What is a PVC Foam Board?
PVC foam board is also known as Chevron board and Andy board, its chemical composition is polyvinyl chloride. PVC foam board has the characteristics of anti-corrosion, anti-moisture, anti-mildew, non-absorbent, can be drilled, sawn and planed, easy thermoforming and hot bending. PVC foam boards are widely used in passenger cars, the roof of the train cars, box core layer, interior panels, building wall panels, interior trim plate, office, residential, public places, buildings compartment commercial decorative frame, clean room panels, ceiling panels, screen printing, computer lettering, advertising, labeling, display panels, logo plate album board industry and chemical corrosion engineering, thermoforming parts, cold storage panels, special cold project, environmental protection formwork, sports equipment, breeding materials, waterfront anti- moisture facilities, water-resistant materials, art materials and a variety of portable partition instead of the glass ceiling, etc.
Extrusion PVC Foam Board Features
Applications of extrusion pvc mouldings products have been used in international in the early 60s of the last century and after nearly 40 years of continuous research and development, PVC foam technology and application have achieved a lot of development in these two areas. It gets more rapid development in recent years, but its importance is also constantly improving. This is because the PVC foam products have many excellent properties, in particular the comprehensive performance of the PVC foam products is very prominent, and compared with the general non-foam PVC products, it has the following advantages: low thermal conductivity, thermal insulation effect is good; excellent acoustic damping ability, good sound insulation; the secondary forming performance, similar to wood, sawing, nailing, planing drilling, also bonds; high flame resistance, fire performance; chemical stability, excellent chemical resistance; excellent weather resistance and mothproof, waterproof performance; PVC low foaming products have no pollution to the environment and can be recycled, they are green products.
Extruded PVC Moulding Process
Process for extruded foam products in the world is various, such as the Reifenhauser process method; Celuka process method; BASF process method; Armocel Craft Sale method. Free foam method and controlled foaming extrusion foaming method can be divided into two basic methods. Practice has proved that the PVC low foam molding technology has its own particularity, mainly there are two-folds: on the one hand, the production technology of PVC foam products have special requirements for production of raw materials, formulations, equipment and molds, and it differs from non-foaming products; On the other hand, due to there are many factors affecting the foaming foam and as well as the process equipment at the same time, so it is difficult to master the production technology.
