Understanding hair dryer plastic housing materials is crucial for wholesale buyers and manufacturers. ABS (Acrylonitrile Butadiene Styrene) dominates the market due to its cost-effectiveness and excellent processing characteristics, representing 40-60% of manufacturing expenses. Polycarbonate offers superior heat resistance up to 130°C, making it ideal for professional-grade dryers. PC/ABS blends have emerged as the industry standard, combining optimal performance with competitive pricing. Material selection must balance safety compliance, including UL94 flame ratings, with manufacturing efficiency and market positioning. Budget segments rely on standard ABS for cost-effectiveness, while premium markets justify polycarbonate through enhanced durability and safety margins. This comprehensive guide examines material properties, safety requirements, manufacturing costs, and market segmentation to help wholesale buyers make informed decisions that protect profitability and ensure product quality across all price points.
