| Performance: |
| 1. The filling amount in the profile reaches 20-30 parts, and the various performance indexes of the profile can still meet or exceed the requirements of international standards, which significantly improves the surface gloss of the product. |
| 2. Under the premise of unchanged original formula, adding NPCC-202 product, the low-temperature drop weight and cold punching performance are basically unchanged, which can increase the welding corner strength and significantly reduce costs. |
| 3. The addition amount of national standard parts is 8-12% under normal circumstances. After adding nano-calcium carbonate, please note that the load is the same as usual during use. If the load is low, it is recommended to reduce the lubricant by a quarter. To one third of the dosage. After using this product, the amount of processing aids (such as ACR, CPE) and heat stabilizers other than lead can be appropriately reduced. |
| 4. The processing of the profile is easier to control. |
| 5. The appearance of the profile can be improved, and the frost and "oil" migration will not occur on the surface of the product. |
