Calcium Carbonate for Pipes and PVC products

उत्पाद वर्णन

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
