Product Highlights

General Purpose: Assembled roving is a high-performance reinforcement designed for open molding processes including spray-up, hand lay-up, and centrifugal casting.
High Surface: Assembled roving offers excellent pigmentability and surface finish for high-quality SMC parts such as automotive ceilings and industrial panels.
Transparent Expert: Assembled roving ensures high light transmittance and no white threads, making it ideal for transparent sheets and translucent panels.
Easy Chopping: Assembled roving enables smooth cutting during high-speed spraying without jamming.
Low Static: Assembled roving prevents fibers from flying or clinging to mold edges due to static electricity.
No Rebound: Assembled roving provides excellent mold contact with no rebound even at small angles.
Fast Wet-out: Assembled roving achieves rapid and complete wet-out, which ensures easy roll-out and quick air release, greatly boosting production efficiency.
Strong Bonding: Assembled roving uses a silane-based sizing that ensures perfect chemical bonding with unsaturated polyester, vinyl ester, and polyurethane resins.
Low Moisture: Assembled roving maintains moisture content at <=0.07%, effectively preventing voids, pinholes, and poor wet-out in final parts.
Stable Tex: Assembled roving controls linear density variation strictly within +/-4%, ensuring consistent part weight and reliable product quality.
