ALTIFIL™ products consist of a natural combination of pyrophyllite and quartz. They have permanent expansion, excellent reheat stability, low hot load deformation, low reversible thermal expansion, low thermal conductivity, low shrinkage, and high resistance to molten ingress. Because of its stable nature and physical properties, pyrophyllite is employed in mold release and parting agents in foundry and structural clay.
Applications include:
- Foundry coating for mold release
- Foundry filters
- Foundry washes
