Filled (CaCO3 Calcite) Compounds
High-Performance Calcite (CaCO₃) Filled Compound Production with Monomex
Monomex offers twin-screw extrusion lines and process solutions specifically designed for the production of high-quality calcite (CaCO₃) filled compounds. Calcite additives used in polymer-based systems such as polyethylene (PE) and polypropylene (PP) are homogenously dispersed using Monomex technology. This ensures excellent mechanical properties, low cost, and sustainable production in final products, even with high filler ratios.
Monomex Compound Solutions and Application Areas
Monomex compound solutions serve a wide range of industrial applications, including packaging, automotive, white goods, pipe, and sheet production.
Application Areas:
Packaging Films and Bags
Injection Molding Products
Pipe and Profile Production
Sheet and Plate Production
Integrated Recycling Systems
Homogenous Dispersion Guaranteed with Monomex Extruder Screws
Monomex extruder screws offer maximum efficiency and durability in processing abrasive and dense filler materials like calcite, providing long-lasting use through special geometries and surface coatings. This ensures production stability, low maintenance requirements, and high product quality.
High Dosing Accuracy in Feeding Equipment
Monomex feeding systems guarantee stability and quality in compound production by ensuring accurate dosing of calcite, additives, and polymers. These systems, which can be configured for each production recipe, facilitate process control.
Manufacturing Systems and Infrastructures
With extensive engineering knowledge and industry experience, Monomex provides optimized production systems and infrastructures for filler-based (e.g., CaCO₃ / calcite) compound production. Especially in processing recipes with high filler density, it stands out with homogeneous mixing, low energy consumption, and durable equipment design.
Monomex production lines are equipped with twin-screw extruder technology for both granular and masterbatch solutions, ensuring stable and high-quality production despite high filler ratios.
Advantages and Applications of Calcite Filled Compounds
CaCO₃ (calcite: marble powder, limestone) is used as a filler material, especially in compounds with PP and PE carriers. Calcite finds application in almost every industry. Particularly, bag manufacturers prepare formulations by using 50% calcite-filled compound when extruding film. This not only makes the product more cost-effective but also increases its durability. Some bag manufacturers even directly produce bags from 65% calcite-filled compound granules manufactured on Monomex extruders.
Key application areas include LDPE film, HDPE film, corrugated pipes, PP sacks, injection molding, PS extrusion (HIPS Antishock), thermoforming, and raffia applications. They can be formulated with various reinforcing agents such as impact-resistant, UV stabilized, and antistatic properties according to desired specifications.
Example Formulation: 75% Antisplit (Mixture) = 75% OMYA 2XT-KA Calcite, 0.09% Wax, 0.03% Calcium Stearate, 23.8% Sabic LLDPE 118W
In general, these compounds provide a 10-15% increase in extruder efficiency due to the higher heat transfer coefficient of fillers compared to polyolefins. The regular flow within the extruder ensures the dimensional stability of the film/profile. As the friction coefficient decreases, static electricity also reduces. Additionally, it lowers raw material costs and enhances the heat-sealing properties of polyolefins.
