A manufacturing process and composition of acrylic composite materials with mineral charges with high thermal, mechanical and processing properties is provided for manufacturing kitchen covering, washstands, sinks, shower bases, tables, bars, counters, and furniture in general. A prepolymer composition in addition to methyl methacrylate in equilibrium contains, comonomers and elastomers that provide optimized and specific properties to the final products, such as high impact strength, product transformability in order to allow superior drilling, screwing and bending actions, as well as higher thermoforming possibility. The resulting component is a polymer matrix surrounding discrete particles of the elastomer and the mineral component.
