NC Blowing Agent is a chemical foaming additive designed for PVC foaming products, widely used in the production of foam plates, pipes, profiles, shoe materials and other kinds of foaming products. The NC blowing agent can decompose and produce gas during PVC processing, so that the material forms a foam body with a certain structure, which not only reduces the weight of the product, but also improves the thermal, acoustic and cushioning properties of the product. This white foaming agent is usually a white or light-coloured powder, which is easy to be mixed with PVC resin and other additives, and will not affect the colour of the final product.
