XPS Foam Sandwich Panel

Fiberglass XPS Foam Sandwich Panel

Thermal Insulation | Moisture-proof | Pressure-resistant | Easy to Process
The XPS foam sandwich panel is composed of FRP skin and XPS foam. The XPS foam exhibits excellent insulation performance, effectively preventing heat conduction to achieve insulation and heat preservation. It is also highly durable, capable of withstanding pressures of up to 15-25 psi. The fiberglass reinforced plastic (FRP) skin is made of short glass fibers and thermosetting resin, making it waterproof, moisture-resistant, and smooth-surfaced. The combination of these two materials results in a composite panel that is lightweight yet strong, possessing higher compressive strength than wood fiber and plywood. It is an ideal choice for constructing exterior walls, dry goods trucks, camper vans, and more.

Features & Benefits

Antistatic

Its antistatic properties are improved by adding special antistatic agents.

Flame Retardant

By adding flame retardants to improve its flame retardancy, it is used in areas with high fire safety requirements, such as construction, transportation, etc.

Anti-ultraviolet

Applying special UV protective coatings to the surface of FRP and adding UV antioxidants to the material can help prevent FRP from being damaged by UV rays.

Corrosion Resistance

FRP has strong corrosion resistance in corrosive media such as acids and alkalis, making it an ideal material for use in harsh environments.

Environmental Protection

The fiberglass and resin used in the manufacture of FRP are 100% recyclable. The long life and low maintenance requirements of fiberglass structures also help reduce resource requirements.

High Strength & Lightweight

Despite being lightweight, FRP has high strength and stiffness, allowing it to withstand a wide range of loads and stresses.
