Single End Roving
Singleend rovings are specially designed as reinforcements for thermoset resins used in filament winding and pultrusion processes, hand lay-up and woven roving products. The end products are filament wound pipes, pressure vessels, structural shapes, boats, and chemical storage tanks, etc..
The size systems of single end rovings are made to achieve good wetting characteristics and compatibility with polyester,vinylester and epoxy resins.
Properties
¡¤ Good strand integrity
¡¤ Fast and complete wet-out
¡¤ Good humidity resistance
¡¤ No fuzz
¡¤ Excellent mechanical properties |

Spray Up Roving
Spray up rovings are specially designed to achieve excellent performance for spray up molding of fiberglass reinforced thermoset plastic products such as boat shells, tub-shower units,storage tanks,pipes,automotive parts and colling towers,etc..
The spray up rovings, treated with silane-based size , are made to achieve good compatibility with various resins.
Properties
¡¤ Easy chopping
¡¤ Good dispersion and flatlay-down on the mold
¡¤ Good wetting characteristics
¡¤ Easy roll-out and air release
¡¤ Low static
¡¤ Excellent mechanical properties
