Direct Roving
Direct Roving
906 is used in filament winding, pultrusion and weaving applications in polyester resin systems or vinyl resin systems.
906 can be used to manufacture the optical cable reinforced core, pultruded profiles and multi-axial fabrics.
Characteristics
·Good processing characteristics
·Low fuzz
·Good acid-resistant
·Good mechanical and fatigue properties

Application
E-glass Direct Roving is compatible with polyester, vinyl ester, epoxy and phenolic resins etc., this products is extensively used in filament winding, pultrusion processes, also used in weaving fabrics and woven roving.
Storage
The rovings should be stored away from heat and moisture, and in their original packaging. The best conditions
are: temperatures between 15 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.
The pallets can be stored in 2 levels（1/1).
928 Roving is used in filament winding, pultrusion and weaving applications in polyester resin systems or vinyl resin systems.
928 can be used to manufacture the optical cable reinforced core, pultruded profiles and multi-axial fabrics.
