PVC Resin is a thermoplastic polymer that is widely used in the production of various plastic products, such as pipes, fittings, vinyl flooring, electrical cables, and many more. PVC stands for polyvinyl chloride, which is a synthetic polymer made from vinyl chloride monomer.
PVC Resin is a versatile material that can be formulated to meet specific application requirements, and it offers a range of desirable properties, including high strength, durability, chemical resistance, and low flammability. Additionally, PVC Resin is relatively easy to process and can be molded or extruded into various shapes and sizes. However, PVC Resin also has some drawbacks, such as its susceptibility to thermal degradation, its production process that involves the release of toxic byproducts, and its non-biodegradability, which can contribute to environmental issues if not properly managed. As such, the use of PVC Resin is often subject to regulations and guidelines aimed at minimizing its environmental impact.
Processing Aid is a chemical substance that is added to plastic raw materials during the production process to facilitate processing or improve the performance of plastic products. These chemical substances can be a blend of organic or inorganic materials.
Processing Aid can help reduce friction between plastic materials and processing equipment, making the mixing process easier and resulting in more consistent plastic products. In addition, Processing Aid can improve the strength and stiffness of products, increase water absorption, improve weldability, and enhance the overall quality of plastic products. The selection and use of Processing Aid depend on the specific application requirements of the final products, and the appropriate Processing Aid must be carefully chosen to ensure compatibility with the base plastic material and the processing conditions.
PVC stabilizer is a chemical additive that is added to polyvinyl chloride (PVC) resin during the production process to improve the stability and durability of PVC products. PVC is a thermoplastic polymer widely used in the production of various plastic products, such as pipes, profiles, cables, flooring, and many more. However, PVC can be prone to degradation due to exposure to heat, light, and oxygen, which can cause discoloration, brittleness, and loss of mechanical properties.
PVC stabilizer helps prevent the degradation of PVC by inhibiting or slowing down the oxidation process. It works by scavenging free radicals formed during the degradation process and preventing them from reacting with PVC chains. PVC stabilizers can also enhance the thermal stability of PVC by improving the melting and processing properties of the resin, thus reducing the risk of degradation during processing.
There are various types of PVC stabilizers available, including lead-based, calcium-based, and organotin-based stabilizers, each with its unique advantages and limitations. The selection of the appropriate PVC stabilizer depends on the specific application requirements of the final product and the applicable regulatory requirements.
An impact modifier is a chemical additive that is added to plastic materials to improve their toughness and impact resistance. Plastic materials, such as PVC, polystyrene, and polyethylene, can be brittle and prone to cracking or breaking upon impact, especially at low temperatures.
There are various types of impact modifiers available, including rubber-based, acrylic-based, and styrene-based modifiers, each with its unique advantages and limitations. The selection of the appropriate impact modifier depends on the specific application requirements of the final product, such as the required level of toughness, impact strength, and processing conditions.
Lubricants are divided into two areas, internal and external lubricants. The transition between external and internal lubricating effect is fluid, however, – internal lubricants often also have a certain external lubrication effect and vice versa. Lubricants having both effects are therefore called “combined lubricants”. Internal lubricants reduce the frictional forces occurring between the PVC molecule chains, thus reducing melt viscosity. They are polar and thus are highly compatible with PVC. They help achieve excellent transparency.
even at high dosages and do not tend to exudate, which helps optimizing welding, gluing, and printing properties of the final product. External lubricants reduce the adhesion between PVC and metal surfaces. They are mostly non-polar such as paraffin and polyethylene waxes. The external lubrication effect is largely determined by the length of the hydrocarbon chain, its branching and its functional group. At high dosages they can lead to cloudiness and exudation.
Plasticizer raw materials are chemical additives that are added to plastic resins during the production process to improve their flexibility, workability, and durability. Plasticizers work by reducing the glass transition temperature of the polymer, making it softer and more pliable. This process is called plasticization, and it allows plastic materials to be molded or shaped into different forms and sizes.
The selection of the appropriate plasticizer depends on the specific application requirements of the final product, such as the desired level of flexibility, temperature range, and durability. It is essential to choose the right plasticizer and follow the recommended safety and regulatory guidelines to ensure the best performance and safety of the final product.
