What is Almina 7?
Best solution in ultra high temperature.
Alumina 7 is composed of 72% Al2O3 and 28% SiO2 continuous fiber which is not contained B2O3. Alumina 7 has excellent heat resistance, high strength, high modulus and electrical insulation ability. Alumina 7 can be expected wide range of applications.
Cloth (ALC), Tape (ALT), Sleeving (ALSV), Yarn (ALY)
