Application:
SF-49A: This product is major for molding products requiring high tensile strength.
SF-48A: It is suitable for pressing large billet, which can be processed into turning film, turning board and other products. Due to its low metal ion precipitation performance, it can be widely used in semiconductor, 5G, medical and other high-end fields.
SF-46A: Making the film, color film and as raw material to produce free flow resin.
SF-461: This product is suitable for sealing gaskets, high-end pumps and valve linings with high creep resistance requirements, and has good mechanical and electrical properties, good weld-ability and low metal ion precipitation performance. It is widely used in semiconductor, 5G and other high-end fields. MIT Flexural Life (0.4 mm sheet,23℃) ,104 cycle ≥200. Compression Set (23℃, 14MPa, 24h) % ≤5.0.
SF-462: The product is suitable for diaphragm sheet, bellows and other products with high bending resistance requirements, and has good mechanical and electrical properties, good weld-ability, low metal ion precipitation performance, widely used in semiconductor, 5G and other high-end fields. MIT Flexural Life (0.4 mm sheet,23℃) ,104 cycle ≥600. Compression Set (23℃, 14MPa, 24h) % ≤6.0.
Packaging, Storage and Transportation:
1. The product is packed in two layers of plastic bags in a hard bucket with a net content of 20kg per barrel.
2. The products shall be transported as non-dangerous chemical. During transportation, prevent from humidity, intense vibration and package damage.
3. Products should be stored in a clean, cool and dry warehouse to prevent the mixing of dust, moisture and other impurities.
