“It is designed to generate a high-quality surface during the production of FRP components. It is highly suitable for pultrusion, filament winding, RTM, vacuum infusion, and hand lay-up processes.”

Pultrusion is a dynamic process whereby the reinforcement, having passed through a resin bath, is pulled through a heated die to produce a composite component of constant profile. As the process is dynamic, the inclusion of a surfacing veil is the optimum method used to impart a wide range of properties to the surface of the pultruded profile.

A surface veil is a vital component in a pultruded profile. Pultrusion is a dynamic process whereby the reinforcement, having passed through a resin bath, is pulled through.

Correct selection of a surfacing veil can bring the following benefits to a pultruded component:

Surface conductivity.
High-quality surface finish.
Improved corrosion resistance.
Improved wear and impact resistance.
Reduced reinforcement print through.
Elimination of surface penetration of reinforcing fibers.
Improved resistance to UV discoloration and degradation.

In addition to the enhanced properties of the pultruded profile, a synthetic surfacing veil such as those manufactured by Dymriton Industries also improves the pultrusion process itself giving.

Reduced die wear.
Increased line speeds.
Reduced pulling forces.

It absorbs excess resin, which is pressed into the hole when the laminate is sucked in. It can be used in one or more layers. It ensures smooth airflow and good plasticity.

The suction film is made of high-quality Polyester(PES) fiber without adhesive. Due to the uniform and transparent design, the vacuum is evenly distributed over the whole width of the component.

The result: the polyester surface veil is the ideal candidate for delivering lightweight, cost-effective surface engineering solutions for composite applications.
