: LG Chem POE LC670 is an ethylene-octene copolymer elastomer designed to enhance impact resistance, flexibility, and melt processability—particularly in polyolefin-based systems such as PP and PE blends. It functions as a toughening agent and compatibilizer without significantly compromising stiffness or thermal stability.
Q2: Is POE LC670 suitable for food-contact applications?
A: LG Chem POE LC670 is manufactured under strict quality control and is commonly selected for food-contact compliant formulations when compounded with approved base resins and additives. Final regulatory compliance depends on the complete formulation, processing conditions, and applicable regional requirements—not the POE alone.
Q3: How does LC670 compare to conventional EPR or EPDM impact modifiers?
A: Unlike traditional diene-based elastomers, LC670 offers superior dispersion in polyolefins due to its saturated backbone and narrow molecular weight distribution. This results in improved long-term thermal and UV stability, reduced odor/volatiles, and more consistent mechanical performance in demanding applications like automotive interior parts.
Q4: What are typical processing recommendations for LC670?
A: LC670 processes readily using standard polyolefin equipment—including twin-screw extruders and injection molding machines. It exhibits good thermal stability up to typical processing temperatures (e.g., 180–230 °C), low die swell, and minimal plate-out tendency. Drying is generally not required unless exposed to prolonged high-humidity environments prior to processing.
