SK Chemicals INFUSE 8705L Impact Modifier – Frequently Asked Questions (FAQ)

Q1: What is the primary polymer matrix compatibility of INFUSE 8705L?

A: INFUSE 8705L is specifically engineered for compatibility with polypropylene (PP) and other polyolefin-based systems, where it enhances low-temperature impact resistance without significantly compromising stiffness or melt processability.

Q2: How does INFUSE 8705L differ from conventional ethylene-propylene rubber (EPR) impact modifiers?

A: Unlike traditional EPR modifiers, INFUSE 8705L is a thermoplastic olefin elastomer (TPO) with controlled molecular architecture, offering improved dispersion in PP matrices, enhanced shear stability during processing, and better retention of mechanical balance between toughness and rigidity.

Q3: What is the typical dosage range for INFUSE 8705L in polypropylene compounds?

A: Dosage depends on the target impact performance and base resin characteristics, but INFUSE 8705L is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—to achieve meaningful improvements in notched Izod impact strength while maintaining acceptable flow and surface quality.

Q4: Can INFUSE 8705L be used in applications requiring regulatory compliance for food contact or medical devices?

A: INFUSE 8705L is designed for industrial and durable goods applications; users intending to employ it in regulated environments such as food-contact or medical devices must conduct full formulation-level compliance assessments, including migration testing and regulatory review, as SK Chemicals does not provide pre-validated regulatory certifications for specific end uses.
