In the food processing industry, the choice of packaging materials is crucial. Imagine if you could use a material that not only improves the safety of food packaging, but also extends the shelf life and improves the consumer experience. Is such a material worth a deeper understanding? Our Talc Powder For Food Packaging Plastics is just like this, it shows amazing versatility in food packaging plastics.

Calcium carbonate (CaCO₃) is a common inorganic compound that is widely found in nature, mainly in the form of limestone, marble, and chalk. It has a wide range of applications and plays an important role in many industries and daily life. This article will explore the main uses of calcium carbonate and its application in different fields.

Talc, because of its unique set of physicochemical properties, is one of the most popular reinforcing and modifying fillers in industries such as rubber, plastics and paints. Some of the properties that characterize talc are its lubricity, non-sticking properties, ease of flow, fire resistance, resistance to acids, insulation, high melting point, chemical inertness, good coverage, soft gloss, and strong adsorption. Through these excellent properties, the shape stability, tensile strength, shear strength, flexural strength, compressive strength, elongation, coefficient of thermal expansion, brightness, and particle size distribution of products are all significantly impacted by the use of talc.

In a nutshell: Dry whiteness is the face, while wet whiteness is the substance. Only by choosing the right talcum powder with high moisture whiteness can loose powder and powder compacts achieve the following: fine texture without powder flaking, bright whiteness without mask, and long-lasting makeup without dullness.

Nowadays,if you are considering the selection of flame retardant fillers for halogen-free systems, the materials that you will probably come across most often are MDH and ATH. Both are eco-friendly and non-halogenated flame retardants that find a wide application in cable compounds, EVA, rubber, and engineering plastics. However, their performances vary greatly depending on the processing temperature, the amount of the filler, and the end-use application. This article will provide you with a detailed comparison between MDH and ATH at the technical level so that you can better understand and select the appropriate ‍‍‌product.

​As a plastics modification company, we cannot simply view talc as a "cheap filler to reduce costs." From a physicochemical and crystallographic perspective, talc is a functional mineral with unique microscopic geometry, complex surface chemistry, and nucleation effects. Below, I will move beyond the general notion of "increasing rigidity and reducing costs" and provide an in-depth analysis of the structural essence and modification mechanism of talc.

The primary reasons are its low solubility in water and the fact that the dissolved portion only partially dissociates to release hydroxide ions (OH⁻). Its alkalinity is much weaker than typical strong bases like sodium hydroxide or potassium hydroxide but slightly stronger than typical weak bases like aqueous ammonia. Therefore, it is often classified as a "medium-strength base" or a "sparingly soluble strong electrolyte."

In the field of flame retardancy for synthetic materials such as plastics, rubber, and textiles, antimony trioxide (Sb₂O₃) is a ubiquitous and crucial name. While not a highly effective flame retardant on its own, its exceptional synergistic properties have made its combination with halogenated flame retardants one of the most widely used and efficient flame retardant systems, often regarded as the "classic duo" in the industry.
