Basell is launching a new high performance range of developmental polypropylene resins called Stretchene which can address the highly specialised customer requirements of injection stretch blow moulding applications (ISBM).
The new family of resins features products that can outperform standard polypropylene in terms of rigidity, transparency, impact strength and production output. These resins' properties and performance attributes address typical customer requirements for a wide range of ISBM applications used in food and household chemical packaging as well as hot-fill applications - historically the domain of traditional materials such as PET or glass.
" The new grade's low density, (0.9 g/cm3) offers a significant weight reduction over traditional materials such as glass and PET. The resin can also outperform conventional polypropylene in terms of rigidity, which enables very high topload potential without distortion. In addition, the material's heat deflection temperature of 1090 C makes this polypropylene a competitive alternative to PET in hot-fill applications.
" Bassel also offers a grade that surpasses standard polypropylene in terms of clarity and provides very high transparency that is required for customer applications such as cosmetic packaging, historically the domain of HDPE-EBM and PET.
