What is PVC Foam Board?
The PVC foam board is also known as Chevron board and Andy board, its chemical composition is polyvinyl chloride. PVC foam boards are widely used in buses, train cars ceiling box core layer, interior panels, the external walls of the building board, decoration board, office, residential and public building, commercial decorative frame, clean room with a plate, ceiling panels, screen printing, computer lettering, advertising label, display panels, signs with the board albums boards and other industries and chemical anti-corrosion engineering, thermoforming parts, cold storage with a board, special cold project environmental formwork, sports equipment, farming with material waterfront facilities, moisture, water-resistant materials, art materials and a variety of portable partition instead of the glass ceiling, etc.
PVC Foam Board Features and Performance
Pvc foam board has the performance of sound insulation, sound absorption and insulation; the PVC foam sheet quality is flame retardant, and it can be self-extinguishing eventuality of fire, it is safe to use; PVC foam board products are moisture-proof, anti- mildew, non-absorbent performance, and shock effect; colors of PVC foam board products can keep the bright colors after being weather resistance formulated over the long term, not aging; PVC foam board is light in texture, easy to store and transport, convenient construction; PVC the foam board general wood processing tools to construction; PVC foam board is the same as wood drilling, sawing, nailing, planning, sticky processing; PVC is applicable to thermoforming PVC foam board, heat bending and folding process; foam board can be welded or bonded with other PVC materials; PVC foam board has smooth surface and easy for printing.
Key Points of PVC Foam Board Process
The foam pvc mouldings are divided into three processes: the formation of the bubble nucleus, the expansion of the cell nuclei, and the curing of the foam. For PVC foam sheet, adding a chemical foaming agent, the expansion of the bubble nucleus has a decisive influence on the quality of the expanded sheet. PVC is a straight-chain molecules, the molecular chain is short, low melt strength in the process of cell nuclei inflated into a bubble, the melt is insufficient to coat the bubbles, the gas easily overflow into large bubbles, and to reduce the foam sheet of product quality . The key factor in improving the quality of PVC foam sheet is to improve the melt strength of the PVC. From the processing characteristics of polymer materials, PVC melt strength in a variety of ways, but the most effective way is added to improve the melt strength additives and lower processing temperatures. PVC belongs to amorphous materials, the melt strength decreases with the increasing of melt temperature, and on the contrary, melt strength increases with the reduce of melt temperature, the cooling effect is limited and it only plays a supporting role.

Introduction to Foam Board
The Use of Foam Board
The polystyrene foam board is also known as foam board, EPS board is a kind of white object made by the expandable polystyrene beads containing volatile liquid blowing agent, heated in the mold after pre heating the molding. It has the structural characteristics of minuteness obturator, and it is mainly used for building walls, roof insulation, composite board insulation, cold storage, air-conditioned vehicle, ship insulation, floor heating and decoration carving. The application purposes are very extensive.
Advantages of Foam Board
First, it can protect the main structure of the building, to extend the building life. Since the outer insulation is placed in a structure outside of the insulation layer, reduce the stress generated due to structural deformation caused by temperature changes, and reduce the erosion of the structure of the air of harmful substances and UV. Second, the white foam board can effectively eliminate “thermal bridges". In the past, we use the internal thermal insulation, so it is difficult to avoid “thermal bridges”, and the external wall insulation can prevent the generation of thermal bridges, to avoid condensation. Third, wall humid is improved, generally within the insulation vapor barrier to be located, while the use of exterior insulation materials through temperature performance is far stronger than the main structure. Generally, it does not generate condensation within the wall structure layer. Fourth, good to keep stable the room temperature, the exterior insulation, He held stable because the larger structural layer of the heat storage capacity of the wall inside of the wall, there is conducive to the room temperature. Last, to increase the use of housing area, can avoid the damage to the insulation layer due to re-decoration.
PVC Foam Board
PVC foam board is also known as Chevron board and Andy board, its chemical composition is polyvinyl chloride. The surface of the compaction leather board of PVC foam board is very smooth, high hardness, not easy to scratch, it is an ideal substitute commonly used in making cabinets, furniture, wood, aluminum and composite sheet. pvc foam board has the features of anti corrosion, anti moisture, anti mildew, non-absorbent, drilling, sawing and planing, easy to thermoforming and hot bending. It is widely used in passenger cars, the roof of the train cars, box core layer, interior panels, building wall panels, interior panels, office, residential, public building, commercial decorative frame, clean room panels, ceiling panels, screen printing, computer lettering, advertising, labeling, displays, signs with the board albums boards and other industries and chemical anti-corrosion engineering, thermoforming parts, cold storage with a board, special cold project environmental formwork, sports equipment, breeding materials, waterfront facilities, moisture, water-resistant materials, art materials and a variety of light partition instead of the glass ceiling.
