This research primarily focuses on the feasibility of substituting imported calcium carbonate fillers with locally available materials for PVC pipe applications.
Calcium carbonate fillers have ideal properties for many polymer applications and the world consumption is over ten million tonnes annually. Both natural (ground (natural) calcium carbonates, GCC) and synthetic forms are in use and can be derived from abundant and widely occurring natural deposits.
The test results showed that with the increase of calcium carbonate dosage, the tensile properties of PVC pipe gradually decreased, and the impact strength and bending strength increased. ... Li Na et al. prepared PVC/calcium carbonate/talc composites by melt blending process, and investigated the effects of talc and calcium …
Calcium Carbonate for PVC Pipe Industry. Description: Precipitated Calcium Carbonate ( PCC ) is an innovative product derived from lime stone, which has many industrial applications. PCC is made by hydrating high- calcium quick lime and then reacting the resulting lime slurry with carbon dioxide.
A standard twin screw, tin-stabilized high fill (30 phr calcium carbonate) PVC pipe recipe was run for 16,000 cycles. To minimize the effects of PVC thermal degradation, 10 runs of 20 minutes each was required with 80 rpm rotor speed for each data point.
Columbia River Carbonates, located in Woodland, Washington, USA, was established in 1985 as a supplier of high-grade ultra-fine ground calcium carbonate products and technical service for the paper, paint, plastic and other industries throughout the Northwestern United States and Western Canada.

Precipitated Calcium Carbonate ( PCC ) is an innovative product derived from lime stone, which has many industrial applications. PCC is made by hydrating high- calcium quick lime and then reacting the resulting lime slurry with carbon dioxide.
Calcium carbonate is one of the most widely utilized minerals additives in several PVC applications. Ground calcium carbonates (GCC) are used mainly as fillers, while precipitated calcium carbonates (PCC) are multi-functional additives that can function as reinforcing fillers, processing aids and impact modifiers.
This forms because calcium carbonate dissolves. The rock is limestone, which is usually composed of pure calcium carbonate. Acidic water greatly enhances the solubility of calcium carbonate, and it doesn't even need to be highly acidic.
The calcium carbonate powder as a filler can have a dramatic effect on the impact strength of a PVC compound. We provide a very wide range of calcium carbonate powder which suits all PVC pipes and compounding applications. Calcium carbonate is one of the most famous fillers in minerals, that is highly used in the plastic industry.
The negligible variance observed may stem from the pronounced effect of calcium ions and calcium carbonate on clay particles—facilitating their agglomeration and subsequent conversion into silt particles, which under the influence of calcium carbonate, further transition into sand particles.
The relationship between a calcium carbonate's particle size and the impact strength of the finished rigid PVC part also applies to extruded pipe and injection-molded fittings.
The current high global demand for high-quality paper, paint, adhesive/sealant, and plastic, filler industries cannot survive without unique and high-quality precipitated calcium carbonate (PCC). They are used as fillers, additives, and reinforcements. PCC is a key constituent of the modern paper and plastic industry. This …
Effect of Iron Content in Ground Calcium Carbonates on Accelerated Weathering Properties of Rigid PVC Pipe Compounds Lane G. Shaw and David Yu
Tensile strength properties of PVC-U, filled with precipitated and ground calcium carbonate, have been investigated.Calcium carbonate nano particles are commercially available and are claimed to give a cost effective way of increasing impact strength. Their use in impact modified PVC has improved mechanical properties.
The bicarbonate ions existed in Water 3. The carbonate ions existed in the other water samples. The calcium ions, carbonate ions, and bicarbonate ions were the sufficient conditions of the calcium carbonate formation. The concentration of these ions was very large, so there were lots of calcium carbonate crystals in these tunnel …
