PVC celuka board can be divided into PVC crust foam board and free foam board according to the production process, appearance, and performance. The PVC skinned foam board is produced by the seluka process, and the surface is covered with a layer of hard skin, which is smooth and flat, with high hardness and good mechanical structure performance. And the product has high precision and small error, and the product has very strict requirements on the quality of the mold, process, and raw materials. The surface hardness of PVC-crusted foam board is very high, it is difficult to produce scratches, and it is widely used in cabinets, decoration, construction, etc. The surface hardness of PVC-free foam board is average, and it is widely used in advertising display boards, mounting boards, silk screen printing, engraving, etc. Next, let's take a look at the performance and characteristics of PVC celuka board.

The performance of PVC celuka board.
PVC foam board is a kind of high hardness and mechanical properties. PVC celuka board generally increases with the increase of molecular weight. Generally speaking, its rigid PVC celuka board has better performance, and its elastic modulus is as high as 1500~3000 MPa. The elasticity of soft PVC celuka board is 1.5~15 MPa. However, the elongation at break is 200% to 450%. The friction coefficient of PVC foam board is general, the static friction coefficient is 0.4~0.5, and the dynamic friction coefficient is 0.23.
PVC celuka board is a polymer with better electrical properties, but because of its relatively large polarity difference, its electrical insulation is not as good as PP and PE. The dielectric loss tangent value and volume resistivity are large, and the corona resistance is not good. It is usually suitable for some insulating structural materials of medium and low voltage and some lower frequencies.
Practical research has proved that PVC celuka board has good thermal insulation, thermal insulation, sound insulation, light load, and other properties, which is better than some other lightweight solid plastic puffed perlite, ceramsite, asbestos products, and other thermal insulation engineering materials. It has the characteristics of a high degree of mechanization development, labor-saving, and time-saving. Using PVC celuka board to make the thermal insulation layer, is used for building roof thermal insulation and external wall thermal insulation. It has unparalleled performance analysis of thermal insulation systems and adhesion performance to the structural layer and also facilitates management of construction, environmental protection, time-saving, efficiency enhancement, etc. many advantages. Has the following functional characteristics:
1. The economical comprehensive cost of PVC celuka board is low.
2. Good thermal insulation performance. The thermal conductivity coefficient is 0.06~0.070W/(M.K), and the thermal resistance is about 10~20 times that of ordinary commercial concrete.
3. The PVC celuka board has low elasticity and shock absorption, and the porosity of the PVC celuka board enables it to develop a low elastic modulus so that it can have a good absorption and dispersion management effect on the impact and load capacity.
4. The PVC celuka board contains a large number of independently existing air bubbles, and the distribution is uniform. The sound absorption capacity is 0.09~0.19%, which is 5 times that of ordinary commercial concrete and has the function of effectively improving sound insulation.
5. The PVC celuka board product can be made into a variety of colors, and its color can remain unchanged for a long time, and it is not easy to age.
