Ceramatest™ 500 is a glass bonded sythetic mica ceramic material designed to meet the exacting demands of technical markets. This material is a versatile and efficient electrical and thermal insulating material. Ceramatest 500 is a fully inorganic material used to bridge the performance gap between high performance plastics and structural ceramics. Ceramatest 500 glass bonded mica ceramic is a simultaneous union under high pressure and temperature of finely powdered electrical quality glass and precisely defined (natural or synthetic) mica. The resulting stone-like, dense ceramic material inherits all of the insulating advantages of both components.
Ceramatest™ is available in several machinable grades suitable for processing with standard carbide tools and water (or a water based lubricant) and in moldable grades that do not require firing or sintering after molding. As a result, the material can accommodate metal inserts during molding similar to thermoplastics. CeramaTest™ does not burn or outgas. The material is dimensionally stable at elevated temperatures
Max. Continuous Use Temperature is 930° F (500° C)
Ceramatest™ 500 is LIGHT GREY in Color
FEATURES AND BENEFITS
Advantages of Ceramates™ 500 - Mica-Filled Ceramic:
Fully inorganic, non-flammable, does not burn, outgas or carbonize.
Easier to machine than other machinable ceramics.
Can be drilled, bored or tapped with standard carbide tooling and water or a waterbased lubricant.
Exceptional dimensional stability throughout the usable temperature range for each material grade.
Molds and machines similar to plastics.
No post firing/sintering is required after molding or machining.
Can accommodate metal inserts during molding.
Impervious to moisture, oils and gasses.
Does not age and has an unlimited shelf-life.
Withstands thermal cycling.
Low thermal conductivity making Ceramatest™ an excellent thermal insulator.
Can be thick film metallized using metal inks or thin film sputtered.
High dielectric strength and low electrical loss.
High arc resistance.
Can be bonded to other Ceramatest™ pieces or other materials using epoxy, ceramic adhesive or sealing glass.
Vacuum tight inboth machined and molded forms without metal inserts.
