LG Chem LC175 Impact Modifier – Frequently Asked Questions (FAQ)

Q1: What is the primary polymer matrix compatibility of LC175?

A: LG Chem LC175 is specifically engineered for compatibility with rigid PVC (uPVC) and other chlorine-containing thermoplastics, where it enhances impact resistance without significantly compromising stiffness or thermal stability.

Q2: How does LC175 affect processing behavior during extrusion or injection molding?

A: LC175 demonstrates good melt flow characteristics and thermal stability under standard PVC processing conditions. It typically supports smooth extrusion and consistent dispersion without causing die buildup or excessive torque variation when properly compounded.

Q3: Is LC175 suitable for applications requiring long-term weathering resistance?

A: Yes — LC175 contributes to improved retention of mechanical properties after exposure to UV radiation and thermal cycling, particularly in outdoor uPVC profiles and siding, when used in conjunction with appropriate stabilizer systems.

Q4: What is the typical dosage range for LC175 in rigid PVC formulations?

A: LC175 is typically used at low concentrations, generally ranging from 0.1% to 2% by weight relative to the base PVC resin, depending on the target impact performance, end-use requirements, and overall formulation balance.

Q5: Does LC175 require pre-drying before compounding?

A: LC175 is supplied in a dry, free-flowing granular form and does not require pre-drying under normal ambient storage conditions; however, extended exposure to high humidity should be avoided to maintain optimal handling and dispersion performance.
