Spraying-free products refer to plastic materials that are directly added with colored pigments and then processed into different plastic products by injection molding or extrusion process. The product itself has different effects (pearlescent, metallic or natural texture, etc.) and does not need to be sprayed again.
Compared to spraying products, spraying-free products have many advantages:
✔Eco-friendly: No spraying is required during processing, which greatly reduces VOCs emission
✔High efficiency: One-step molding without surface treatment
✔Low cost: Reduced by 30-50%
✔ Design freedom: Aesthetic appearances of various textures can be achieved to support designers’ artistic creativity.
✔Recyclable: The product can be 100% recycled
Spraying-free products quickly gained attention on the market, and household appliances and automobile brands have already started to use them.
However, it is not easy for the spraying-free products to completely replace the spraying ones. The two long-standing difficulties in the industry, flow marks and weld lines, have become the biggest obstacles to the large-scale application of spraying-free plastic products.
Wanhua Chemical introduces spraying-free polycarbonate aesthetic resins, making full use of the advanced polymer blending modification research and development platforms and the perfect evaluation system. By designing the raw material synthesis process and developing compatilizer polymerization technology, the pigment particles can be well infiltrated and uniformly dispersed in the matrix, and the problems of flow marks and weld lines of spraying-free products can be easily solved without changing the mold.
Product features:
