Details
Extruded batts can be split into ten sub-categories as follows: Extra Large Batt, Extra Thin Batt, Plain Batt,Perforated Batt, Grooved Batt,Trapezoid Batt, Recessed Batt, Full Disc, Half Disc and Special Batt.
Features:
(1) High melting point;
(2) Excellent creep resistance;
(3) Low coefficient of thermal expansion and excellent thermal shock resistance;
(4) Excellent corrosion resistance;
(5) High shear modulus.
Applications：
Widely used in electronics, ceramics, abrasives, magnetic materials, glassware, rare earth chemical production and other industries.
