Key Benefits of This Direct Roving
- Fast wet out across unsaturated polyester, vinyl ester, and epoxy resin systems
- Excellent tensile, flexural, and shear properties for structural profiles
- Three grades covering tex ranges from 300 to 9600 to match different line speeds
- Consistent mechanical performance for high-volume pultrusion production
- Compatible with polyurethane resin systems in the 312T grade
Applications Across Industries
Direct Roving for Pultrusion supports a wide range of end-use applications across several industries:
- Building & construction: structural profiles, sectional bars, and reinforced building components
- Electrical & electronics: insulator rods and electrical-grade pultruded profiles
- Telecommunication: antenna masts and non-conductive support structures
- Automotive parts: structural pultruded components for lightweight assemblies
This range of applications reflects why this roving is specified across both general sectional bar production and high performance pultruded profiles, giving fabricators flexibility to standardize on one roving family across multiple product lines.
Choosing the Right Grade for Your Pultrusion Line
Because Direct Roving for Pultrusion is offered in three grades, matching the correct grade to a specific profile design affects both mechanical performance and processing consistency. Grade 386T covers the widest tex range, from 300 to 9600, making it a flexible choice for general sectional bar production across varying line speeds. Grade 312 offers a narrower tex range with excellent mechanical properties for standard sectional bar applications.
Grade 312T is positioned specifically for high performance pultruded profiles, offering excellent tensile, flexural, and shear properties along with compatibility with polyurethane resin systems in addition to unsaturated polyester, vinyl ester, and epoxy. Fabricators producing profiles with higher structural demands, such as load-bearing sectional bars, typically evaluate 312T against their target mechanical specifications before qualification.
What to Consider When Sourcing This Roving
When sourcing Direct Roving for Pultrusion, fabricators typically evaluate tex availability, resin compatibility, and the mechanical property data needed for their specific profile design. Working with a supplier that can provide consistent documentation and responsive technical support can help reduce qualification time when approving a new roving grade for a pultrusion line.
Buyers switching between grades or suppliers should confirm current wet out performance and mechanical property data for their specific resin system and die design, since pulling speed and die temperature settings may need adjustment when changing roving grade.
Compatibility with Resin Systems and Pultrusion Equipment
Direct Roving for Pultrusion is designed for fast wet out as it passes through the resin bath on a pultrusion line, helping maintain consistent fiber wet-through at production line speeds without starving the profile of resin. Its mechanical property profile is intended to support the tensile and flexural loads that pultruded profiles experience during the pulling and curing process.
On creel and guide systems, consistent tex and roving quality help avoid filament breakage and fuzz buildup at guide eyes, which can otherwise interrupt continuous pulling. Fabricators running high-speed pultrusion lines should confirm current roving specifications and packaging format against their creel capacity and line speed requirements.
General Handling and Storage Guidance
As with most glass fiber roving products, this roving should be kept in its original packaging, stored in a clean, dry location away from moisture and direct sunlight, and used within the manufacturer’s recommended shelf life. Because wet out performance can be affected by humidity and contamination, packages should be resealed promptly after each use.
Shelf life and specific storage recommendations vary by batch and packaging format, so fabricators should always confirm current shelf life, recommended storage conditions, and any handling precautions against the latest technical data sheet and SDS for the specific batch and grade they are working with.
Choosing Between Direct Roving for Pultrusion and Other Glass Fiber Reinforcements
Thousands Chemicals also supplies Woven Roving and Chopped Strand Mat, which are typically combined with continuous roving in a pultruded profile to improve transverse strength and surface finish. While Direct Roving for Pultrusion provides the longitudinal reinforcement that gives a profile its pulling strength, mat or veil layers are often added at the surface to reduce fiber show-through and improve corrosion resistance.
Fabricators designing a new profile cross-section should confirm which combination of roving, mat, and surfacing veil best matches their target mechanical properties and appearance requirements. Our team can help specify a reinforcement package based on your die design and end-use application.
