Synthetic leather, also called artificial leather or coated textile, is becoming more popular as a substitute for natural leather in a variety of applications thanks to its low cost and its similar look and durability to authentic leather. The coating is increasingly becoming an important way of adding value to textiles. It aims to develop the functional properties of textiles, improve certain characteristics, and guarantee that fabrics meet parameters of performance that will not be achievable from uncoated and leathered fabrics.

Vietnam Calcium carbonate is one of the most widely used fillers for the PVC leather industry, conventionally CaCO3 has been employed to minimize its cost and enhance its melting viscosity, and mildly increase the modulus of the final product due to its small surface area and undesirable geometrical aspects. However, some mechanical properties remained constant or, in some circumstances, declined. Particle shape and size and filler quantity have recently been reported to have a significant effect on PVC materials filled with calcium carbonate. Rigorous studies have shown the effect of Vietnam calcium carbonate on the mechanical behavior of PVC materials.

Also, Vietnam CaCO3 particle size and content have a significant effect on the morphological structure, the thermal characteristics, and the physical properties of the PVC products.

The effects of particle size and content of Vietnam CaCO3 filler on the thermal properties of the PVC foamed layer used for synthetic leather were investigated, and we have demonstrated that adding CaCO3 can ameliorate the thermal stability of the PVC foamed layer. Therefore, the melting point and the onset decomposition temperatures of the filled foamed layer increase compared with the unfilled one. Many authors attributed these findings to CaCO3 ’s superior ability to trap HCl gas produced during PVC decomposition. Moreover, we observed that the most important positive impact on thermal stability was detected when using a smaller particle size, which has contributed to its larger surface area that can help to consume much more HCl gases, according to several researchers.

We offers a wide range of Vietnam Calcium Carbonate of different particle size assuring that our different clients will receive suitable quality material with cost-efficiency. We have the purest and brightest source of calcium carbonate and exploit the high standard of sustainability with uncoated and coated Calcium Carbonate (Stearic acid coating Calcite Powder). Raw materials are chosen carefully and the production process is conducted in ISO standard factories to ensure the most consistent quality for end-users.

Uncoated calcium carbonate is natural calcium carbonate obtained from high purity Vietnam lime stone. It is used in many industries as filler to reduce production cost. We can provide a wide range of particle size from 5 to 450 microns.

Coated calcium carbonate is made from uncoated calcium carbonate with 1% stearic acid. It is used for replacing some expensive polymers and additives to reduce production cost with particle size ranging from 5 to 45 microns.

We offers a wide range of calcium carbonate of various particle size, Uncoated and Coated Calcium Carbonate (Stearic acid coating Calcite Powder).
