When to Use Fiberglass Direct Roving？

Fiberglass direct roving is a continuous strand of glass fibers that are twisted together and wound into a cylindrical package. It is used in applications where a high degree of mechanical strength is required, such as composite materials, automotive components, and wind turbine blades. Additionally, direct roving is ideal for pultrusion, filament winding, and sheet molding compound (SMC).

Fiberglass gun roving , on the other hand, is a chopped strand of glass fibers that are fed through a pneumatic gun to spray onto a surface. It is typically used in applications that require a quick buildup of material, such as boat building, swimming pool manufacturing, and spray-up molding.

When choosing between fiberglass direct roving and fiberglass gun roving , there are several factors to consider:

1. Manufacturing Process: Consider the manufacturing process being used. Direct roving is the ideal choice for manufacturing processes that require high-strength and stiffness, such as pultrusion or filament winding. Whereas, gun roving is better suited for the quick buildup of material on a surface, making it more suited for spray-up molding applications.
2. Technical Requirements: Consider the technical requirements of the product. If you need a product that has a high strength-to-weight ratio, such as wind turbine blades, then direct roving  is the right choice. However, if the product requires a quick buildup of material or a thick coating, such as a swimming pool, then gun roving should be considered.
3. Product Performance: The desired performance of the product also plays a role in the selection of roving. Direct roving can provide higher mechanical strength and stiffness, which is important in applications where the product must withstand heavy loads. Gun roving , on the other hand, provides a higher coverage area, which is ideal for products that require a thick coating.
4. Cost: Finally, consider the cost of the roving. Direct roving is generally more expensive than gun roving, so it’s important to weigh the benefits of both options against the cost. Overall, choosing between fiberglass direct roving and fiberglass gun roving depends on the specific application and its requirements. By understanding the processes, performance, and cost of each material, manufacturers can make an informed decision on which type of roving on which to rely.

Due to its strength, durability and versatility, fiberglass roving has been widely used in many areas such as building construction, corrosion resistance, energy-saving, transportation etc. It is mostly used as a reinforcement for composite materials, offering supplementary strength, stiffness and other functional properties.This article will show you the different types of fiberglass roving available in the market, their properties and applications.

What is the difference between fiberglass direct roving and assembled roving?

Fiberglass Multi-end roving is also called assembled roving. The expression "multi-end" indicates that the fiberglass strand has a specific number of splits or ends. In contrast, a direct roving or single-end roving has only one end - only one full strand.

What is the TEX of fiber?

Tex is a unit of measure for the linear mass density of fibers, yarns and thread and is defined as the mass in grams per meters. For example, fiberglass tex, means the weight of meters fiberglass roving is grams. Fiberglass tex, means the weight of meters fiberglass roving is grams

ECR Fiberglass Roving

ECR Fiberglass direct roving is a type of roving that is produced using an advanced manufacturing process that brings a higher level of fiber alignment and reduced fuzziness. ECR glass fiber, boasts alkali and acid resistance, good heat resistance, low electrical leakage, and superior mechanical strength compared to E-glass. It is also very environmentally friendly and used to create durable, transparent fiberglass-reinforced panels. Its composition comprises materials with alkali and acid resistance, high heat resistance, waterproof properties, and mechanical strength. It is generally used in applications where high strength, stiffness, and dimensional stability are required, such as in the production of wind turbine blades and aerospace components.
