What material is the shooting target made of

Resin acid (C19H29COOH) and binder (IVGP-20) instead of coal tar pitch, with heavy calcium carbonate instead of gypsum powder, constituting a composite material, used to replace the world's traditional asphalt gypsum powder composite materials, manufacturing shooting skeet target. The results show that the material made of flying saucer target, not only the performance indicators are better than the asphalt target, and after the use of the debris also has the function of environmental degradation, non-toxic in the production and use of the process of non-toxic, tasteless, non-stimulation, no pollution of the environment.

Originally made of asphalt gypsum powder composite material, now there are many new materials to use.
