August 13, 2024 – PVC Pipe and Fitting Manufacturers Seek Cost-Cutting Solutions with Modified Calcium Carbonate
In the pursuit of reducing raw material costs, PVC pipe and fitting manufacturers have turned their attention to heavy calcium carbonate as a cost-effective filler. However, given the stringent demands on mechanical strength, appearance, and density of PVC products, the efficient utilization of this filler has become a focal point of current research.
Recently, a novel modified calcium carbonate filling material has sparked significant discussion within the industry. Produced through wet grinding of heavy calcium carbonate and utilizing in-situ polymerization modification techniques, this material offers a remarkable enhancement in the mechanical properties and aesthetic quality of PVC fittings. This innovation presents manufacturers with an economical and high-performance filling option.
According to AsiaMB, the modification process involves various methods, including direct modification with polyvinyl acetate, in-situ polymerization modification with polyvinyl acetate, and stearic acid modification. These techniques effectively improve the compatibility between calcium carbonate and PVC resin, thereby elevating the overall product performance. Notably, calcium carbonate modified via in-situ polymerization with polyvinyl acetate exhibits superior mechanical properties in PVC materials. This enhancement is attributed to polyvinyl acetate facilitating better compatibility between calcium carbonate and PVC resin, while also introducing an elastomeric component to the material.
Industry experts believe that this modified calcium carbonate not only cuts down production costs for PVC fittings but also elevates product performance. This development is expected to provide manufacturers with a significant competitive advantage in the fierce market competition. Moreover, this research injects new vitality into the sustained growth of the PVC pipe and fitting industry.
