LG Chem LC170 Impact Modifier – Frequently Asked Questions (FAQ)

Q1: What is the primary function of LG Chem LC170 in polymer formulations?

A: LG Chem LC170 is a reactive acrylic impact modifier designed to significantly enhance the toughness and low-temperature impact resistance of rigid thermoplastics—particularly PVC, polycarbonate, and certain engineering blends—without compromising clarity or processability.

Q2: How does LC170 differ from conventional MBS or ABS-based impact modifiers?

A: Unlike non-reactive MBS or ABS modifiers, LC170 contains functional groups that enable covalent bonding with the host polymer matrix during processing—leading to improved dispersion stability, reduced bleed-out risk, and superior long-term mechanical retention under thermal or environmental stress.

Q3: Is LC170 suitable for applications requiring optical clarity?

A: Yes—LC170 is specifically engineered for transparent or translucent systems. Its refractive index is closely matched to common clear polymers such as PC and rigid PVC, enabling high transparency retention even at effective impact-enhancing loadings.

Q4: What processing methods are compatible with LC170?

A: LC170 is fully compatible with standard thermoplastic processing techniques including extrusion, injection molding, and compounding. It exhibits excellent thermal stability up to typical processing temperatures for PVC and engineering thermoplastics and requires no special drying or handling precautions.

Q5: How should LC170 be incorporated into a formulation?

A: LC170 is typically introduced during the dry-blend or masterbatch stage prior to melt processing. It disperses readily in common polymer carriers and is generally used at low concentrations; optimal dosage depends on the base resin, desired performance balance, and end-use requirements.
