Efficient SRPP composite manufacturing with Lucofin® X1026-1
The standard manufacturing process for self-reinforced polypropylene (SRPP) composites relies on coextrusion techniques, in which polypropylene tapes with varying melting points are combined. In this setup, tapes with a lower melting point act as the matrix material, melting during processing and bonding the structure together, while tapes with a higher melting point maintain their form and serve as the reinforcing element. This dual-phase design creates a composite that is lightweight, mechanically strong, and fully recyclable due to its mono-material nature.
Lucofin® offers an innovative and simplified solution for SRPP production by replacing traditional coextruded tapes with a specialized bonding film: Lucofin® X1026-1. This film is designed to act as the matrix material, making it possible to directly bond layers of woven polypropylene fabric in a single, three-dimensional lamination step. The Lucofin® film has a lower melting point and flows during processing, ensuring strong adhesion between the fabric layers while preserving the structural integrity of the reinforcement.
This method significantly reduces the complexity of the SRPP manufacturing process. It eliminates the need for prior tape production and the meticulous tape-laying process typically required before compression molding. Instead, manufacturers can achieve durable composite structures through direct processing with fewer steps, saving both time and cost.
Another key benefit of the Lucofin® solution is thermal stability: the resulting composite maintains its performance at elevated temperatures, withstanding long-term exposure to 90–120 °C without compromising mechanical integrity.
With Lucofin® X1026-1, manufacturers gain access to a costeffective, efficient, and robust process for producing SRPP composites, ideally suited for applications in automotive, packaging, sports, and construction– especially where lightweight performance and recyclability are essential.
