Three aspects of the difference between foam board and KT board
Many people make foam sheets and KT boards as expandable polystyrene beads. KT board is considered to be the abbreviation of foam board and is a "thin" foam board. So the fact is not the case, what is the difference between the foam board and the KT board? The following is an analysis from three aspects.
Structural components of the two
Polystyrene foam board - also known as foam board, EPS board, is a white object that is heated and formed in a mold by heating expandable polystyrene beads containing volatile liquid foaming agent.
KT board is a new type of material which is formed by chemical particle granules which are foamed to form a core and pressed through a surface film. The main ingredient also contains polystyrene. Commonly used production processes can be divided into cold composite and thermal composite. The products produced by these two different processes are called (cold composite board) cold plates and (hot composite board) hot plates. The color of the KT board core is commonly used in white and black, but also in red, blue, yellow, green and other colors. However, there is no domestic demand, so no manufacturer will go to production. However, there are these colored kt boards in the exit KT board.
The advantages of both
Foam board
The foam board itself has the advantages of low density, high recovery rate, and independent bubble structure. Secondly, the surface water absorption rate is low and the penetration resistance is good. It is also resistant to acid, alkali, salt, oil and other organic solvents, and has excellent aging resistance. More valuable is that it does not flow at high temperatures and does not crack at low temperatures.
Advantages in the common construction field:
1. Protect the main structure of the building and extend the life of the building. Since the external insulation is placed on the outside of the structure, the stress caused by the structural deformation caused by the temperature change is reduced, and the harmful substances in the air and the ultraviolet rays are eroded.
2. Effectively eliminate the “heat bridge†used in the past, “heat bridge†is difficult to avoid, and the external wall insulation effectively prevents the generation of heat bridge and avoids condensation.
3. The wall moisture temperature condition is improved. Generally, the inner insulation needs to be provided with a vapor barrier layer, and the temperature permeability of the external thermal insulation material is far stronger than the main structure, and condensation does not generally occur inside the wall. The increased temperature of the entire wall further enhances the insulation properties of the wall.
4. Conducive to the stability of room temperature, the use of external thermal insulation, due to the wall heat storage capacity of the structural layer on the inside of the wall, is conducive to room temperature stability.
5. Increase the area of ​​the house. It can avoid the damage of the insulation layer caused by the secondary decoration.
KT board advantages:
1. The foaming of the foaming hot plate is mostly caused by the short curing period and the thin skin, and the cold plate foaming is mostly caused by poor coating or long direct sunlight.
2. Comparison of prices: The price of hot plates is low, mainly due to the short production period, less material used and large production volume, while the cold plate is just the opposite.
3, KT board mask on the more types, common PS surface, paper surface, adhesive surface and other types.
4, kt board is used in indoor advertising, the general requirements for the board is to ensure no bubbles and no deformation.
Application areas of the two
Foam board is mainly used for building wall, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration and so on.
KT board mainly applies to the advertising industry, the signage industry, as well as in the architectural decoration industry, culture and art and packaging industry, printing industry, cosplay props.
It can be seen that both the foam board and the KT board are produced by the same mother (polystyrene), but due to various processes, the generated objects have different structures and have their respective application fields.

Luminous Pressure Gauge
Luminous pressure gauge uses energy storage noctilucent powder as dial material which will glimmer for a long time after a few minutes of lighting so that the pressure gauge can be clearly read in the darkness. It is applicable for the support of diving gears and firefighting, live-saving equipment.
