Physical and chemical indexes of products
Refractory materials with different indicators can be customized according to demand. Call 400-188-3352 for detailsIt can inhibit the shrinkage of plastic in curing, baking and high temperature use. Improve the toughness, mechanical impact resistance and mechanical strength of plastics. Improve the thermal shock resistance of plastics. Prevent microcracks generated in the plastic from expanding or extending under the action of thermal stress and mechanical stress to cause fracture or peeling. Scope of application: steel fiber high-strength plastic is mainly used in building materials industry and other industrial kilns where refractory materials are required to have good peeling resistance and impact resistance.| Project | Target | |||||
