How can you decrease density of PVC profile?
you can decrease it by foaming the PVC resin by adding a foaming agent, the foaming agent is usually in the form of powder where the smaller the grain size the smoother surface you get with smaller bubbles, for a free foaming process you add the foaming agent with the required quantity for the required density (usually the manufacturer specifies it in tables) for example if you need PVC with density of 0.6 g/cm3 add 1.5 % foaming agent (not real values), then you add a catalyst to ensure the homogeneity of the process and all of these compounds together are mixed in hot dry air flow and... I hope this helps u
Why used masterbatch?
The use of color masterbatch has the following advantages: 1. Pigment performs better dispersion in the end-product : The masterbatch is an aggregate made by uniformly loading supernatant pigments in the resin. Colorants in the production process to be refined on the paint to improve the pigment dispersion and color strength. Special masterbatch carrier and plastic products of the same species, with good matching, after heating and melting pigment particles can be well dispersed in the plastic products. 2. Maintain the chemical stability of the pigment: Direct use of paint, because the storage and use of the pigment in the process of direct contact with the air, the pigment will occur water absorption, oxidation and other phenomena, and made color masterbatch, the resin carrier will be pigment and air, water isolation, can make the quality of the pigment long change. 3. To ensure the stability of the product color: Color Masterbatch particles and resin particles similar to the measurement more convenient and accurate, the mixture will not adhere to the container, and the resin mixture is more uniform, so you can ensure the stability of the amount of added, so as to ensure the stability of the product color. 4. Protect the health of the operator: Pigments are usually powdery, add and mix easily when flying, the body will be inhaled after the impact of the health of the operator. 5. Keep the environment clean, do not stain the vessel: 6. Simple process, easy color change, save time and raw materials: As the pigment in the storage and use of direct contact with the air, so there will be moisture absorption, oxidation, agglomeration and other phenomena, the direct use of plastic products in the surface of the color point, hue dark, easy to fade color, and caused by mixing Dust Feiyang, affecting the health of the operator. The masterbatch in the production process by mechanical processing, the pigment was refined, the pigment and resin carrier, dispersant fully mixed, so that the pigment and air, water isolation, thereby enhancing the pigment weather resistance.
