Emulsion-Bound Fiberglass Chopped Strand Mat

A reinforcement material may have the required strength on paper, but production becomes more difficult when the surface contains curves, corners or changing contours. This is where a Yuruis Emulsion-Bound Fiberglass Chopped Strand Mat becomes useful.

The randomly distributed glass fibers do not create a fixed warp-and-weft direction. Combined with the soft mat structure, this allows the material to be positioned and adjusted over different mold contours during fabrication.

For hand lay-up production in particular, the mat can be cut, placed and layered according to the shape of the finished component.

Specifications

Resin Compatibility for Composite Manufacturing

The mat is compatible with several resin systems used in composite manufacturing:

·  UP Resin  - general-purpose FRP production

·  Vinyl Ester Resin  - corrosion-resistant composite applications

·  Epoxy Resin  - selected higher-performance composite structures

·  PF Resin  - applications using phenolic resin systems

The final performance depends on the complete resin, curing and laminate design rather than the mat alone.

Where Manufacturers Put It to Work

Boat & Marine Products

Useful for curved hulls and other molded sections where reinforcement must follow the contour.

Sanitary Ware

Suitable for bathtubs, shower products and other molded surfaces with complex geometry.

FRP Pipes & Tanks

Can be incorporated into layered composite structures for pipes, tanks and related equipment.

Automotive Components

Used for selected molded composite parts where conformability is important during lay-up.

Cooling Towers & FRP Components

Suitable for fiberglass-reinforced structures produced through established molding processes.

FAQ

1. What does “Emulsion-Bound” mean?

It means the randomly distributed chopped E-Glass fibers are held together using an emulsion-type binder, forming a soft and flexible continuous mat.

2. How is this different from Powder Bound Chopped Strand Mat?

The key difference is the binder system. This product uses an emulsion binder and is positioned around its soft handling and conformability, while powder-bound mat uses a powder binder. The better choice depends on the customer's manufacturing process and required mat behavior.

3. Can it follow curved mold surfaces?

Yes. Its random fiber structure and soft mat form make it suitable for curved surfaces, corners and other molded contours, particularly in hand lay-up applications.

4. Which resins are compatible with the mat?

The listed specification is compatible with unsaturated polyester (UP), vinyl ester (VE), epoxy (EP) and phenolic (PF) resin systems.

5. Can the gram weight and width be customized?

Yes. The reference product is 300 g/m² with a 1.04-meter width. Other specifications can be discussed according to the customer's production requirements.

6. What information should I provide when requesting a quotation?

For a more accurate specification, provide the finished FRP product, molding method, resin system, required gram weight, width, roll length and estimated quantity. For curved or complex products, mold geometry is also useful when evaluating the suitable mat specification.
