What’s fiberglass PET foam panels？

Fiberglass PET foam panels are a new type of environmentally friendly composite material; the PET core’s recyclability helps reduce pollution in the environment. The colors are white or green. It is a high-strength composite material that can be used for wall panels, flooring, and partition walls with excellent load-bearing capacity.
Composite Box is the best FRP PET sandwich panel manufacturer; we support OEM customization, CNC machining, embedded reinforcement, and so on.

Materials that are green, recyclable, and friendly to the environment
High-performance FRP + lightweight PET foam
High-strength and durable.
Scale production at an affordable price.

Product Description:

Structure: FRP sheet for the skin, PET foam core for the core.

Composite-box manufacturer has been specializing in the production of fiberglass PET foam panels for 20 years. PET is a recyclable and environmentally friendly foam core. Interestingly, the recycled PET foam core is green in color. Our diverse range of products is sure to be ideal for you.

Our products are bonded using environmentally friendly adhesives and laminated using vacuum and high-pressure equipment. This ensures that they will not crack and de-glue during use. If you need to use them for special applications or high-strength scenarios, they can be embedded with reinforced steel, FRP, aluminum profiles, plywood, etc. to be more robust. Our products have a long service life, and the exterior treatment uses a film that protects the FRP skin, and the exterior can also be added with flame retardant and anti-UV agents to improve durability. The working temperature can reach -40℃ to 130℃.

Product Advantage:

High-performance, durable, impact resistance.
Chemical-resistant, waterproof, and moistureproof.
Waterproof; not easy to deform.
CNC is easy to process and easy to install.
Recyclable and very environmentally friendly.
More stable than XPS and PU.

Structure of fiberglass PET foam sandwich panels

PET foam

PET foam is a thermoplastic core material with a density of 80~200KG/m³, a recyclable lightweight material with high performance.

FRP sheet

PET (polyethylene terephthalate) is chemically stable, is recognized worldwide as an environmentally friendly recyclable material, consists of a closed cell structure, is waterproof and moisture resistant, and is the ideal material for many applications.

FAQ

PET foam is made of polyethylene terephthalate or polyester resin. It is a thermoplastic with a closed-cell structure. PET is recyclable and adapts to specific shapes with high mechanical properties.

The R-value (thermal resistance) of PET foam usually depends on its density and thickness. In general, the thermal conductivity of PET foams is 0.03-0.04 W/m-K, corresponding to an R-value of about 0.7-0.9 m²-K/W at a thickness of 25 mm. The exact R-value varies depending on the density of the foam and the application environment.

PET foams can withstand temperatures up to 150°C and are very stable at this temperature. They can maintain their properties.

There are many ways to cut foam, usually as follows:

CNC machining: This machine has high precision and is suitable for cutting complex shapes.
Hot wire cutting: Foam is cut using a heated resistance wire, which is suitable for straight-line cutting.
Hand tools: Foam is best cut with a serrated knife.
Laser cutting: suitable for high-precision cutting of thin materials, but may not be suitable for thick foam.
