Application of aluminum-plastic co-extrusion micro-foaming technology

Extrusion PVC foam products have many excellent properties, especially PVC low foam products, its comprehensive performance is very outstanding, and ordinary unfoamed PVC products compared with the following advantages:

(1) Low thermal conductivity, that is, good thermal insulation effect;

(2) Excellent acoustic damping, that is, good sound insulation effect;

(3) The secondary molding processing performance is good, similar to wood, can be sawn, nailed, planed, drilled, but also can bond;

(4) High flame retardant, that is, good fire performance;

(5) Stable chemical properties, excellent chemical corrosion resistance;

(6) Excellent weather resistance, while having mothproof, waterproof and other properties;

(7) The use of PVC foaming technology can effectively reduce the content of resin per unit volume of the product, thereby reducing the cost of the product;
