Flame temperature vulcanized silicone rubber-HongY...

Flame temperature vulcanized silicone rubber         Flame temperature vulcanization silicone rubber, which has excellent resistance to high and low temperature performance. In -55℃ ~ 200 ℃wide temperature range, has excellent lightfastness, weather resistance Henai ozone resistance, excellent electrical insulation, moisture-proof hydrophobicity. It has no corrosion, low viscosity, permeability is empty, can quickly deep curing. Flame retardant is prominent, the material up to UL94V - O grade. By potting products after the flame retardant, the international IEC65 standard fire test, to be able to reach the standard requirements, and no burning smoke escape.        The product of the electric performance and curing temperature is small, from room temperature to 25℃ ~ 150 ℃can obtain excellent body. The curing time is longer, the better its electrical properties. Main uses:        Flame temperature vulcanized silicone rubber used for a flame retardant requirement of electrical, electronic element encapsulating, especially suitable for integrated line output transformer of potting. Method of use: 1.Formula: adhesive material is 100 ( weight ), 103 crosslinking agent 1.5 2.Ingredients: long-term static plastic material, wherein the solid filler precipitation will be needed before using, shake. According to the formula, with good material, curing reaction begins, viscosity increased gradually until into the elastomer. 3.Vacuum exhaust bubble: mixing ingredients, can make the air into the plastic material, must will melt in vacuum machine, for deaeration 10 minutes or so, not too long time. 4.Encapsulation : the need for potting element the application of cleaning agents cleaning. And it was heated at 100 ℃ for 2 hours. After the displacement of the dryer, cooling to room temperature for. Then, the row of bubble gum material filling, until the plastic material to be element coil immersion, and in second out of vacuum machine vacuum exhaust bubble 10 minutes. 5.Curing : the product in 25℃ to 150 ℃can be vulcanized. Room temperature vulcanization takes about 24 hours, and may have a layered phenomenon, generally do not use. In practical applications, often at 100℃vulcanization, lasted about half an hour. In order to make the products better electrical performance, product after curing, the filling element and curing for 4 to 8 hours.
