Nano Calcium Carbonate for Photovoltaic Glue - High-Quality China Suppliers & Factory Production
Product Description
Heat-Resistant & Stable Structure
USEEN's nano calcium carbonate features a complete cubic crystal structure, nanoscale particle size, and high specific surface area. Through precise surface treatment with heat-resistant activators and coupling agents, it achieves high compatibility and uniform dispersion in silicone resin systems. This structural design and heat-resistant surface treatment technology provide the material basis for photovoltaic adhesives to maintain stable performance in extreme temperature environments.
Extreme Temperature Resilience
This product achieves a balanced combination of high thixotropy, low viscosity, and high extrudability in silicone photovoltaic adhesive systems, significantly enhancing the tensile strength, elongation at break, and long-term heat resistance of the adhesive. Its stable performance without cracking, powdering, or yellowing across a wide temperature range of -45℃ to 350℃, coupled with its ability to maintain strong adhesive strength after UV aging irradiation, ensures ultra-long-term weather resistance and reliability for photovoltaic modules in harsh outdoor environments.
Precise & Durable Sealing
USEEN nano calcium carbonate, when used in silicone-based photovoltaic adhesive systems, enables simultaneous optimization of high thixotropy, low viscosity, and high extrudability, improving dispensing efficiency and ensuring precise and controllable sealing morphology. While meeting the stringent weather resistance requirements of photovoltaic encapsulation adhesives, it extends the lifespan of solar modules through a nano-reinforcement mechanism.
