NF EPS steel wall sandwich panels are combined with steel sheets and expanded NF polystyrene.This kind of sandwich panels were originally from South Korea. The basic principle is to use the particle fire barrier technology. The copolymer modification is used to make the EPS monomer particles have the same characteristics as the fireproof material, and the micro phase conforming technology is used to form the fireproof separator on the surface of each organic particle. So that each particle forms a relatively independent organic particle fire protection unit.

2. Panel Advantages:

1) Excellent fire performance:

● Achieve A grade fire resistant level, this product has passed the non-combustible level test of insulation materials;

● The principle of particle fireproof isolation bin is used to realize fire retardant effect;

● The production adopts the thermosetting molding process, and the product has the performance of burning the thermosetting material. After the product is burned, it is carbonized without dripping, which can avoid the generation of pool fire and secondary combustion;

2) Efficient insulation performance:

● The thermal conductivity of sandwich panel is 0.032-0.036, and the thermal insulation performance is obviously superior to other A-grade fireproof thermal insulation materials.

3) Green energy saving and environmental protection:

● The product itself does not contain toxic substances.Brominated flame retardants will be banned in the next two years. At present, Europe has begun to ban. This product has got rid of the is understanding of increasing the amount of brominated flame retardants to improve the flame retardant performance. The flame retardant effect is achieved by adding an inorganic filler to modify the expandable polystyrene;

● The products are environmentally friendly, no harmful substances are volatilized, no decomposition and no mildew, the product burns low smoke, and does not produce toxic and polluting environmental gases;

● Product production process is low energy consumption, no pollution;

● Product is recycling.

4) Good ventilation

5) Product application cost-effective

3. Panel applications:

NF EPS insulated sandwich panels could offer a complete usage for commercial residential, agricultural and USDA food grade buildings,and all the designs could meet up customers individual needs.

4. Panel fire level description:

NF EPS is actually meaning Nonflammable (Fireproof) expanded polystyrene,which has excellent thermal insulation performance, fire prevention performance of A, B1-class non-combustible.

The principle of NF EPS fire retardant is polymer technology,which is not as simple as just adding flame retardant material into EPS board, it makes the thermoplastic EPS into thermosetting EPS,maybe we should call it thermosetting modified technology.

5. Delivery information:

1) Max length for wall or roof panel: 11.9 m Longer panels available on 40FT container and 5.9 m long panels available on 20FT container;

2) Min. standard length roof and wall panel is 2 m;

3) All sandwich panels are supplied with an PVC film seal on the surface sheets;

4) Panel loading quantity reference:

7. FAQ about NF fireproof sandwich panels:

1) What’s NF EPS sandwich panels?

NF EPS sandwich panels is one kind of structural insulated sandwich panels,which is combined metal sheets with Nonflammable EPS core material.It could be widely used in different kinds of buildings,such as office buildings, steel warehouses, food storage room, etc.

2) What’s the difference between EPS and NF EPS sandwich panels?

The main difference is the core material.EPS is expanded polystyrene,which is with fire resistant material and makes it could be fire resistant core material,the fire resistant level is B1.And NF EPS is Nonflammable (Fireproof) expanded polystyrene,and fireproof level is A.
