Function of various Core Materials of sandwich panel

Apr. 27, 2018

1. EPS SANDWICH PANEL: the colored steel plate is made of EPS particles, shaped like chemical fertilizer particles, which are heated and foamed to form large particles like white pearls. The foamed plastic sheet with fine closed pore structure is made by heating and pressing in the mould.

2.Polyurethane: fire-resistant heat preservation performance of the material, used in the composite board polyurethane bulk density generally in 30 kg-40 kg.

3. ROCK WOOL SANDWICH PANEL: Black Tortoise stone is used as the main raw material, after melting at high temperature, inorganic fiber is made from high speed centrifuge, and at the same time, a certain proportion of binder is added to bake to form a large plate, and the wicker is cut according to the need of the basin. Rock wool is a non-combustible body with good fire resistance.

4.GLASS FIBER SANDWICH PANEL: is a light, heat resistant, elastic, otherwise insulation materials, widely used in chemical, medicine, factories, heavy industrial machinery, construction, vehicles and ships, aerospace, is an ideal heat-breaking, fire-proof, sound-absorbing materials.

5, PAPER HONEYCOMB CORE SANDWICH PANEL: colored steel plate is the national B1 class fire proof material, with good flame retardancy, good compressive strength, only carbonation and non-combustion, no toxic substances, and the waste can be received and reused completely. It is polystyrene, polyurethane, etc. The ideal substitute for rock wool core material.
