LG Chem LC875 Impact modifier – Frequently Asked Questions (FAQ)

Q1: What is the primary polymer matrix compatibility of LC875?

A: LG Chem LC875 is specifically engineered for use in rigid PVC formulations, where it enhances impact resistance without compromising dimensional stability or processability. It demonstrates good compatibility with standard PVC resins and common stabilizer systems used in extrusion and injection molding applications.

Q2: How does LC875 affect processing behavior during extrusion or calendering?

A: LC875 is designed to maintain favorable melt rheology in PVC compounds, supporting smooth extrusion and reduced die swell. It typically does not significantly increase melt viscosity at recommended dosage levels and contributes to stable torque profiles during compounding and shaping processes.

Q3: Is LC875 suitable for applications requiring weather resistance or long-term outdoor performance?

A: Yes — LC875 contributes to improved retention of impact strength after UV exposure and thermal aging in PVC profiles and siding applications. Its structure supports compatibility with standard UV absorbers and HALS stabilizers commonly used in weatherable PVC compounds.

Q4: What is the typical dosage range for LC875 in rigid PVC formulations?

A: LC875 is typically used at low concentrations, generally ranging from 0.1% to 2% by weight relative to the PVC resin, depending on the target impact performance, final part geometry, and regulatory or performance requirements of the end application.

Q5: Does LC875 require special handling or drying prior to compounding?

A: LC875 is supplied as a free-flowing, dry granular material and does not require pre-drying under standard ambient storage conditions. However, prolonged exposure to high humidity should be avoided to maintain optimal feeding consistency during high-speed compounding.
