New opportunities for the cost-efficient production of films, containers, and molded parts
From Supersoft to Low Warpage
Polypropylene Blends. With recently introduced PP blends, made by LyondellBasell’s proprietary Catalloy technology and combining the advantages of polyolefines with those of elastomers, Ultrapolymers Deutschland can now offer its customers new opportunities for the cost-efficient production of films, containers, and molded parts. The range of these blends covers three soft grades, Softell 7413 XEP, Softell CA 7469 A and Adflex 7492 XCP, with Shore A values up to 75, characterized by their soft touch, low gloss and high-level mechanical properties, plus Hifax CA 7378 A, a specially modified low density, low warpage copolymer, well suited to injection molded parts for highly demanding applications.
Softell 7413 XEP is a development grade featuring flexibility and toughness on a level commonly only reached by plastomers or traditional elastomers. Thanks to its high flow (MFR = 2.8 g/10 min at 230°C/2.16 kg), typical applications include extruded profiles, sheets and cable coatings as well as calendered, extrusion blow molded and injection molded products with low hardness (Shore A 76), high toughness and high environmental stress crack resistance (ESCR).
Softell CA 7469 A combines softness (Shore A 86), flexibility, low temperature toughness, low gloss, and dry touch characteristics. Used as a cost-efficient and lightweight soft building block in TPE and TPV compounds, this material opens up possibilities to substitute more expensive thermoplastic elastomers like SEBS, depending on the specific requirements.
Adflex 7492 XCP has been developed to produce highly transparent blown film products, which provide toughness, puncture and tear resistance on a metallocene PE-LLD level, clearly outperforming common PP-based blown film products. The material is also well suited for the modification of PE-LD und PE-LLD.
Hifax CA 7378 A is a tough injection molding grade, providing very low shrinkage of only 0.9 % combined with high stiffness and easy processing. This makes this heterophasic PP copolymer a first choice for demanding applications, e. g. for automotive interior and exterior components like dashboards or bumpers, where high dimensional stability is crucial. Compared to products commonly used for such applications like talcum filled PP (with a density > 0.9 g/cm3 ) Hifax CA 7378 A can allow a significant weight reduction without compromising stiffness and impact resistance.
