Raw Material
Qingdao Zhongxin Huamei, a CHIMEI joint venture and a 30+ year original factory, specializes in customizing ABS, PC, PA, PMMA and PBT plastic granules with flame-retardant, reinforced, antistatic, light-diffusing and infrared-transmitting properties. Backed by a professional R&D team, we offer free samples and technical support for global clients.
PP Performance Advantages:
• Ultra-lightweight: Density of 0.90-0.91g/cm³, the lowest density among common plastics.
• Chemical resistance: Resistant to acids, alkalis, and ethanol, with no easy corrosion.
• Wide temperature resistance: Heat distortion temperature of 100-120℃ (microwave-safe), no brittleness at -20℃.
Typical Applications: Microwave lunch boxes, bumpers, household water supply pipes, inner layers of masks
