Adflex Q 300 F TPO – Catalloy Soft Film and PP Toughening Grade

Soft film extrusion often forces a compromise between low density and sufficient stiffness, while impact modification trials with conventional elastomers can consume weeks of compounding time before a stable dispersion is reached. Adflex Q 300 F is a thermoplastic polyolefin produced via LyondellBasell’s Catalloy multi-reactor process, with a nominal density of 0.88 g/cm³. In our experience supplying this grade to film processors and compounders, its value lies in removing that compromise: the propylene-based Catalloy structure disperses readily in PP homopolymer and processes on existing PP extrusion, PVC calendering, and LDPE/LLDPE blown film lines without major equipment changes.

One observation worth flagging for low-temperature applications: notched Charpy impact is higher at −20 °C (100 kJ/m²) than at 23 °C (70 kJ/m²). This inversion is characteristic of the Catalloy multiphase morphology and has practical relevance for cold-chain packaging and winter-exposure film.

Key Properties

Low-density flexibility with dimensional stability. At 0.88 g/cm³ and Shore D 36, Adflex Q 300 F TPO delivers a soft, slightly velvety surface without sacrificing the stiffness needed to hold a bottle or tube shape. A cosmetics packaging converter we work with replaced part of a conventional elastomer in a tube outer layer and reported a visible improvement in surface hand-feel while maintaining sufficient rigidity for filling-line handling.

Dispersion efficiency in PP homopolymer toughening. When used as an impact modifier for PP homopolymer in extrusion, the propylene-based Catalloy chain segments promote interfacial compatibility with the PP matrix. A strapping manufacturer incorporating this grade reported reduced fibrillation at high draw ratios, effectively widening the drawing process window.

Processing versatility across lines. The grade runs on conventional PP extrusion equipment, PVC calenders, and standard LDPE/LLDPE blown film lines. Processors switching from other TPO or POE grades typically do not need to reconfigure screw profiles or overhaul temperature curves.

Food-contact compliance foundation. The base resin meets FDA 21 CFR 177.1520(a)(3)(iii) and (c)3.4 for olefin polymers, and complies with EU 1935/2004/EC framework requirements and EU 10/2011/EC for plastic food-contact materials at the intermediate-material stage. Finished-article migration testing remains the responsibility of the converter.

Applications

Soft-touch protective film. A film processor formulating surface-protection film for PE or PP substrates used Adflex Q 300 F to tune peel force and flexibility. The low flexural modulus helps reduce adhesive residue during lamination, and the film remains flat through winding and unwinding.

Soft-touch consumer bottle and tube surfaces. A packaging converter blended this grade with PP for cosmetics bottle outer layers. The matte, fine-textured surface improved grip, while the polyolefin compatibility of the Adflex Q 300 F TPO grade minimized the risk of interfacial delamination between the outer layer and the structural layer.

PP strapping and heavy-duty packaging film. In strapping extrusion, the grade’s documented effect on fibrillation at high draw ratios is the primary draw. In heavy-duty film, the 550% tensile strain at break provides formulators with room to balance dart impact and puncture resistance.

Technical Comparison: Catalloy TPO vs. Metallocene POE

Dimension	Adflex Q 300 F (Catalloy TPO)	Typical Metallocene POE
Polymerization	Multi-reactor Catalloy, propylene-based multiphase	Metallocene-catalyzed ethylene/α-olefin copolymer
Density range	0.88 g/cm³	Typically 0.86–0.90 g/cm³
Compatibility with PP	Propylene-based segments favor interfacial bonding with PP	Interfacial tension with PP may require compatibilizer in some formulations
Processing line fit	PP extrusion, PVC calendering, LDPE/LLDPE blown film	Primarily PE processing lines

This is not a ranking. The propylene-based Catalloy architecture of Adflex Q 300 F TPO typically offers more direct compatibility in PP toughening and PP/TPO blends. Metallocene POE retains its place in pure PE systems or where an exceptionally low glass transition temperature is required. Grade selection should be driven by the base resin and the available processing line, not by the broad “metallocene” label alone.

Frequently Asked Questions

Q: How does Adflex Q 300 F differ from a metallocene POE in PP toughening?

A: If the matrix is PP homopolymer or copolymer and the goal is to reduce compatibilizer loading while running on an existing PP extrusion line, the propylene-based Catalloy structure of Adflex Q 300 F typically disperses more directly. If the system is predominantly PE, or if the formulation requires an exceptionally low density for maximum softness, a metallocene POE may be the more natural starting point. A side-by-side trial at the target impact level is the most reliable way to decide.

Q: What food-contact documentation is available?

A: The base resin meets FDA 21 CFR 177.1520 and EU 10/2011/EC requirements at the intermediate-material stage. Compliance of the finished article, including overall and specific migration testing, remains the converter’s responsibility. Product Stewardship Bulletin documentation is available to support regulatory review.

Q: Can Adflex Q 300 F run on a standard LDPE blown film line?

A: Yes, it can be processed on standard LDPE/LLDPE film lines. Because the melt flow rate is 0.8 g/10 min, melt viscosity differs from conventional LDPE. We recommend starting with a lower extrusion temperature profile, observing bubble stability and draw ratio, and adjusting gradually rather than transferring an existing LDPE recipe without modification.

Q: Are samples available, and how is the sample cost handled?

A: Samples are fee-based, with the sample cost credited toward the first full order.

Q: What trade modes can support a trial order?

A: General trade and processing trade under manual are both supported, and bonded transit can be arranged for qualified buyers. The appropriate mode depends on the buyer’s customs registration and the intended end use. Specific documentation requirements can be confirmed at the inquiry stage.

Conclusion
