Vermiculite Insulating Cement by ASTM International

This standard outlines expanded or exfoliated vermiculite thermal insulation, available as dry cement or plaster, to be mixed with water, applied, and dried for use on surfaces within 100F (38C) to 1800F (982C). The product consists mainly of expanded or exfoliated vermiculite and a heat-resistant binder. Initial qualification involves testing for consistency, compressive strength, linear shrinkage, apparent thermal conductivity, and dry adhesion to steel, ensuring these meet specified requirements.

• Insulation Material: Dry cement or plaster form, mix with water, apply as plastic mass, dry in place for surfaces between 100F (38C) and 1800F (982C)
• Avoid use in combustion conditions, e.g., hot face lining of a furnace
• Inch-pound units are standard; SI units are for information only
• Safety hazards caveat: User responsible for safety, health, and environmental practices
• Manufacturer's responsibility to inform about safety issues and recommend protective measures
• Standard developed following WTO TBT Committee's standardization principles
