SK Chemicals 6805 Impact Modifier – Frequently Asked Questions (FAQ)

Q1: What is the primary function of SK Chemicals 6805 in polymer formulations?

A: SK Chemicals 6805 is an acrylic-based impact modifier designed to significantly enhance the toughness and low-temperature impact resistance of rigid thermoplastics—particularly PVC, polycarbonate, and PC/ABS blends—without compromising clarity or processability.

Q2: Is SK Chemicals 6805 suitable for transparent applications?

A: Yes. Its fine particle size distribution and refractive index compatibility with common engineering resins enable excellent optical clarity retention in transparent or translucent end products, making it well-suited for applications such as lighting housings, medical device components, and premium consumer electronics enclosures.

Q3: How is SK Chemicals 6805 typically incorporated into a polymer matrix?

A: It is commonly added during compounding via twin-screw extrusion or dry-blended with base resin prior to injection molding or extrusion. Due to its excellent dispersion characteristics and thermal stability, it integrates efficiently without requiring specialized feeding equipment or pre-treatment.

Q4: Does SK Chemicals 6805 affect the heat deflection temperature (HDT) or dimensional stability of modified polymers?

A: Unlike some rubber-based modifiers, SK Chemicals 6805 generally maintains or only slightly reduces HDT and contributes to good dimensional stability, thanks to its rigid acrylic core structure and strong interfacial adhesion with the host matrix.

Q5: What is the recommended dosage range for optimal performance?

A: Dosage depends on the base polymer, desired impact performance, and processing conditions—but it is typically used at low concentrations, generally ranging from 0.1% to 2% by weight. Optimization is best achieved through small-scale formulation trials.
