Objective: To study the dissolution and hydrolysis properties of polyester sizes. Methods: By immersing polyester sizes and size films in ultrapure water and alkaline solutions, their solubility and hydrolytic characteristics were observed. Results: In ultrapure water, the dissolution time of polyester sizes and size films decreased as temperature increased, while increased water hardness led to
Key Differences Between Low Melting Point Polyester (LMP) Chip and Normal PET Chip The fundamental difference between Low Melting Point (LMP) chip and normal PET chip lies in their melting points, which is a result of distinct chemical compositions and internal structures. This leads to significant variations in properties, processing methods, and applications. Item Low
As the outermost layer protecting photovoltaic (PV) modules, the backsheet is directly exposed to harsh environmental conditions and cyclic mechanical stress. Key performance parameters—such as adhesion, UV resistance, and mechanical strength—are critical factors that determine the overall service life of the module. PV Module Backsheets The Role of the Backsheet The solar backsheet
Photovoltaics (PV) has become one of the fastest-growing renewable energy sources. As a core material for module encapsulation, demand for polyester chips for backsheets will continue to rise. In distributed generation, the trend toward lightweight modules may drive the substitution of glass with polyester-based backsheets. Performance optimization and specialization are the key development pathways for
