ExxonMobil 9361 Impact Modifier – Frequently Asked Questions (FAQ)

Q1: What types of polymers is ExxonMobil 9361 Impact Modifier designed for?

A: ExxonMobil 9361 is specifically engineered for use in rigid polypropylene (PP) and polyethylene (PE) homopolymer and copolymer systems, where enhanced low-temperature impact resistance and improved toughness are required without significantly compromising stiffness or processability.

Q2: How does ExxonMobil 9361 differ from conventional EPDM-based impact modifiers?

A: Unlike traditional EPDM elastomers, ExxonMobil 9361 features a tailored ethylene-propylene-diene terpolymer architecture with optimized molecular weight distribution and compatibility characteristics, enabling finer dispersion in PP matrices and more efficient stress transfer during impact events.

Q3: What is the typical dosage range for ExxonMobil 9361 in polypropylene applications?

A: Dosage depends on the target performance balance, but ExxonMobil 9361 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—in rigid PP formulations to achieve meaningful improvements in notched Izod impact strength while maintaining acceptable flexural modulus.

Q4: Can ExxonMobil 9361 be incorporated using standard compounding equipment?

A: Yes—ExxonMobil 9361 is supplied as free-flowing pellets and is compatible with conventional twin-screw extrusion and high-speed mixing processes commonly used for PP compound preparation. It exhibits good thermal stability under typical processing conditions and requires no special handling beyond standard polymer additive practices.

Q5: Does ExxonMobil 9361 affect the clarity or surface finish of finished parts?

A: In most rigid PP applications, ExxonMobil 9361 has minimal effect on surface gloss and does not induce significant haze when properly dispersed. However, transparency-sensitive applications (e.g., thin-walled transparent containers) may require evaluation, as phase morphology can influence optical properties depending on formulation and processing.
