In the toy industry, Polyethylene (PE) is often used to make toy housings, puzzles, beach toys, etc. Polypropylene (PP) can be used for toy parts, storage boxes, plastic building blocks. Polyvinyl chloride (PVC) can create dolls, inflatable toys, and soft rubber toy parts. Polystyrene (PS) is suitable for making toy models, transparent toy parts, and toy packaging. Acrylonitrile Butadiene Styrene copolymer (ABS) is used to manufacture structurally complex toys such as toy cars and robots. Polycarbonate (PC) can make toy parts with high transparency and strength requirements, such as the cabin of a toy airplane. Poly(methyl methacrylate) (PMMA) is used to make transparent decorative parts and display covers for toys. Polyamide (PA) can make key structural parts such as internal gears and joint connectors of toy guns, relying on its high strength and wear resistance to ensure the toy's lifespan. Polyoxymethylene (POM) is often used for precision parts such as drive shafts of toy cars and joint axes of toy figures to provide precise movement and structural support. Polyphenylene Oxide (PPO) is used for insulating parts and housings in electronic toys to ensure safety with outstanding insulation and stability.
