PVC plastic, or Polyvinyl Chloride, is formed through a process called polymerization. It involves the reaction of vinyl chloride monomers, under the influence of initiating substances such as peroxides. When these monomers come into contact with the initiators in the presence of heat and pressure, they link together in a chain-like structure, forming the PVC polymer. This reaction can be finely controlled to obtain PVC with desired properties by adjusting the formulation and polymerization conditions. After polymerization, the PVC is stabilized to prevent decomposition, mixed with additives for flexibility, color, or weather resistance, and finally processed into its final form through methods like extrusion, molding, or calendaring.
The ratio of catalyst (often MEKP, Methyl Ethyl Ketone Peroxide) to resin for lamination can vary depending on factors such as the type of resin, temperature, desired cure time, and manufacturer's recommendations. Generally, the ratio falls within the range of 1% to 3% by weight of the resin. For example, when using polyester resin, a common ratio is 1.5% to 2%. It's vital to accurately measure this ratio to ensure proper curing and to avoid issues like under or over-curing, which can affect the structural integrity and performance of the laminate. Also, always refer to the product datasheet for the specific resin system you are using, as it will provide the most accurate and safe mixing ratios and conditions.
