The application of silicone in the photovoltaic industry
Organic silicone is the main bonding sealing and potting material in the manufacturing process of photovoltaic modules, and there is a strong demand for adhesives for solar module border sealing and solar module junction box potting in the photovoltaic field.
Silicone material is a high-performance new material, is the national key support for the development of advanced basic materials, with excellent aging resistance, excellent high and low temperature resistance, good electrical insulation, hydrophobicity, biological inertia and other excellent properties. Driven by the national "dual carbon" policy, the rapid rise of national strategic emerging industries such as the photovoltaic industry, new energy vehicles, 5G communications, UHV, and aerospace has brought new markets and development opportunities to silicone.
Organic silicone is the main bonding sealing and potting material in the manufacturing process of photovoltaic modules, and there is a strong demand for adhesives for solar module border sealing and solar module junction box potting in the photovoltaic field. In addition, the rapid development of other emerging markets such as LED drive power, 5G communications, electronic and electrical, and power equipment also continues to promote the steady growth of demand for electronic adhesives.
107 adhesive is the key material for the production of silicone sealant, and silane coupling agent is the key additive for the production of high-end silicone sealant, photovoltaic film, glass fiber, paint, plastic and other materials. The main application products of silicone in the photovoltaic industry are photovoltaic module bonding sealant and junction box potting adhesive. Sealant and potting adhesive are the main bonding and sealing materials in the manufacturing process of photovoltaic modules. They are mainly used for solar module frame, photovoltaic glass waterproof sealing and junction box waterproof potting. In the packaging of the frame, sealant is used to further seal the battery assembly and extend the service life of the battery. The junction box is connected to the battery or other equipment on the back of the component, which requires the photovoltaic adhesive to have good adhesive property. The electronic components in the junction box have higher insulation requirements, and the junction box potting adhesive can improve the heat dissipation and insulation of the junction box, and also play a role in earthquake resistance and moisture resistance.
