Raw materials used in PMI foam

Summary:Polystyrene foam board, also known as foam board, EPS board,...

Polystyrene foam board, also known as foam board, EPS board, is a white object that is made of expandable polystyrene beads containing volatile liquid foaming agent, which is pre-heated and molded in a mold. PMI foam has the characteristics of fine closed-cell structure. It is mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration and carving, etc. It is very versatile.


PMI foam can effectively eliminate "thermal bridges". In the past, internal insulation was used. "Heat bridges" were unavoidable. External wall insulation effectively prevented thermal bridges from forming and avoid condensation. Protect the main structure of the building to extend the life of the building. Because the external thermal insulation is to place the thermal insulation layer on the outside of the structure, it reduces the pressure generated by the structural deformation caused by temperature changes, and reduces the corrosion of the structure by harmful substances in the air and ultraviolet rays. Increasing the use area of ​​the house can avoid damage to the thermal insulation layer due to secondary decoration.


PMI foam improves the moisture temperature of the wall. Generally, internal insulation requires a vapor barrier. The temperature permeability of external thermal insulation materials is much stronger than that of the main structure. Condensation does not generally occur inside the wall. PMI foam The temperature increase of the entire wall of the structural layer further enhances the insulation performance of the wall. It is conducive to the stability of the room temperature, and the use of external insulation of the outer wall, because the structural layer with greater heat storage capacity of the wall is on the inner side of the wall, it is conducive to the stability of the room temperature.


PMI foam is a kind of construction material. Generally, the place where this material is used is to make it fireproof and soundproof, so this material is more suitable for use in some public places. Core material foam is more suitable for fire and sound insulation in these places, such as office partitions, dance halls, shopping malls, gymnasiums, etc. These places are suitable for decoration.


There are also some good sound insulation effects, such as broadcasting studios, recording studios, etc., where sound insulation effects are better. When choosing this material, we must first understand its performance, so that we know where it is suitable for use.
