Mitsui TAFMER DF810 Impact Modifier – Frequently Asked Questions (FAQ)

Q1: What is the primary function of TAFMER DF810 in polymer formulations?

A: TAFMER DF810 is an ethylene–α-olefin copolymer impact modifier designed to enhance toughness and low-temperature impact resistance in rigid polypropylene (PP) and polyethylene (PE)-based systems, particularly in injection-molded and extruded applications where improved ductility and crack propagation resistance are required.

Q2: Is TAFMER DF810 compatible with polypropylene homopolymers and copolymers?

A: Yes — TAFMER DF810 exhibits excellent compatibility with both PP homopolymers and random copolymers due to its ethylene–propylene backbone structure, enabling uniform dispersion and strong interfacial adhesion without requiring compatibilizers in most standard formulations.

Q3: How does processing temperature affect the performance of TAFMER DF810 during compounding?

A: TAFMER DF810 has a relatively low melting point and good melt flow characteristics, allowing for efficient dispersion at typical PP compounding temperatures (180–220 °C). Excessive residence time or temperatures above 240 °C should be avoided to prevent thermal degradation and maintain optimal impact enhancement.

Q4: Can TAFMER DF810 be used in food-contact applications?

A: TAFMER DF810 is manufactured using processes and raw materials suitable for indirect food-contact applications in certain jurisdictions; however, final regulatory compliance depends on the complete formulation, processing conditions, and end-use requirements. Users must conduct their own evaluation and obtain appropriate regulatory confirmation prior to use.

Q5: What is the typical dosage range for TAFMER DF810 in PP impact modification?

A: Dosage is formulation-dependent, but TAFMER DF810 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — to achieve noticeable improvements in notched Izod impact strength and flexibility without significantly compromising stiffness or heat deflection temperature.
