Mitsui TAFMER DF7350 Impact Modifier – Frequently Asked Questions (FAQ)

Q1: What is the primary polymer matrix compatibility of TAFMER DF7350?

A: TAFMER DF7350 is specifically designed for compatibility with polypropylene (PP) homopolymers and copolymers, where it enhances low-temperature impact resistance without significantly compromising stiffness or processability.

Q2: How does DF7350 differ from other TAFMER grades used in PP modification?

A: DF7350 features a tailored ethylene–alpha-olefin copolymer structure optimized for balanced toughness and melt flow in injection-molded PP applications, offering finer dispersion and improved interfacial adhesion compared to higher-melt-index or more elastomeric TAFMER variants.

Q3: What processing methods is DF7350 best suited for?

A: DF7350 is widely used in conventional PP processing techniques including injection molding and extrusion—particularly for thin-walled or structurally demanding parts requiring consistent impact performance across variable wall thicknesses and cooling rates.

Q4: Is DF7350 suitable for food-contact applications?

A: TAFMER DF7350 is manufactured under strict quality control and is commonly incorporated into food-contact PP formulations; however, final regulatory compliance depends on the complete formulation, processing conditions, and applicable regional requirements—users must conduct full migration and safety assessments as part of their own regulatory submission.

Q5: What is the typical dosage range for optimal impact improvement in PP?

A: DF7350 is typically used at low concentrations, generally ranging from 0.1% to 2% by weight in PP, depending on the base resin’s crystallinity, target impact performance, and end-use mechanical balance requirements.
