Johns Manville launches multi-end roving MultiStar 272
Multi-end fiberglass roving serves as a reliable product for SMC compounders aiming to excel in automotive applications.
Johns Manville (JM, Denver, Colo., U.S.), a Berkshire Hathaway company, introduces the MultiStar 272 multi-end (assembled) roving to the North American market. Multi-end roving is a fiberglass material in which multiple strands of fiber are bundled together to create a stronger, more versatile product used in composites manufacturing.
MultiStar 272 is designed to meet the automotive industry’s increasing demands for high-performance, lightweight materials with high-quality surface finishes. It is specifically designed to enhance the capabilities of the sheet molding compound (SMC) downstream value chain and is said to enable the achievement of stringent Class A surface quality standards, as required by automotive OEMs for their final products.
Achieving Class A finishes presents many challenges, including the need for optimal raw material balance, efficient processing and minimizing surface imperfections. JM points out that MultiStar 272 addresses these challenges with improved wet-out properties, optimized chopping performance and low fuzz formation, ensuring a smooth and defect-free surface.
“Our extensive experience in Europe has shown that MultiStar 272 ensures the consistency and quality required to achieve Class A finishes,” emphasizes Pat Reinagel, global portfolio manager fiberglass at JM. “We are thrilled to bring this expertise to the North American market.”
