Calcium carbonate filler masterbatch is a particle with a volume similar to the base resin of plastic products made by mixing calcium carbonate with carrier resin and mixing and granulating. It has a wide range of application value in the plastics industry. Before masterbatch processing, the surface of calcium carbonate powder is modified to increase its dispersibility, which can greatly improve the crosslinking with the resin. However, there are still 5 issues that need to be paid attention to during the production of calcium carbonate filler masterbatch.

In the quality indicators of raw materials, we often encounter some terms. Accurately understanding their meanings will help us better grasp the performance of raw materials. Here are some commonly used terms.

List of PS modified formulas 1. PS blending 2. Flame retardant reinforced toughened PS/PBT blended alloy material 3. PS flame retardant 4. Halogen-free flame retardant modified HIPS 5. PS foaming 6. Low foaming HIPS plastic paper

The reinforcing materials used in reinforced nylon are mainly fibrous substances such as glass fiber, carbon fiber, and whiskers, among which glass fiber reinforcement is the most widely used. The rigid strength and hardness of the material can be significantly improved through glass fiber reinforcement, and the dimensional stability and heat resistance of the material can be significantly improved. Since nylon itself is not strong enough, 10-30% of fiber is added to increase its strength. In particular, 30% intensity is recognized as the most appropriate ratio.

To improve the film's sliding properties, a sliding additive is introduced during its production (usually the active substances are oleamide and erucamide). After film extrusion, the additive migrates to the surface and creates a sliding layer on it, due to which the friction coefficient is significantly reduced and the film's sliding properties are improved.

Masterbatch is the most common plastic coloring method and is widely used in the plastic processing industry. Dispersion is one of the most important performance indicators of masterbatch. Obviously, dispersion has a vital impact on the quality of plastic products.

CaCO3 powder, also known as calcium carbonate powder, is often added to plastic pellets for the following reasons:1. Reduce costs 2. Improve mechanical properties 3. Density Adjustment 4. Improved processing properties 5. Environmental benefits 6. Improve the heat resistance of plastic products 7. Improve the light diffusion of plastics 8. It can make the product have some special properties

The performance parameters of calcium carbonate have such a great influence on the filling masterbatch! 1. Calcium content 2. Whiteness and hue 3. Water and volatile matter content 4. Particle size distribution 5. Particle shape 6. Content of other components

Several key points that determine the quality of black masterbatch. 1. High dispersion 2. Strong coverage 3. Good liquidity 4. Compatibility should be large

Plastic additives, also known as plastic auxiliaries, are compounds that must be added to polymers (synthetic resins) during molding to improve their processing properties or to improve the performance of the resin itself.
