Sheffield Refractories Limited Jonram phosphate bonded plastic mouldable and ramming materials are designed to be installed using ramming equipment, some of the softer products can be parged and hand formed. Useful where flexibility is required and for patching existing linings. These products have higher strength than standard mouldables and are made using less clay giving better high temperature performance. Pneumatic ramming equipment, supervisors and installers can be hired to install these products. There are many products to chose from and our sales and technical staff will offer advice on materials for different applications
