Polypropylene Copolymer (PPC)
Polypropylene copolymer (PPC) is a type of polypropylene (PP). Polypropylene is a thermoplastic polymer derived from petrochemical sources. It is a durable, lightweight, and chemically resistant material used in various industrial applications.
The properties of PPC can vary depending on the type and proportion of the monomers it contains, as well as its molecular structure. This type of polymer is particularly used in specific industrial applications because, in some cases, it can offer better mechanical properties, chemical resistance, or processability than standard polypropylene.
SPECIFICATIONS
Chemical Structure
Polypropylene copolymer (PPC) is a type of thermoplastic polymer derived from petrochemical sources. It is formed by combining different structural versions of a monomer called propylene. This combination imparts specific mechanical and chemical properties to the polymer.
Physical Structure
The physical appearance of polypropylene copolymer (PPC) typically ranges from white to transparent. However, depending on the specific formulation, processing method, and additives used, the color and transparency can vary. It usually exhibits a hard, glossy, and smooth surface.
Melting Point
The melting point of PPC can vary approximately between 130 to 171 degrees Celsius. This depends on the specific formulation of the PPC, the production process, and the monomers used.
Density
The density of PPC typically ranges between 0.90 to 0.91 g/cm³. This indicates that polypropylene is a lightweight material, meaning it has less mass per unit volume compared to other materials of the same volume.
Mechanical Properties
PPC can have high impact resistance and tensile strength, which contributes to its durability in various applications.
Chemical Resistance
PPC is resistant to many chemicals, allowing it to be used in various chemical environments.
Thermal Stability
PPC is a material resistant to high temperatures and can remain stable against temperature increases.
Electrical Properties
PPC has high insulation resistance, meaning the electrical resistance per unit volume is high. PPC also has a low dielectric loss factor, which helps minimize energy loss. All these properties make PPC preferable for electrical insulation applications.
Food Safety
Polypropylene copolymer (PPC) is generally considered a safe material for food contact, so it usually does not pose any hazards when in direct contact with food.
Elasticity
PPC has a certain level of flexibility, allowing it to be used in various applications and molded into different shapes.
Transparency
It is naturally transparent and has an optically clear appearance.
PRODUCTION
PRODUCTION STAGES
In the initial stage, the basic material, propylene monomer, is prepared. This is accomplished through petrochemical processes. Propylene is derived from propane gas. Propylene monomers are then subjected to polymerization reactions to initiate the formation of polypropylene chains. This process is facilitated with the aid of catalysts, typically metal oxide catalysts. Polymerization reactions are conducted under high temperature and pressure conditions.
Following the reaction, the product undergoes processing for stabilization. This involves the removal of by-products resulting from the reaction and enhances the quality of the product. Various additives are incorporated into polypropylene according to desired properties. This is done to adjust characteristics such as color, flexibility, and durability of the material.
Polypropylene is formulated to a state where it can be shaped while in a molten state. This is achieved through processes such as extrusion or injection molding. The shaped polypropylene products are then cooled and, if necessary, cut to specific dimensions.
