About Calcium Carbonate for Pipes and PVC products

Calcium Carbonate for Pipes & PVC products

Calcium carbonate improves the base properties of polyvinyl chloride by adding stiffness to the polymer matrix and improving impact resistance as particle sizes become smaller. Shivish Microns LLP Calcium carbonate also improves compounding performance by helping disperse various ingredients into the PVC powder blend and improves processing by making polymer flow more homogenous. The relationship between a calcium carbonates particle size and the impact strength of the finished rigid PVC part also applies to extruded pipe and injection-molded fittings. The object is to produce an acceptable part at the lowest possible cost. This is achieved by minimizing the level of ingredients that add cost to the PVC formulation, such as impact modifier. The ideal is to eliminate the use of impact modifier. This can be achieved in larger diameter pipes using a formulation containing a 2-3 micron Shivish Microns LLP calcium carbonate. The impact specification is usually more difficult to meet in a small diameter pipe, thus a finer calcium carbonate must be usedusually in the range of 1-2 microns. In modern life, we take the long-term performance benefits of PVC pipe for granted. PVC pipe functions without corrosion or leaking and repairs are simple to perform compared to cast iron or copper piping.Shivish Microns LLP calcium carbonates are certified for plastics piping. The size of the filler used can have a dramatic effect on the impact strength of a PVC compound. Shivish Microns LLP provide very wide range of coated calcium carbonate ane uncoated calcium carbonate which suits all PVC pipes and compounding applications

FAQ's of Calcium Carbonate for Pipes and PVC products:

Q: How does Calcium Carbonate improve the properties of PVC pipes and products?

A: Calcium Carbonate acts as a filler to enhance tensile and impact strength, improves dimensional stability, and provides a superior surface finish. Its inclusion also helps reduce production costs by replacing more expensive materials and optimizes the final product's mechanical properties.

Q: What applications is this Calcium Carbonate best suited for?

A: This grade of Calcium Carbonate is primarily used in the manufacturing of pipes and PVC products, serving as a cost-reducing filler, opacifier, and strength enhancer. Its stable nature and purity also make it suitable for various plastic formulations and extruded plastic products.

Q: When should manufacturers use Calcium Carbonate in their production process?

A: Manufacturers should incorporate Calcium Carbonate during the compounding or mixing stage of PVC or plastic processing. Adding it at this point ensures uniform distribution within the polymer matrix, maximizing its strengthening and cost-reducing benefits.

Q: Where is this Calcium Carbonate sourced and supplied from?

A: Our Calcium Carbonate is sourced, manufactured, and supplied by certified exporters, manufacturers, suppliers, and traders across India, ensuring consistent standards and reliable delivery to both domestic and international markets.

Q: What is the recommended process for handling and storing Calcium Carbonate?

A: Calcium Carbonate should be stored in tightly sealed HDPE bags (available in 25kg and 50kg sizes), kept in a dry environment to prevent moisture uptake. Avoid contact with acids, and process under normal factory conditions for best results. It remains stable for up to 24 months from the date of manufacture.

Q: How does using Calcium Carbonate benefit the cost and quality of PVC products?

A: By incorporating Calcium Carbonate, manufacturers can lower material costs while maintaining or improving product strength, surface finish, and durability. This makes production more economical without compromising on the functional and aesthetic qualities of pipes and PVC items.

Q: What particle size options are available for custom requirements?

A: The product offers a customizable particle size (D50: 5-25 microns) to suit various processing needs. Manufacturers can request specific grading to achieve optimal dispersion and quality in their PVC and plastic products.
