High Strength 4800tex Fiberglass Direct Roving for Pultrusion

Product Description

Product Description
→Fiberglass Direct Roving:
Which is coated with a silane-based sizing and compatible with unsaturated resin, vinyl resin, and epoxy resin. It used to produce gratings, various rods and profiles. Main uses include manufacture of FRP pipes of various diameters, high-pressure pipes for petroleum transitions, pressure vessels, storage tanks, and, insulation materials such as utility rods and insulation tube.
It's also called Single-end roving is the primary reinforcement for filament winding and pultrusion applications and is the input fiber used to produce woven roving and knitted fabrics.Single-end continuous rovings are produced by pulling glass fibers directly from the furnace bushing, applying sizing to the cooling fibers, and winding them into a roving package or doff. Because of its excellent dry tensile strength, single-end rovings are ideal for high glass content applications like pultrusion and filament winding. Because the fiber is used as input for woven roving and knitted fabrics, single-end rovings are also widely use in open mold and infusion applications when configured into fabrics.

→Assembled Fiberglass Roving:
Which is compatible with unsaturated polyester resin.It delivers properties of low static,excellent dispersion and good wet out in resins.It is mainly used in bathroom,vessels and etc.
It's also called Gun Roving / Spray up roving which is used in the spray-up (chopping) molding process and is the reinforcement of choice for high production open mold manufacturing.Gun Roving (also known as continuous strand roving) is comprised of many small diameter fiberglass filaments that are combined to form a roving fiber bundle that is wound into a doff or a creel. In the spray-up process, the continuous roving strand is fed into a chopper gun that chops the strands into short lengths and deposits the fiber into a resin spray pattern for application on the mold surface. In this way, the wet-out glass laminate is created from the spray gun. The laminate is then rolled to remove entrapped air and the laminate cures. Gun Roving used in the chopping process provides fast production of larger parts like boat hulls, RV parts, and swimming pools and is the most common reinforcement used in open mold manufacturing.

Storage
Unless otherwise specified, the fiberglass products should be in dry, cool and moisture-proof area. The room temperature and humidity should be always maintained at 15ºC~35ºC and 35%~65%. It is best if the price is used within 12 months after production date. The fiberglass products should remain in their original packaging until just prior to user.
To ensure safety and avoid damage to the product, the pallets not be stacked more than three layers high. When the pallets are stacked in 2 or 3 layers, special care should be taken to correctly and smoothly move the top pallet.
