The effects of Vietnam Calcium Carbonate on the properties of PCL wood-plastic composites is significantly. The strength and the melt flow rate of the composites increased first and then decreased with the content of Calcium Carbonate, and up to maximum while the content of CaCO3 is 30%. Gaps and holes could be seen from the SEM figure in the composites when the content of CaCO3 is more than 30%. Above all, the best content of CaCO3 in the composites is 30%.
Wood plastic composites (WPCs) have become a successful commercial building material with an increasing market potential during the past years due to their recyclability, low density, low cost, low maintenance, good mechanical properties, and biological performance. WPCs consist of varying contents of wood, plastics and additives, and are processed by thermoplastic shaping techniques suchas extrusion, injection molding, and compression molding. WPCs have been used in increasinglywidespread applications, including siding, roofing, windows, door frames, and outdoor furnitureindustry (PDF) The effects of CaCO3 on the properties of PCL wood-plastic composites.
Vietnam Calcium Carbonate particles have been widely compounded into polymer matrices to enhance the impacttoughness of polymers. Researchers usually agree that the impact strength depends on the particledispersion such as particle shape, particle size and aspect ratio, owing to their great impact on theparticle–matrix interaction and the overall structure
A small amount of Vietnam Calcium Carbonate could enhance the strength of the PCL composites. The strength is up tomaximum when the content is 30%. The matrix will have fault, and the strength of the compositedecrease when the content of CaCO3 is more than 30%.
A small amount of Vietnam Calcium Carbonate could reduce the frictional resistance of the chain of PCL, andenhance the melt flow rate and the processing performance. Excessive content of CaCO3 reduce theactivity space of molecular chain and the melt flow rate, which demonstrate that the optimal content ofCaCO3 is 30%
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).
