NORPLAST^™ Plastic Mixes

NORPLAST™ ready-to-use plastic refractory mixes are the first choice for many applications, including spout, top, ladle or launder. They can be utilized for rapid cold or hot repair as well as full supporting refractory lining.

NORPLAST™ plastic products can be applied by hand using a trowel (for example, for quick repair of cracks or wear zones) or using a specialized tool such as a pneumatic hammer.

What can plastic products be used for?

NORPLAST^™ plastic products can be used to repair cracks that occur during melting in the furnace aggregate.

Plastic mixes are often used to shape the spout or topping of furnaces because they are easy to apply and will remain in place, even if a relatively thick layer is applied. NORPLAST^™ A 90 PF is popular with a wide range of customers. Its optimized raw materials ensure a product that is soft and easy to apply, ensuring extended shelf life, time savings and reduced downtime.

What type of plastic mass should be used in iron melting applications that already employ a mullite-based refractory lining in the furnace and transport ladle?

The mullite-based NORPLAST^™ M 70 PF helps to preserve the homogeneity of the original lining while being easy to apply and offering an excellent shelf life.
