Description

Poly(Propylene-Co-1-Butene) is a high-performance copolymer engineered to combine the desirable properties of polypropylene with enhanced flexibility and impact resistance. This material matters for formulators and compounders seeking to fine-tune the mechanical and thermal characteristics of their polymer products without compromising processability. It is primarily needed by manufacturers in the packaging, automotive, and consumer goods industries for applications requiring durable, yet flexible, plastic components.

Application

• Modification of polypropylene (PP) to improve low-temperature impact strength and flexibility.
• Key component in the production of flexible packaging films and multilayer film structures.
• Used in automotive interior and exterior parts, such as bumpers and trim, for enhanced durability.
• Formulation of hot-melt adhesives and sealants with improved elasticity and adhesion.
• Manufacture of consumer goods like storage containers, housewares, and toys.
• Wire and cable jacketing where a balance of flexibility and environmental stress crack resistance is required.
• As a compatibilizer or impact modifier in polymer blends and composites.
