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.
