Mitsui TAFMER DF710 Impact Modifier – Frequently Asked Questions (FAQ)

Q1: What is the primary function of TAFMER DF710 in polymer formulations?

A: TAFMER DF710 is an ethylene–α-olefin copolymer-based impact modifier designed to enhance toughness and low-temperature impact resistance in rigid thermoplastic matrices—particularly polypropylene (PP) and polyethylene (PE) compounds—without significantly compromising stiffness or processability.

Q2: Which polymer systems is TAFMER DF710 most commonly blended with?

A: It is widely used in homopolymer and copolymer polypropylene systems—including injection-molded automotive parts, thin-walled packaging, and medical-grade components—as well as in certain HDPE and LLDPE applications where improved ductility and crack resistance are required.

Q3: How does TAFMER DF710 differ from conventional EPDM or EPR impact modifiers?

A: Unlike traditional elastomeric modifiers, TAFMER DF710 offers superior compatibility with polyolefins due to its linear, narrow-molecular-weight-distribution structure and controlled comonomer content, enabling finer dispersion, better interfacial adhesion, and more consistent property enhancement at lower dosage levels.

Q4: Is TAFMER DF710 suitable for applications requiring regulatory compliance for food contact or medical use?

A: TAFMER DF710 is manufactured under strict quality control and is widely utilized in formulations intended for food-contact and medical applications; however, final regulatory approval depends on the complete formulation, processing conditions, and applicable regional requirements—users should conduct appropriate testing and verification for their specific end-use.

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

A: Dosage is formulation-dependent, but TAFMER DF710 is typically effective at low concentrations—generally ranging from 0.1% to 2% by weight—depending on the base resin, desired balance of impact/stiffness, and processing method.
