Synthetic Marble Sink: A Comprehensive GuideWhat is a Synthetic Marble Sink?A synthetic marble sink is a high-performance bathroom or kitchen fixture crafted from engineered stone composites. These sinks blend crushed natural marble (typically 70-90% by weight) with polymer resins (usually 10-30% polyester or acrylic) under vacuum vibration compaction. The resulting material achieves a density of 2.4-2.7 g/cm³, closely matching natural stone while offering enhanced technical properties. Modern manufacturing techniques like Bretonstone processing create non-porous surfaces with water absorption rates below 0.1%, significantly outperforming natural marble's typical 0.5-1% absorption.Key Characteristics with Technical SpecificationsSurface Hardness: Rates 3-4 on the Mohs scale, comparable to natural marble but with improved impact resistance (withstanding up to 150 Joules of impact energy)Thermal Stability: Maintains structural integrity between -30°C to 150°C, with a coefficient of thermal expansion of 8-12 x 10^-6/°CChemical Resistance: Demonstrates pH stability between 3-11, resisting common household acids and alkalis better than natural stoneHygienic Properties: The non-porous surface (<0.02% porosity) inhibits bacterial growth, achieving >99% reduction in E.coli and Staphylococcus aureus within 24 hoursColor Consistency: Maintains ΔE<2 color variation under accelerated UV testing equivalent to 10 years of sunlight exposure
