Faedah gasket silikon
Terdapat berjuta -juta bahan yang tersedia untuk membina gasket, but silicone gaskets stand out because of their numerous benefits. They can be used in both indoor and outdoor settings.
Ability To Withstand High And Low Temperatures
Silicone gaskets are ideal for many industrial applications because they can withstand temperatures of up to 392 degrees Fahrenheit continuously, without degrading or wearing out. Selain itu, they can tolerate heat up to 428 degrees Fahrenheit on an intermittent basis.
In addition to being heat-resistant, silicone gaskets remain flexible even at extremely cold temperatures. They can withstand temperatures as low as -94 darjah Fahrenheit.
Excellent Insulation
Silicone gaskets are good insulators of electricity. By combining silicone with nickel-graphite or silver-plated aluminum particles, they can also filter electromagnetic interference (EMI) due to their conductive qualities. Ini amat penting untuk peranti elektrik.
Silikon digunakan secara meluas dalam penebat voltan tinggi dan komponen elektrik lain. Mereka boleh disambungkan silang oleh proses kimia yang berbeza, menjadikan mereka tidak reaktif pada suhu tinggi. Sektor elektrik sangat bergantung pada bahan-bahan yang tidak reaktif ini.
Apabila pelepasan elektromagnet adalah masalah, silikon boleh digabungkan dengan karbon separa konduktif untuk menyediakan perlindungan pelepasan elektromagnet.
Sangat tahan lama
Gasket silikon sangat tahan lama, kerana mereka tahan radiasi UV, ozon, dan keadaan cuaca yang keras. Ini menjadikan mereka sesuai untuk kegunaan luaran. Selain itu, panjang umur mereka menjadikan mereka pilihan yang murah. Mereka adalah bahan yang boleh dipercayai dan stabil yang boleh digunakan untuk jangka masa yang panjang tanpa mempamerkan pakaian, Dan mereka tidak memerlukan banyak penyelenggaraan selepas pemasangan.
FDA diluluskan
Gasket silikon diluluskan oleh FDA, menjadikan mereka sesuai untuk digunakan dalam peralatan perubatan, instrumen penjagaan kesihatan, dan loji pemprosesan makanan. Mereka juga boleh dicampur dengan sebatian yang diluluskan oleh FDA yang lain untuk menghasilkan kekuatan air mata yang tinggi.
Berbeza dengan gasket asbestos, Gasket silikon secara medis tidak aktif, bermaksud mereka tidak beracun dan tidak membahayakan manusia. Ciri -ciri ini menjadikan gasket silikon penting untuk industri seperti penjagaan kesihatan, pemprosesan makanan, Diagnostik Perubatan, dan farmaseutikal.
Retardant api
Gasket silikon mempunyai tahap mudah terbakar yang rendah, yang menjadikan mereka sesuai untuk perniagaan yang menjana haba yang ketara. Mereka boleh bekerja dalam peralatan telekomunikasi dan sistem transit awam.

Gasket silikon mengekalkan meterai kedap air, memastikan bahawa perniagaan anda tetap kering dan bebas kelembapan, Walaupun dalam persekitaran yang mencabar.
Jenis gasket
Gasket silikon boleh dikelaskan dengan pelbagai cara. Contohnya, Gasket silikon pepejal dan gasket silikon span berasingan kerana mereka mempunyai struktur molekul yang berbeza. Kekerasan atau durometer juga membezakan pengedap silikon. Foam silicone gaskets may be soft like sponge silicone gaskets, but foam silicones are separate because they include different components and employ other curing procedures. Interstate die cuts all of these silicone gasket kinds.
Solid Silicone Gaskets
Solid silicone gaskets are comprised of solid rubber components with a tightly-packed molecular structure.
- They have lower durometers (hardness) and compression rates than sponge silicones
- Not all solid silicones are “soft”
- Lower-durometer solid silicones provide robust environmental sealing with low closure force
- Solid silicone gaskets with mid-range durometers require increased closing force
Sponge Silicone Gaskets
Sponge silicone gaskets are comprised of sponge-like silicone compounds that provide cushioning and padding. Interstate die cuts both primary types of sponge silicone materials: open-cell and closed-cell.
- Open-cell silicone gaskets have linked pockets that unless the gasket is squeezed, enable water, bahan kimia, and air to flow
- Closed-cell silicone gaskets are filled with nitrogen gas to block the passage of these compounds at low pressures
Foam Silicone Gaskets
Foam silicone gaskets are constructed of soft, sederhana, firm, or extra-firm silicone grades for varied quantities of compressibility.
- They have a lower compression set than sponge silicone gaskets
- Provide greater flame resistance
The die cuts the three primary forms of foam silicone materials: open-cell, closed-cell, and silicone rubber which contains both open and closed cells. Like solid silicones and sponge silicones, foam silicones have diverse uses.
Injection Molded Silicone Gaskets
Molded silicone seals with round or bespoke cross-sections are commonly required for high wash down (IP66 or NEMA 4) or water submersion requirements. Getah silikon cecair (LSR) permits very tiny cross sections, down to .030″, to be molded in durometers from 10 kepada 70 Pantai A. Using injection molded liquid silicone rubber, separating line flash may be eliminated to guarantee sealing integrity.

Silicone Gaskets FAQs
What are silicone gaskets used for?
In the building sector, doors and HVAC systems are sealed with silicone gaskets. They are utilized in industrial oven seals and equipment for food preparation. They are utilized for medical and healthcare devices in the sector.
Does silicone make a good gasket?
Silicone is a good choice for gaskets because it makes a tight seal and repels water. Lebih-lebih lagi, its capacity to endure temperature fluctuations make it preferable to many other forms of rubber.
What are the disadvantages of silicone gaskets?
One of the biggest drawbacks of silicone rubber is its weak rip strength. This can be enhanced with the addition of additional chemicals, but it doesn't inherently give strength or abrasion resistance, therefore the application needs to be carefully analyzed for the suitability of silicone as a solution.
Is it OK to use silicone on rubber gasket?
Depending on what it's for but ultimately, Ya. Silicone is what rubber is composed of. Silicone is used to “fill the gaps” depending on what gasket you refer to and if it is supposed to be removed later on.
How Do Silicone Gaskets Compare to Rubber Gaskets?
While rubber gaskets come from rubber trees, silicone gaskets are man-made. In certain situations, silicone gaskets can perform better and be more efficient. Contohnya, they are preferable when dealing with extremely high temperatures.
Natural rubber can effectively perform within a range of -58 kepada 176 darjah Fahrenheit, whereas silicone can endure severe temperatures from -58 darjah hingga 446 darjah. Natural rubber begins to wear out around 176 degrees and melts at 248 darjah.
Rubber cannot be used with ozone, asid kuat, lemak, minyak, and grease. Sebaliknya, silicone can be utilized with these materials. Silicone gaskets are suitable in harsh weather conditions and for outdoor use with UV exposure.
Do you put silicone on both sides of a gasket?
Unless a primer is necessary, you should apply the sealant to the prepared surface. Apply an equal coat to all sides of the gasket.
