天然橡胶(NR)由于具有有益的性能(包括高回弹性和阻尼性能)而广泛用于如轮胎、胶管、手套、避孕套和气球等一系列产品中。但也必须考虑到其耐环境性和加工性都较差。在日常生活中,聚苯乙烯(PS)用于许多领域,如包装、容器、泡沫和家用产品。在这些产品中,PS因具有易加工性、宽熔点范围、刚性、优异的透明度、热成型期间低收缩率及低的成本而主要用于冰淇淋、酸奶酪、甜果酱或食品用的杯子。然而,PS非常脆。 Natural rubber (NR) is widely used in a range of products such as tires, hoses, gloves, condoms and balloons due to its beneficial properties, including its high resilience and damping properties. However, it must also be considered that its resistance to the environment and the processability are poor. In everyday life, polystyrene (PS) is used in many fields such as packaging, containers, foams and household products. Among these products, PS is mainly used in cups for ice cream, yogurt, sweet jam or food because of its ease of processing, wide melting point range, rigidity, excellent transparency, low shrinkage during thermoforming and low cost. However, PS is very brittle.
