ABS是一种常见的热塑性聚合物，由丙烯腈、丁二烯和苯乙烯制成。它具有强度高、韧性好、抗冲击性强、易于加工等优点，广泛应用于家用电器、汽车零部件、玩具、电子产品外壳和3D打印材料等领域。.
腈纶纤维是一种柔软、轻便的合成纤维。.
BR，即丁二烯橡胶的简称，是一种高性能合成橡胶，由丁二烯单体聚合而成。.
它是一种经典的夹心结构有机金属化合物。室温下呈橙黄色针状晶体或粉末状，具有类似樟脑的特征气味。熔点：172–174℃；沸点：249℃；在100℃以上可升华。不溶于水，易溶于苯、乙醚、汽油和柴油等有机溶剂。化学性质稳定，对空气和水分不敏感，热稳定性约为400℃。
Medium‑high nitrile NBR, short for medium‑high acrylonitrile butadiene rubber, is a widely used oil‑resistant synthetic rubber produced by copolymerizing acrylonitrile and butadiene, offering an excellent balance of oil resistance, elasticity and mechanical properties for industrial sealing and automotive applications.
PE stands for polyethylene, a lightweight and corrosion-resistant plastic material widely used in pipelines.
Polyamide is a strong, flexible, and wear-resistant synthetic polymer with good thermal stability and chemical resistance, widely used in textiles, engineering plastics, and industrial parts.
Polyester is a widely used synthetic polymer fiber and plastic. It is strong, durable, wrinkle-resistant, quick-drying, and easy to care for. It is commonly used in textiles, clothing, packaging and industrial materials.
PP is polypropylene, a lightweight, heat-resistant and corrosion-resistant plastic material.
PVC is polyvinyl chloride, a widely used rigid plastic with high strength and low cost.
SBR (Styrene-Butadiene Rubber) is a widely used synthetic rubber with good abrasion resistance, elasticity and processability.
