ALITA 228 – Orthophthalic Pultrusion Resin

ALITA 228 resin boasts high mechanical strength and toughness, making it ideal for pultrusion processes. This resin is particularly suited for manufacturing pultruded fiberglass rods used in tent poles, grilles, doors, windows, and other products.

ALITA 210 – Orthophthalic Pultrusion Resin

ALITA 210 resin stands out with its low viscosity, excellent wetting, and fast curing. Pultruded fiberglass products created with this resin demonstrate good mechanical strength and high elongation, showcasing strong versatility. This resin is particularly suitable for pultrusion molding to manufacture high-quality pultruded fiberglass products.

ALITA 239 – Isophthalic Pultrusion Resin

ALITA 239 resin products offer high mechanical strength, good chemical resistance, and low sensitivity to fractures, resulting in a long fatigue life. With excellent heat resistance, this resin is perfectly suited for pultrusion molding processes, making it an ideal choice for producing high-quality pultruded grilles and other pultruded composite materials.

ALITA 262 – Orthophthalic Pultrusion Resin

ALITA 262 resin offers exceptional rigidity and minimal deformation, making it ideal for the pultrusion process. This resin is perfect for producing pultruded fiberglass products, with a particular emphasis on pultruded grilles, as well as fishing rods and tent poles, through continuous pultrusion. Its superior properties ensure high-performance pultruded composites suitable for various demanding applications.

ALITA 901-1 – Vinyl Ester Pultrusion Resin

ALITA 901-1 is a high-performance epoxy vinyl ester resin specifically designed for fast pultrusion applications, especially for manufacturing high-quality FRP optical cable strength members and FRP rods with diameters from 0.5 mm to 4 mm.

ALITA 7016 – Orthophthalic Pultrusion Resin

ALITA 7016 is an unsaturated polyester resin primarily made from phthalic anhydride, specifically engineered for the demanding requirements of pultrusion molding. Its moderate viscosity and high reactivity make it ideal for manufacturing high-quality pultruded products.

01

Resin Impregnation

Fiber bundles pass through a resin impregnator or wet out device, completely saturating with resin.

02

Preforming

Impregnated fiber bundles pass through “preformer” tools to squeeze out excess resin and align fibers into the desired shape.

03

Steel Die Polymerization

Impregnated fibers pass through a heated steel die where the resin cures and solidifies into a hardened polymer.
