| 1. On the premise of keeping the original formula unchanged, the direct addition of PVC functional nano calcium carbonate products to PVC products significantly improves the fluidity of the polymer, and has excellent plasticization and processing properties. The fluidity of the polymer is greatly improved, the scrap rate is reduced, and the extrusion load is reduced by 5-10%. By reducing the amount of internal and external lubricants, excellent physical and mechanical properties can be obtained. |
| 2. The filling amount in the polymer is more than doubled compared with other powders, while the performance remains unchanged. Directly add 30-80% functional special-purpose nano calcium carbonate (based on the amount of calcium carbonate in the original formula) to various types of PVC products to reduce product costs. |
| 3. Appropriate addition of this product in other polyolefin (PP, PE, PPR, PS, ABS) and other products can significantly send the tensile and impact strength of the product. |
| 4. It can give the final product extremely strong yellowing resistance and heat aging resistance. Make the final product has a strong ability to resist yellowing, and maintain the original gloss for a long time. In appearance, the whiteness is obviously higher than the original, and there is no frost phenomenon. |
| Scope of use: PVC pipe fittings, wood-plastic flooring, gussets, films, wires, cable sheath rubber particles, pipes, shoe soles, etc. |
| The use method of PVC nano-special calcium carbonate for PVC pipe fittings (alternative type) |
| Non-standard parts are added to 50-70 parts of nano-calcium carbonate for PVC pipe fittings, generally 50 parts are added. |
| Add 20-30 parts of standard calcium carbonate for PVC pipe fittings as standard parts, usually 20 parts. |
| General formula such as: adding 12 parts of ordinary calcium carbonate, adding 25 parts of nano calcium carbonate for PVC pipe fittings. It has improved gloss, improved impact strength, toughening and strengthening, and has anti-aging properties. |
| Method for using PVC functional nano calcium carbonate for pipes |
| Add 12.5 parts, the formula remains unchanged, you can reduce the lubricant properly |
| The use of PVC functional nano calcium carbonate for PVC cable materials |
| The amount of nano-calcium carbonate that can be added to the national standard is 40 parts |
| The use method of PVC special nano calcium carbonate for PVC gusset and wood plastic floor |
| Adding 15 parts of PVC functional nano-calcium carbonate products on the basis of unchanged original formula can improve the surface gloss of PVC gussets and wood-plastic floors, and improve the strength and toughness of products. |
