. . . Factory direct sales, free trial samples for new customers, welcome to call us for consultation .
. . . Focus on silicone production for many years, more than 3 models to meet your needs
(3, , )Features and uses:
.Excellent fixing and potting , electrical, insulation, moisture-proof, shock-proof, thermal conductivity, flame retardant, aging resistance and other properties.
.Addition liquid silicone rubber does not use polar compounds as raw materials, no by-products are released during cross-linking, and can maintain better electrical properties under harsh conditions
3. Can be quickly vulcanized at high temperatures. Vulcanized silicone rubber has good weather resistance, heat resistance, and cold resistance at temperatures between ℃ and ℃.
.Non-toxic, odorless, non-corrosive and non-swelling.
(3, , ) Scope of use:
Suitable for potting protection, heat dissipation, waterproofing and moisture-proofing, and high voltage resistance of electronic components, power drive modules, printed circuit boards and automotive electrical appliances
Silicone rubber is currently widely used. On the premise of satisfying performance, how to reduce costs is also a task for our engineering and technical personnel. Through experiments, a comparative analysis was conducted on different amounts of silicon powder added to silica gel. The specific data are shown in the table below
Through comparative tests, its performance changes are as follows:
As the amount of silica powder increases, the hardness increases by about 10%. As the amount of silica powder increases, the elongation decreases, and the decrease is more obvious when it reaches 3 parts. The strength drops significantly after exceeding the limit. As the dosage increases, the vulcanization speed accelerates and the excess changes significantly, while scorch has little effect. The added value of silicon micropowder dosage increases, which is in line with the law.
Driver silica gel manufacturers share: If you add a basic formula, such as raw rubber, double indicate the content, powder or colloid or brand name of silica powder: variables. Then indicate the vulcanization conditions, vulcanization instrument test conditions, and add a specific gravity The change will be perfect. If you further test and use silica and microsilica together, from degree to degree, it will be perfect
If you do the variable basic experiment of silica powder, continue to use silica. Explore if you observe changes in material cost and then combine it with changes in specific gravity. If you do conventional physical properties, you can continue to make heat resistance trend charts. If you have finished making the same type of silica powder variables, you can continue to make in-depth parallel comparisons of silica powders of the same type and different specifications
(3, , ) How to use:
. Stir components B and B separately evenly,
. According to the dosage, press: B: Accurately weigh, stir thoroughly and mix (press within the usable time
The amount to be used up at one time to avoid waste, usable time < hours)
3. Move to the vacuum equipment to remove air bubbles,
. Move the rubber material with air bubbles removed at a uniform speed Pour it into the components to complete the potting operation.
It will solidify into an elastic rubber body at room temperature or under heating conditions. Heating can accelerate curing (below ℃).
(3, , ) Notes:
This product is a two-component addition liquid silicone rubber and cannot come into contact with organic matter containing,,,,,,
b,, B, plasma compounds, Contains alkynes and polyvinyl compounds. The above items will poison the catalyst, causing the glue to delay or not cure. This product has a large specific gravity and may stratify if left for a long time. Just stir it evenly: the shelf life of this product is one year.
