Talc

Introduction:

The chemical composition of talc is Mg3[Si4O10](OH)2, and the crystal belongs to the layered silicate mineral of triclinic system.Pseudo-hexagonal single crystals are rare, and they are usually dense massive, bladelike, fibrous or radial aggregates.White or various light colors, streaks are often white, fatty luster (lumpy) or pearl luster (patchy aggregate), translucent.Mohs hardness 1, specific gravity 2.6-2.8.A set of extremely complete cleavages, flakes flexible.Slippery feeling, strong heat insulation and insulation.

Applications: 

          Plastic grade talc for plastics in the industrial use of special attention to the toughness and wear resistance of this plastic. Plastics are generally hard, horn-like, with good wear resistance and high dimensional stability. These properties can be further enhanced by fillers or reinforcers.

          In all kinds of fillers, plastic grade talc with layered structure can improve the original good properties of plastics, and it is very important to improve the wear resistance. 

          Compared with metal filling modified plastics not low elastic modulus, tensile and creep strength is low, have obvious dependence of mechanical properties and temperature of molecules containing the suction gene, bibulous rate is high, the products easy to swell deformation when using, fast cooling crystallization incomplete when processing molding, when use in crystallization, this leads to deformation, and even cracking. 

           The above shortcomings of plastic, adding superfine plastic grade talc master material can have a great improvement, plastic grade talc has the effect of nucleating agent, adding can improve the crystallization rate of plastic, increase the degree of crystallinity; Therefore, it can especially improve the plastic's toughness, mechanical strength, hardness, thermal stability, dimensional stability, improve the surface quality of products and deformation behavior, for moisture absorption, electrical properties and chemical properties also have a good impact.
