Common inorganic fillers such as common talc, calcium carbonate, etc., because of its refractive index and the vast majority of the resin has a large difference, so after filling, for the finished product of the light transmittance has a greater impact, so the early transparent, translucent plastics or coatings are less or no filler, resulting in a high overall cost, so manufacturers are also constantly looking for ways to reduce costs.

Adhesives, a pivotal cornerstone of industry, are used in a wide range of key areas such as construction, automotive manufacturing, electronics and packaging, demonstrating their irreplaceable breadth and importance. In this series of applications, powder as the key additive of adhesives, like the magic powder in the hands of a magician, plays a pivotal role, adding infinite possibilities for the performance of adhesives. The purpose of this paper is to analyze the multiple applications of powders in adhesives and their core values.

Talc is one of the most widely used inorganic powders in plastic products. Talcum powder in plastic products is characterized by certain properties that can significantly improve the plastic products, therefore, the choice of talcum powder should also have the following requirements for talcum powder.

The main resins used in the shoe industry are PVC (polyvinyl chloride), RB (rubber), PU (polyurethane), TPR (thermoplastic rubber) and so on, and the addition of calcium powder mainly plays a role in reducing the cost and increasing the abrasion resistance of shoes. In this article, we will briefly introduce the application of inorganic filler for several common shoe sole materials, because the shoe sole filler involves more than calcium carbonate powder materials, but also some related fillers incidentally introduced for your reference.

Previously mentioned in the soft, now different industries for the increasing demand for transparent inorganic filler, transparent inorganic filler filler modified plastics, coatings and other industries, in order to meet the physical and chemical properties of the decline in the case of a small amount, but also has a good light transmittance.

Test results show that: viscosity comparison, nano-calcium > heavy calcium carbonate > low oil-absorbing activated calcium. 1, generally the finer the powder, the higher the oil-absorbing value, the higher the viscosity, by the nano-calcium particle size between 60-100nm, has an excellent thickening effect, can effectively improve the stability of the fluid; 2, at the same time, as can be seen above, low oil-absorbing active calcium viscosity rate slower than the heavy calcium carbonate, that is, in the same proportion of its viscosity is smaller, and the other by the right figure can be seen in the high proportion of low oil-absorbing active calcium in the addition of a certain amount of shear viscosity effect, similar to the rheological properties of talcum powder, with the production and construction of a friendly features; 3、At the same time, generally with the different additive ratio of the powder filler, the system viscosity will also appear different changes, the follow-up Division I will start a new share for this.
