As solar manufacturers shift toward double-glass modules, silicone sealants have emerged as critical for ensuring 25-year lifespans. Leading Chinese adhesive firm *ChemStrong* recently launched a next-gen optically clear silicone rubber, proven in extreme environments (Xinjiang/Qinghai) to reduce edge yellowing by 40%. The modified silicone resin base withstands UV radiation and temperature swings (-50°C to 150°C), effectively blocking moisture penetration between glass and solar cells. Industry analysts forecast silicone sealant demand in photovoltaics will exceed 500,000 tons by 2025, driving down clean energy costs. Products-IOTA
