After the PVC recycled materials are granulated, the downstream customers will find that the products made from them will not have enough gloss after using the PVC particles. The reason for this is often that the PVC recycled materials manufacturers will add calcium powder when granulating the recycled materials to reduce the production cost, and the calcium powder will cause matting, so it often leads to the gloss not meeting the customer’s requirements when the PVC products are injected after granulation.
How to improve the surface gloss of products granulated from PVC recycled materials?
PVC recycled materials granulation manufacturers have tried to add many plastic additives to improve the surface gloss of PVC injection molded products, but none of them have achieved good results. PVC recycled materials granulation manufacturers therefore wanted to try again and use silicone series additives to solve the problem. After comparing online, PVC recycled materials granulation manufacturers decided to choose Baozhuan New Materials ‘ silicone powder for testing.
How to improve the surface gloss of products granulated from PVC recycled materials? After
the PVC recycling granulation manufacturer connected with the technical engineer of Baozhuan Company and communicated with him about the processing technology, the technical engineer of Baozhuan recommended that the PVC recycling granulation manufacturer add a proportion of 0.8%. So the PVC recycling granulation manufacturer conducted a test. After the test, the PVC recycling granulation manufacturer found that the glossiness of the particles on the surface of the PVC was significantly improved, meeting the glossiness requirements.
The main solution principle: The recycled PVC itself contains calcium powder, but our silicone powder contains silicone oil. As long as the coating is good, the glossiness will be improved. Another point is that the internal and external lubrication effect is improved, the screw mixing strength is better, and the discharge effect is more uniform, which can also improve the glossiness of the product.
