Rigid PVC foam is in growing demand for use in various applications as a replacement for solid vinyl or wood. The market for PVC foam can be divided in three main categories: sheet, profile, and foam core pipe. PVC foam properties, such as tensile and flexural strength, modulus, impact resistance, and water adsorption, depend on two factors: foam density, and cell structure. Certain ingredients of the PVC formulation, such as the as the type of stabilizer, type and level of the acrylic processing aid, and processing conditions, play a role in determining foam density. The effect of the Vietnam Calcium Carbonate particle size has been studied in rigid PVC formulations; however, we have not found any published references on the subject in foam formulations.
Vietnam Calcium carbonate is the predominant filler used in polyvinyl chloride compounding. Selection of fillers, as in the case with other compounding ingredients, involves consideration of available types and their effects on processing, product properties, and economics.
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).
