Calcium carbonate masterbatches contain a high percentage of calcium carbonate powder mixed with primary resin and several appropriate additives. The masterbatch is used as filler in plastic-based product manufacturing. It replaces a part of input material that helps producers save production costs and enhance several properties of final products at the same time.
The masterbatch increases whiteness and facilitates pigment dispersion in plastic mixtures contributing to the higher opacity of finished products.
This Article Highlights The 4 Applications Of Calcium Filler Masterbatches:
1. Generating Non-Woven fabric
Calcium carbonate fillers for generating non-woven fabric ranging from medical to personal care like hygiene and geotextiles. There are multiple benefits to adding calcium carbonate to generate non-woven material:
- Offering natural white colour to the fabric with limited yellowness
- Increasing the thermal conductivity and physical strength of the fabric
- It efficiently cooperates with multiple base resins due to its good dispersion ability and can be processed by various methods.
- Improves the fabric surfaces by reducing lustre, making the surface more matte and opaque and enhancing the covering ability of the fabric structure.
- Creates more micro areas for air filtration and oil absorption.
2. Yarn and Twine Manufacturing
Filler Masterbatches For Anti Fibrillation are the perfect solution that helps manufacturers either reduce partly or altogether avoid fibrillation problems. Fibrillation is a common problem in the yarn and twine manufacturing process that causes uncontrolled splitting when the PP or PE yarn gets stretched. When calcium carbonate fillers are added to flat PP/PE yarn production, the fibrillation problem gets solved. Masterbatches for fibrillation also offers benefits such as:
- Offers anti-slip and anti-blocking properties, facilitating winding step
- Improves tensile strength and tearing resistance of the woven fabric and flat yarn post stretching
- Improves printability, weaving ability and weldability
- Increased product productivity.
3. Injection Moulding
When calcium carbonate fillers are mixed with PP masterbatch — it becomes the ideal solution for manufacturing household appliances such as boxes, bottles, furniture, etc., via the injection moulding method.
Products manufactured by combining PP resin and calcium carbonate masterbatch have advanced thermal conductivity, impact resistance and better flexural stiffness with lower shrinkage.
4. Films And Sheet Extrusion
Calcium carbonate masterbatches can be directly added into virgin plastic, and the mixtures function as filler and additive masterbatch simultaneously for manufacturing sheets and plastic films. They offer higher blocking, slipping resistance, folding and creasing qualities. They also offer high tensile strength to the finished products by allowing protection even when stretched. The material is also safe to contact with food as it does not contain toxic elements.
