When sourcing plastic bathroom sets (soap dispensers, toothbrushes holders, etc.), prioritize ABS (Acrylonitrile Butadiene Styrene) or PP (Polypropylene). ABS is preferred for its high impact resistance and ability to hold electroplated or metallic finishes effectively. Ensure the materials are BPA-free and meet REACH or RoHS standards to guarantee they do not leach harmful chemicals in humid environments. For transparent items, Acrylic (PMMA) or PS (Polystyrene) are common, but Acrylic offers superior clarity and UV resistance, preventing yellowing over time.
