Product Description
Grafit yang Dapat Diperluas
Grafit yang dapat diperluas adalah senyawa interkalasi grafit sintetis yang mengembang atau mengelupas saat dipanaskan. Setelah dipanaskan, ia menghasilkan peningkatan volume hingga 400 kali lipat, penurunan kepadatan curah, dan peningkatan luas permukaan sekitar 10 kali lipat. Kemudian dikompresi menjadi lembaran fleksibel yang sangat kohesif.
Aplikasi utama lainnya adalah sebagai penahan api. Akibat panas api, grafit mengembang dan menciptakan lapisan intumescent pada permukaan material. Hal ini menghambat penyebaran api dan meminimalkan salah satu efek paling berbahaya dari pembakaran: penciptaan gas dan asap beracun.
Manfaat grafit yang dapat diperluas sebagai penahan api:
- Membentuk lapisan intumescence dengan Perisai Radiasi Termal, dengan Difusi Panas yang unggul.
- Menghentikan atau memperlambat penyebaran api dan gas beracun.
- Mudah diaplikasikan, hemat biaya, kinerja memuaskan dengan tingkat penambahan yang rendah.
- Aditif penahan api non-toksik, non-halogenasi.
- pH permukaan netral membuatnya kompatibel dengan sistem katalis apa pun.

This is our first order of expandable graphite for R&D purposes. The product arrived well-packaged and dry. The technical data sheet provided was accurate. We tested the expansion ratio under high heat, and it matched the manufacturer's claim closely. The flake size distribution was good. Customer service was responsive to our pre-sale inquiries. Will order again for our larger batch production.
