NEGA offers the following roving products.


2500H103/DB - 5000H103/DB

For GFRC spray-up applications. The high integrity strand has excellent combination for stiffness for good lay-down and wet-out but is sufficiently soft to allow easy roll-out into corners and other mold details.

2500H350Y/DB - 5000H350Y/DB

Specialty roving, particularly designed for GFRC spray-up of primarily flat products. It is not usually suitable for spray-up of products with shape and molded features due to its high number of strands.

5000H530X/DB

Designed for chopping into chopped strands that are suitable for premix applications. Especially suitable for direct chopping into mixer. The strands obtained from this roving are too stiff for spray-up applications.

Polyplex Acrylic Polymer
