Corrosion-resistant PC film is a polycarbonate (PC) film product specially designed or treated to enhance its resistance to various chemical attacks. Polycarbonate itself has a certain degree of chemical resistance, and corrosion-resistant PC film through the selection of specific resin formulations, optimised production processes or surface modification treatments to further enhance its corrosion resistance in complex environments or exposure to specific chemicals. On the basis of maintaining the original excellent physical properties of polycarbonate, this type of film especially strengthens the resistance to various types of acids, alkalis, salts, solvents and other corrosive media, ensuring that the structural integrity and functional stability are maintained during long-term use.
Features
- excellent chemical resistance: corrosion-resistant PC film shows excellent resistance to most acids, alkalis, salt solutions and a variety of organic solvents, even in a certain concentration and prolonged contact with the situation, but still effectively prevent the penetration of chemical substances, dissolution or unfavourable reaction with the film, so as to avoid the decline in material performance or appearance of damage.
- high strength and toughness: inherited the inherent advantages of polycarbonate materials, corrosion-resistant PC film has a high tensile strength, bending strength and impact toughness, able to withstand mechanical stress while resisting chemical corrosion, suitable for applications that need to face both physical and chemical tests.
- good temperature resistance: can maintain stable mechanical properties and chemical stability in a wide range of temperatures (usually -60 ° C to 120 ° C), to adapt to automotive, electronic equipment and other fields of high and low temperature environmental changes that may occur.
- Excellent weatherability: Although polycarbonate itself has a certain sensitivity to ultraviolet light, but corrosion-resistant PC film is often through the addition of anti-ultraviolet stabilizers and other ways to improve its weatherability, resistance to degradation caused by ultraviolet radiation, to maintain the transparency and mechanical strength of long-term outdoor use.
- Dimensional stability and low water absorption: the film has a small water absorption and creep, which means that in a humid or chemical environment, its dimensional changes are extremely small, which is conducive to maintaining the tolerance requirements of precision parts and the stability of the overall structure.
- Self-extinguishing and flame retardant: Polycarbonate itself is self-extinguishing, and corrosion-resistant PC films may also be further enhanced on this basis by the addition of flame retardants to further enhance the fire rating and to meet application-specific safety standards.
- Transparency and optical properties: for transparent corrosion-resistant PC film, its transmittance can be as high as 90% or more, and has a good light diffusion and anti-glare properties, suitable for optical transparency and aesthetics of the higher requirements of the occasion.
Applications
With its unique combination of properties, corrosion-resistant PC film is widely used in a variety of fields, especially in those environments that have strict requirements for chemical resistance of materials:
- Automotive industry: As a material for automotive interior parts (e.g., lamp lenses, interior panels), exterior parts (e.g., body trim), electrical and electronic components (e.g., connectors, sensor housings), as well as functional parts (e.g., windshield laminates, insulation films), corrosion-resistant PC film is able to resist the erosion of a variety of corrosive liquids (e.g., coolant, brake fluids, detergents) and atmospheric pollutants to which the automobile may be exposed in the course of its operation. The corrosion-resistant PC film can resist the erosion of various corrosive liquids (such as coolant, brake fluid, cleaning agent) and atmospheric pollutants that may come into contact with during the operation of the car.
- electronics and electrical industry: in the field of electronic components packaging, circuit board protection, display screen protection, photovoltaic module packaging, etc., corrosion-resistant PC film provides reliable protection against moisture, corrosive gases or liquids, to ensure the long-term stable operation of electronic equipment.
- chemical and pharmaceutical equipment: in the chemical pipeline, tank lining, laboratory equipment, pharmaceutical equipment, transparent observation window, etc., corrosion-resistant PC film can resist all kinds of chemical reagents, solvents, and acid and alkali solution corrosion, to protect the structural integrity of the equipment, and at the same time provide clear visual monitoring.
- Construction and building materials: used in building curtain walls, greenhouse covering materials, light roofs, bathroom partitions, etc., corrosion-resistant PC film can resist weather erosion, ultraviolet radiation and detergents and other chemical substances, to maintain the appearance of the building aesthetics and structural durability.
- Food packaging and medical equipment: food safety standards in line with the corrosion-resistant PC film can be used for food contact packaging, providing good barrier properties and resistance to detergents, disinfectants and corrosion. In the medical field, it can be used for medical device housings, transparent medical device components, drug packaging, etc. It ensures the durability and safety of the material under frequent sterilisation conditions.
