Common types of engineering plastics:
Polyamide (Nylon) : such as PA6, PA66, with good mechanical properties and wear resistance.
Polycarbonate (PC) : With high transparency and impact strength, it is often used in transparent parts.
Polyformaldehyde (POM) : Excellent wear resistance and mechanical strength.
Polyphenylene sulfide (PPS) : high temperature and chemical resistance.
Polyimide (PI) : has extremely high heat resistance and electrical insulation.
Polyester (PET, PETG) : has good transparency and impact resistance.
Polysulfone (PSU) : high temperature and chemical resistance.
Engineering plastics have a variety of important applications in the photovoltaic field:
Junction box: Engineering plastics have good insulation properties and weather resistance, and can be used to manufacture junction boxes for photovoltaic modules, protecting the electrical connection part from environmental effects.
Frame: Some engineering plastic materials can be used to make the frame of the photovoltaic module, providing a certain structural support and protection.
Connectors: Engineering plastics with excellent mechanical and electrical properties can be used to manufacture connectors in photovoltaic systems, ensuring the reliability and stability of the connection.
Packaging materials: Some engineering plastics can be used as packaging materials for photovoltaic modules after special treatment to improve the durability and protective performance of the components.
1. Nylon(PA)
Basf Ultramid® PA is one of the most reliable flame retardant materials for manufacturing photovoltaic connector products, which can guarantee safe electrical connections for photovoltaic power generation systems for more than 25 years.
In the photovoltaic field, PA materials are mainly used in connectors.
2. Polyimide (PI)
Polyimide is a high performance engineering plastic with excellent mechanical properties, heat resistance, chemical stability and corrosion resistance.
In the photovoltaic field, PI materials are mainly used in the backplane and frame of solar panels.
Due to the high temperature resistance and ultraviolet resistance of PI material, it can effectively protect solar panels from the external environment, improve their service life and photoelectric conversion efficiency.
3. Polyether ether ketone (PEEK)
Polyether ether ketone is a kind of high temperature and high strength engineering plastic with excellent physical properties and chemical stability.
In the photovoltaic field, PEEK materials are mainly used in the transparent conductive film, packaging tape and junction box of solar panels.
Due to the high temperature resistance, corrosion resistance and tensile strength of PEEK material, it can effectively protect solar panels from the influence of the external environment, while ensuring the stability and reliability of its electrical performance.
4. Polycarbonate (PC)
Polycarbonate is a kind of engineering plastic with excellent comprehensive properties, which is widely used in automotive, electronics, construction and other fields.
In the field of photovoltaic, PC materials are mainly used in the covering materials and borders of solar panels.
Due to the high light transmission, weather resistance and impact resistance of PC materials, the lighting efficiency and mechanical strength of solar panels can be effectively improved.
5. Polyphenylene sulfide (PPS)
Polyphenylene sulfide is a kind of high temperature and high pressure engineering plastic, with excellent chemical corrosion resistance and mechanical properties.
In the photovoltaic field, PPS materials are mainly used in the packaging materials and junction boxes of solar panels.
Due to the high temperature resistance, corrosion resistance and aging resistance of PPS material, it can effectively protect solar panels from the influence of the external environment, while ensuring the stability and reliability of its electrical performance.
6. Polytetrafluoroethylene (PTFE)
Polytetrafluoroethylene (PTFE) is a kind of engineering plastic with strong chemical resistance, which is widely used in chemical industry, medicine, electronics and other fields.
In the photovoltaic field, PTFE materials are mainly used in the packaging materials and coatings of solar panels.
Due to the high temperature resistance, low friction coefficient and non-viscosity of PTFE material, it can effectively prevent the occurrence of short circuit and leakage phenomenon, and improve the sealing and waterproof performance of solar panels.
7. Polyvinylidene fluoride (PVDF)
Polyvinylidene fluoride has excellent properties such as anti-aging, chemical resistance, weather resistance and UV radiation resistance.
In the photovoltaic field, PTFE materials are mainly used in the packaging materials and flexible films of solar panel.
8. Polystyrene (PS)
PS is a transparent and rigid plastic, which is often used to make packaging materials for solar panels. It has good optical properties and weather resistance, but poor temperature resistance and impact resistance.
In the field of photovoltaic, PS materials are mainly used in guides, auxiliary components and so on.
