Whip Mix Hard Rock Ivory ISO Type 5 Dental Stone 33 lb / 15 kg (330003)

Whip Mix Hard Rock Ivory is an ISO Type 5 dental stone supplied in a 33 lb (15 kg) container. The material is compatible with all impression types, though its high setting expansion of 0.28% makes it particularly well suited for use with polyvinyl or polyether materials. It features a creamy, thixotropic consistency that flows readily under vibration while remaining stackable, and its 6–8 minute working time accommodates multiple pours from a single mix. The set stone delivers a smooth, non-brittle surface that trims without chipping, with a wet compressive strength of 7,000 psi at one hour and a dry compressive strength of 15,000 psi (104 MPa) at 48 hours.
