What production processes is the general-purpose direct roving 386H suitable for?

Direct roving 386H is suitable for reinforcing unsaturated polyester resin, vinyl ester resin, and epoxy resin, and can be used in pultrusion, filament winding, weaving, and other application processes.

Are there other types of direct roving?

Yes. We also have the 308H specially designed for reinforcing epoxy resins, mainly used in the production of high-pressure resistant pipes, tanks, and pressure vessels.

What are the standard filament diameters and linear densities?

Our standard filament diameters are 13/17/24um, and the standard linear densities are 300/600/1200/2400/4800/9600 tex.

What certifications do your products have?

We hold ISO 9001 and IATF 16949 quality management system certificates, as well as an energy management system certification.

What are your production and delivery lead times?

If we have stock available, we can ship immediately. If production is required, we can complete production and organise delivery within 3-7 days for 312 series. Please confirm stock, production and delivery time with our sales team.

How are your products packaged?

Our products are packaged on high pallets and low pallets. High pallets hold 48 bobbins, while low pallets hold 36 bobbins. The pallet size is 1.27*0.96m.

What are the shelf life and storage conditions?

Store in a cool, dry place, avoid direct sunlight, keep the original packaging sealed to prevent moisture, and avoid deformation due to heavy pressure.

Is the wet-out speed of direct roving fast?

Yes. High-quality direct roving is optimized in the sizing formula to achieve fast and complete wet-out. This helps shorten the molding cycle and reduce dry fiber and bubble defects in finished parts.

What is the minimum order quantity (MOQ)?

Our minimum order quantity is 1 ton, which is equivalent to one high pallet.

What should I do if there is excessive fuzz during processing?

Fuzz is a common issue in direct roving processing. High-quality products are characterized by low fuzz and good processability. If excessive fuzz occurs, possible causes include improper yarn tension settings, moisture absorption of the roving, or inherent product quality issues.

Can direct roving still be used after absorbing moisture?

Glass fiber has low water absorption, but prolonged moisture exposure will still affect its performance. Recommendations: Keep unused spools sealed in their original packaging; store opened products in a dry environment; severely damp products are recommended to be scrapped or consult your supplier.

How to choose the right direct roving grade?

Consider factors such as the resin system to be reinforced, linear density, molding process, mechanical performance requirements, and filament diameter.

Do you provide batch test reports?

Yes. We provide a batch certificate of analysis for each shipment.

In which high-end fields can direct roving be used?

Aerospace components, wind turbine blades, high-pressure pipes and vessels, optical fiber cable strength members, automotive lightweight components, sports equipment, etc.

Do you offer price or supply guarantees for long-term orders?

Yes. For long-term partners, we will prioritize ensuring supply volume and provide the best possible price support.
