Introduction and use characteristics of high temperature resistant foam:


The high temperature resistant foam has very good cushioning performance, and its main function is to protect the package from shock, drop, pressure and pressure; the heavier the weight, the higher the density and the harder the hardness. However, it is slightly thinner than the thickness of 1 cm, and the protection effect is not ideal. It is recommended that the most suitable thickness is still 1.5 cm or more, and the buffering effect is much better. In terms of hardness, 9 density material is slightly soft; 12 density material, moderate hardness, suitable for most packaging protection; 15 density material medium to high, suitable for packaging requirements; 18 density material is generally hard material, suitable For heavier items, it can also be used for other purposes (insulation, model, etc.); 25 density material is a special hard material, and its hardness is similar to that of a packaged foam box for packaging appliances.


Uses: Mainly used for building wall, roof insulation, composite board insulation, cold storage, air conditioning, vehicles, ship insulation, floor heating, decoration and engraving, etc. Features: If the high temperature resistant foam board is used in the external thermal insulation system, the apparent density shall comply with the requirements of JG149-2003 "Expanded polystyrene board thin plastering exterior insulation system" standard, namely apparent density. At 18 to 22 kg/m3; maintain the main body layout of the building and extend the life of the building. Because the external insulation is placed on the outside of the layout, the stress caused by the deformation of the layout caused by the temperature change is reduced, and the corrosion of harmful substances and ultraviolet rays in the air is reduced.


The high temperature resistant foam is good for maintaining the stability at room temperature. The exterior wall insulation is used. Because the wall is stored with heat, the larger layout layer is on the inner side of the wall, which is beneficial to the stability of the room temperature. The polystyrene material is light, shockproof and resistant. The advantages of falling, heat insulation, sound absorption, heat preservation, self-extinguishing, environmental protection, anti-aging, low cost, easy construction, etc. are widely used in the construction and packaging industry; when the foaming EPS beads are heated above 90 °C, the beads soften and develop. The foaming of the foaming agent can expand the EPS beads by 40-80 times.
