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.
Pvc foam boards its smooth surface, is also printed. (Requires wipe clean surface before printing). Category: transport boats, planes, buses, railway cars, ceiling, car body-core layer, internal decoration plates. Building decoration industry building wall panels, decorative plates, in homes, offices and public buildings across the room, commercial decorative plates, hanging roof racks, dust-free room. Advertising screen printing, computer lettering, advertising signage, display boards, sign boards. Industrial anticorrosive engineering of industrial applications, hot forming, cold storage plates, special cooling plate for engineering, environmental protection.
PVC foam board for other purposes: templates, sports equipment, aquaculture timber, waterfront damp-proof facilities, water resistant materials, art materials, a variety of head Board.
