High Quality Plastic Refractory

Excellent Plasticity

Easy to Construct

High Refractoriness

Good Abrasion-resistance

High Density

As an amorphous refractory material, Plastic Refractory is made up of refractory granular and powdery materials (70% to 80%), plastic clay as blinders, and appropriate plasticizer. Plastic clay is an important component of plastic refractory, which has a great influence on the bonding strength, plasticity, volume stability and refractoriness of plastic refractory.

Zhengzhou Rongsheng Refractory Co., Ltd. leading refractory manufacturer in China, produces plastic refractory using high-quality refractory raw materials and selected plastic-clay. It still has certain plasticity after long-term storage.
