Does polyvinyl chloride (PVC) plastic have an odor?
PVC塑料燃烧后会有气味。
PVC plastic will have an odor after combustion.
聚氯乙烯的燃烧特性为，难燃、离火即灭、火焰呈黄色，白烟，燃烧时塑料变软发出氯的刺激性味。
The combustion characteristics of polyvinyl chloride (PVC) are that it is difficult to ignite, extinguishes immediately after ignition, the flame is yellow, white smoke, and the plastic softens during combustion, emitting a stimulating odor of chlorine.
大多数聚氯乙烯塑料制品的长期使用温度不宜超过55℃，但特殊配方的聚氯乙烯塑料的长期使用温度可达90℃。低温下软质聚氯乙烯制品会变硬。聚氯乙烯分子中由于含有氯原子，因此它和它的共聚物一般能耐燃耐焰，具有自熄性，无滴落性。
The long-term use temperature of most PVC plastic products should not exceed 55 ℃, but the long-term use temperature of specially formulated PVC plastic can reach 90 ℃. Soft polyvinyl chloride products will harden at low temperatures. Due to the presence of chlorine atoms in polyvinyl chloride (PVC) molecules, it and its copolymers are generally flame resistant, self extinguishing, and non dripping.
