Calcium Carbonate masterbatch – Filler masterbatch
Product Advantages
Ⅰ：CaCO3 Filler masterbatch is a compound composed of calcium carbonate, virgin polyethylene resin and other dispersed plastic additives.
Ⅱ：Calcium Carbonate Filler is used as a filler to reduce the cost of the product, impart opacity, and increase stiffness to shaped products.
Ⅲ：This filler is compatible with virgin and recycled plastics (PP, PE, ABS, etc.) and is widely used in the production of woven PP bags and PP ropes with a high mixing ratio (5% - 50%)
Product Details
Our PP filler masterbatch combines the purest materials and technologies to provide customers with not only cost-effective solutions but also high-quality finished products.
PP filler masterbatch is a filler masterbatch containing 70-85% ultrafine calcium carbonate in base polypropylene. It reduces the volume formulation cost of the final product without compromising the quality (color, purity, dispersion and smoothness of the product surface). In addition, PP filler masterbatch can improve the impact force, surface hardness, strength duration and elongation of the product.

Applications
Filler masterbatches are used in injection molding, blow molding, film (single or multi-layer), sheet and tape applications. They offer the following benefits:
a) Injection and blow molding
Increased production due to faster mold cooling
Higher resistance to heat distortion, increased stiffness and hardness
In injection and blow molding applications, filler masterbatches can be added at rates up to 50%, but the most common levels are between 5-30%.
b) Film, Sheet, Sacks, Bags, Raffia
Higher stiffness, paper-like effect
Improved weldability and printability
In film applications, FILLER masterbatches are added at rates of 2-20%.
c) PE and PP tapes
Anti-fibrillation (also known as anti-splitting)
Lower raw material costs as they are often more economical than polymer resins
Improved weaving ability
Easier processing
In tapes, FILLER masterbatches are typically added at rates of 3-8%.
d) HDPE and PP pipes
High whiteness, can replace expensive white masterbatch
Low raw material cost, usually more economical than polymer resin
Higher stiffness
Good cold resistance, not easy to brittle at low temperature
The addition amount of FILLER masterbatch in the tape is generally 5-30%.
