Syensqo Solef® 2042 Latex
聚偏二氟乙烯 (PVDF)
Solef® 2042 Latex is an aqueous stabilized dispersion that contains approximately 25% by weight of a high molecular weight chemically modified PVDF copolymer (polyvinylidene fluoride) of medium crystallinity, that gives high adhesion to ceramics and separators in combination with low swelling, ideal for its usage in lithium batteries.
Solef® 2042 Latex is useful for applications such as water-based impregnation of separators in Li-Ion batteries and energy storage devices.
●The main properties of Solef® 2042 Latex are:
●Good adhesion to separator and to ceramics
●Low swelling in electrolyte
●Good wettability by electrolyte
●Good flexibility
●Good lamination to electrodes

| 補(bǔ)充信息 SAFETY The dry polymer in Solef® 2042 Latex is stable at temperatures up to 315°C (600°F). When subjected to temperatures above 315°C (600°F) for extended periods of time, hydrogen fluoride (HF) begins to evolve. At temperatures above 371°C (700°F), HF evolution becomes rapid. Thermal decomposition of the dry polymer in Solef® 2042 Latex can occur in melt processing operations as a result of excessive temperatures or in coating applications should the solvents be ignited, leading to fire. Thermal decomposition will generate HF, which is corrosive and causes burns on contact. It has an American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV-TWA) of 3 ppm (2.5 mg/m3). In case of fire, use NIOSH approved self-contained breathing apparatus and skin protection to protect against volatile decomposition products such as HF and traces of toxic fluorocarbons. In the event of thermal decomposition during melt processing operations, turn off the heat and evacuate the area until the area is cleared of HF. The dry polymer in Solef® 2042 Latex can be disposed of in an approved landfill. It should not be incinerated unless provision is made for absorption of HF. A Safety Data Sheet for Solef® 2042 Latex is available from Syensqo. SHELF LIFE Although we do not warrant a shelf life period, we believe that the practical limit shelf life of the material is 12 months from the production date, provided that the recommended storage conditions are maintained and the material remains free from foreign contamination during storage time. HANDLING AND STORAGE CONDITIONS (RECOMMENDED) Solef® Latex must be stored under suitable temperature conditions to ensure prolonged stability. Temperatures lower than 10°C must be avoided to prevent irreversible settling. Also, some settling may occur on prolonged standing and/or heat exposure. It is therefore strongly recommended that the product is always kept at temperatures below 35°C. The optimum storage temperature range is 15 to 25°C. It is also advisable that the product is homogenized by gentle rolling or stirring every four weeks and prior to use. 備注 1Melting temperature of dry polymer |
