Essential Raw Material Difference
Natural rock chips are directly processed from natural ores such as mica, quartz and lapis lazuli through mechanical crushing, screening and sorting, with 100% natural mineral composition.
Composite rock chips are artificially synthesized products made by mixing inorganic mineral powder, polymer binder and artificial colorant through processes such as pressing, drying and slicing.
Physical Property Difference
Natural rock chips retain the unique natural layered crystal structure of minerals, with natural light transmittance and natural mineral luster, and the texture is relatively crisp.
Composite rock chips have uniform internal structure, adjustable hardness and flexibility, and are not easy to be broken during high-speed stirring and spraying construction.
Weather Resistance Performance Difference
Natural rock chips have extremely stable chemical properties, no discoloration or pulverization after long-term exposure to ultraviolet rays, acid rain and temperature alternation, and the outdoor service life can reach more than 15 years.
The weather resistance of composite rock chips depends on the quality of the adhesive and colorant. Ordinary products are prone to fading and pulverization after 3-5 years of outdoor use, and the service life is relatively short.
Color and Batch Stability Difference
The color of natural rock chips comes from natural minerals, with natural and rich texture, but there will be slight color difference between different batches affected by ore sources.
The color of composite rock chips can be precisely customized artificially, with 100% consistent color and particle size between different batches, and no color difference problem.
Typical Application Scenarios Difference
Natural rock chips are suitable for high-rise building exterior walls, coastal high salt spray areas, severe cold regions and other harsh outdoor scenarios with high durability requirements.
Composite rock chips are suitable for interior art coatings, ordinary residential exterior walls, and personalized decorative projects that require custom colors and cost control.
