XPS core Sandwich panels manufacturer in china
XPS foam sandwich panels are popular insulation materials called ‘XPS insulation boards’. Good thermal and acoustic insulation is frequently used in refrigerated trucks and RVs. It has an XPS (closed cell extruded polystyrene) core. The outside is bonded with FRP, plywood, or CFRT. The XPS foam is a great thermal insulator. It does not absorb water, so it has a long service life. The skin makes XPS panels perform better. The FRP skin can replace traditional materials, like aluminum and steel, to make them stronger. It’s the best choice for refrigerated trucks and RV panels.
We are the most professional XPS sandwich panel manufacturer in China. We offer OEM production with customized sizes and skins, CNC machining services.
Product Description:
XPS sandwich panels are high-performance and very durable, and they offer many advantages. The best advantage is its excellent thermal and sound insulation.
- Good thermal insulation and heat preservation performance.
- High strength: bonded skin to form a high-strength sandwich panel
- Durable: not easy to corrode or age
- Strong: not easy to deform and compress
- Insulation prevents air from entering and exiting.
- Non-absorbent: a closed-cell structure prevents water absorption.
- Chemically stable and designed for a long service life.
customization:
- Surface skin: FRP skin, CFRT, aluminium sheet, plywood, etc.
- Size: length ≤12m, width ≤3.2m, thickness: 20mm~120mm.
- Density: 25~45kg/m³
- Colour customization: yellow, green, blue.
- Skin colour: according to the type of masking
- Compressive strength: tuning density and proportion of foaming agent
Product Structure:
XPS foam board
XPS foam board is also called extruded polystyrene board, it is a kind of rigid closed-cell foam, which has obvious difference with expanded polystyrene, it has less than 1% moisture absorption. Low thermal conductivity. Good impact resistance.

Fiberglass Reinforced Plate
Fiberglass reinforced plate is made by combining glass fibers and resin matrix. It is suitable for the manufacture of fiberglass XPS foam board, which is a high-performance composite material.
