Calcium carbonate is an inorganic compound with the chemical formula CaCO3, which is the main component of limestone, marble, and other materials. Calcium carbonate is usually a white crystal, odorless, essentially insoluble in water, and easily reacts with acids to release carbon dioxide. It is one of the common substances on Earth, found in rocks such as aragonite, calcite, chalk, limestone, marble, and limestone, and is also a major component of certain animal bones or shells.

Film

 

Currently, calcium carbonate is used in various applications ranging from thin films to thick plates to enhance mechanical properties and increase production capacity. The application of calcium carbonate can not only improve the impact strength and stiffness performance, but also increase the production capacity of the production line.

 

 

Our calcium carbonate series products, specially developed for the film industry, have become recognized as benchmark products in the global film industry through technologies such as controlling the maximum particle size, calcium carbonate purity, and surface coating.

① The adhesive force is enhanced

 

② The minimum sealing temperature decreases

 

③ Lower processing temperature

 

④ Reduction in shrinkage

 

Sheet

 

Adding up to 60% calcium carbonate filler to polypropylene for use in polystyrene thermoforming machines has been proven to be a feasible solution that can achieve suitable production capacity and ensure final product quality.

 

The use of calcium carbonate in polystyrene products is a very popular practice, which can adjust the mechanical properties of the product and improve the production capacity of the production line.

 

The main benefits of using our calcium carbonate in hot forming applications include:

 

• Higher extrusion capacity and faster roll cooling speed

 

• The cooling time inside the mold is reduced, and the production cycle is accelerated

 

•  Higher stiffness

 

• Lower shrinkage rate

 

•  Can be directly used on existing polystyrene thermoforming machines

 

• More isotropic physical properties

 

• Improved forming accuracy

 

 

Silk Ribbon

 

 

The ribbon in the woven bag industry also benefits from extremely fine activated calcium carbonate, which provides excellent mechanical properties and maintains outstanding product quality while continuously increasing the amount of calcium carbonate added.

The main benefits of the production process include:

 

① Directional polypropylene reduces cracking tendency

 

② Increased stiffness

 

③ Controlled water carrying capacity

 

Molding

 

 

The high thermal conductivity and low specific heat of calcium carbonate are its key advantages in molding applications.

 

In injection molding and blow molding applications, cycle time, stiffness, and impact resistance are all improved, resulting in cost reduction

 

Blow Molding

 

Calcium carbonate has numerous advantages in blow molding applications for the production of bottles and containers, such as:

 

• Increase bending modulus

 

• Increase the ability to withstand long-term stacking loads and drop strength

 

• Better resistance to chemical environment stress fracture ability

 

•  Shorter production cycle time

 

• Lower melting temperature

 

•  Can reduce the amount of titanium dioxide used

 

• Better printing performance

 

Injection Molding

The main benefits of using our calcium carbonate include:

 

① Higher stiffness

 

② Better impact strength

 

③ Less shrinkage rate

 

④ Better dimensional stability

 

⑤ Higher thermal deformation temperature

 

⑥ Shorter production cycle time
