Whipmix Casting Ring Liner is made from a cushioning material that provides the correct water absorption, which enables the investment to control setting expansion. During burnout it chars to a black ash which crumbles easily when the mold is pushed out of the ring.

Specs:

• Cellulose
• Non asbestos

Liners should be 3mm (1/8") short of each end of the casting ring.

Item includes: 60/Pack
