Product Introduction

XPS foam sandwich panels are one of the most popular foam sandwich composite panels, which is a typical representative material combining strength and lightweight. Its core material is closed-cell extruded polystyrene foam, and its skin material has a variety of options (fiberglass, aluminum, wood, steel, etc.). The skin and core are bonded together by vacuum compression molding using high-quality polyurethane glue as an adhesive.

XPS Foam Board

XPS (extruded polystyrene), is made of polystyrene resin as raw material plus other auxiliary materials and polymers, while heating and injecting a catalyst, and then extruded to form a rigid foam plastic board. It has a very low Hygroscopicity (almost no water absorption), low thermal conductivity, and high compression resistance. Its surface is uniform and flat, and the interior is a completely closed cell, so it has the characteristics of high-pressure resistance, lightweight, non-absorbent, airtight, wear-resistant, and non-degradable.

Physical Properties of XPS Foam Board

XPS Sandwich Panels are Available in Different Skin at TOPOLO

Because of the good compatibility between XPS foam and glue system, XPS foam can basically be well combined with existing skin materials without delamination. The commonly used skin materials are FRP sheet, aluminum sheets, plywood, stainless steel sheet, aluzinc sheet, etc.

FRP Skin XPS Foam Sandwich Panels

FRP sheet is a composite containing resin and fiberglass, which has the advantages of high strength, rigidity, lightweight, corrosion resistance, waterproof, and electrical insulation. FRP skin XPS foam core sandwich panels have become the material of choice for many camper and box truck builders. Compared with metal or wood-skinned foam sandwich composite panels, its comprehensive performance advantages are obvious.

☑ Lightweight: FRP is lighter compared to metal materials.
☑ Strong: FRP is much stronger than plywood.
☑ Moisture-proof: FRP won’t rot like plywood in wet weather and won’t rust like steel.
☑ Insulation: FRP is a good insulating material.

What Types of FRP Sheets Does TOPOLO Supply?

TOPOLO supplies FRP sheets for XPS foam sandwich panels in two materials with different resin systems: thermoset FRP sheets and thermoplastic CFRT sheets.

Aluminum Skin XPS Foam Sandwich Panels

The aluminum sheet coating we provide is a high-performance fluorocarbon coating (PTFE, PVDF, FEVE), which can prevent the aluminum sheet from being corroded in harsh weather conditions. The advantage of aluminum sheet is that it is the lightest metal, it will not rust and it is completely recyclable. However, the thinner aluminum plate will be deformed or even cracked after being subjected to a large impact force, which is difficult to repair and affects the appearance very much, so aluminum sheets are usually used as the skin on the inner side. The skin on the other side is made of fiberglass. Usually one side of the aluminum skin is sandwiched with fiberglass or plywood as reinforcement.

Plywood Skin XPS Foam Sandwich Panels

Because plywood is easy to absorb water and moisture, but it is particularly strong and easy to cut and process, it is especially suitable for indoor furniture materials. Usually the two sides of the xps sandwich panel will not use plywood completely, but use it as one side of the sandwich panel, or laminate it with FRP or aluminum as one side.

Applications of XPS Foam Sandwich Panels

• XPS sandwich panels are the most popular RV body panels. Such as wall panels, floors, and roof panels for caravans, travel trailers, campers, mobile villas, etc.

• It is suitable for storage and transportation of medicines, fresh meat, vegetables, cold drinks, fruits, etc. It is one of the most important materials for refrigerated truck bodies and cold rooms.

• XPS sandwich panels are widely used in buildings that require heat insulation, such as temporary houses, mobile villas, mobile toilets, etc., which greatly reduce the cost of building construction.

• XPS sandwich panels can be used as wall panels, weather panels, floors, partitions, etc. inside yachts.
