Introduction to the advantages of sandwich panels




Sandwich panel products are composed of two-layer formed metal panels (or panels of other materials) and a polymer heat-insulating inner core directly foamed and cured in the middle of the panels. A board made of high-strength surface material and a core material with lighter bulk density and less strength.

Its main advantages are:
①The specific strength of the plate is high.
② The core material is cheap and the amount is large, and the surface material is high in price and the amount is small, so the production cost of this product is low.
③ Reasonable selection and matching of surface and core materials can effectively meet the pre-designed sheet performance requirements.

For example, metal cladding is used to improve the fire resistance and water resistance of the board, and decorative board or plastic sheet is used as the surface layer to improve its decorative effect.
