Direct-Roving-For-Long-Fibre-Thermoplastics
Direct Roving is an alkali-free continuous single-strand direct roving, the surface is coated with silane-based sizing agent. It is suitable for reinforcing unsaturated polyester resin, vinyl resin, epoxy resin and polyurethane resin. It can be used for weaving, filament winding, pultrusion, thermoplastics, wind blades application process.

Applications
Direct Roving For Long Fibre Thermoplastics (LFT) is coated with a silane-based sizing compatible with PA, PBT, PET, PP, ABS, PPS and POM resins. It is designed for G-LFT and D-LFT processes. Its superior compatibility with matrix resin makes it favored in automotive, electrical & electronic, telecommunications, construction, and sports industries etc.
a) G-LFT Process: The thermoplastic polymer is heated to a molten phase and pumped into the die-head The continuous roving is pulled through a dispersion died to ensure the glass fiber and polymer impregrated fully and to get consolidated rods . After cooling,The rod is chopped into reinforced pellets.
b) D-LFT process, Polymer pellets and glass roving are all introduced into atwin - screw extruder where the polymer is melted and compoundis formed . Then the molten compound is directly molded into the final parts by injection or compression molding process.
Typical automotive components made of LFT composites

Storage
The fiberglass products should be stored away from heat and moisture, and in their original packaging. The best conditions are: temperatures between -10 ºC and 35 ºC; humidity between 35 and 65 %. If the product is not stored under these specifications, it is advisable to condition it in the workshop for at least 24 hours before use, to prevent condensation.
To ensure safety and avoid damage to the product, the pallets should be stacked not more than three layers high. When the pallets are stacked in two or three layers, special care should be taken to correctly and smoothly move the upper pallet.
