Product Overview
Plastic refractories are stiff, putty-like mixes supplied ready to install, rammed or pneumatically gunned into place and then dried in service. Phosphate-bonded high-alumina grades develop strength rapidly on heating and give excellent volume stability around complex shapes.

Frequently Asked Questions
A plastic refractory is a stiff, putty-like refractory mix supplied ready to install, you ram or gun it into place and dry it in service, rather than casting it. Phosphate-bonded high-alumina grades develop strength quickly on heating and hold their shape around complex geometry, making them ideal for burner blocks, patching and linings around tubes.
