EPS泡沫板是一种优良的包装材料，如电视机、冰箱、空调、玻璃器皿、陶瓷等商品，离不开泡沫包装作为缓冲包装。 EPS泡沫板是由聚苯乙烯树脂和发泡材料加热发泡后制成的轻质材料。 EPS具有泡沫轻、导热系数低、吸水率低、耐水性低、耐老化等优点。是蔬菜保鲜、保温盒保鲜等的容器，EPS泡沫板简单回收再利用。它是一个绿色包装。
EPS foam board is a good packaging material, such as TV, refrigerator, air conditioner, glassware, ceramics and so on. Cannot do without foam packaging as cushion packaging. EPS foam board is made of polystyrene resin and foamed material after heating and foaming. EPS has the advantages of light foam, low thermal conductivity, low water absorption, low water resistance and aging resistance. It is a container for keeping fresh vegetables and keeping fresh boxes. EPS foam board is simply recycled and reused. It's a green package.
EPS是一种有机碳氢化合物。一般的EPS制品除了发泡后呈多孔状态，含有残留石油气外，都是易燃的。它们可以被火点燃并在燃烧时发光。即使它们离开火焰，它们也会继续燃烧，伴随着烟雾和熔滴。自燃和外燃温度分别为490℃和296℃。没有阻燃剂的普通EPS泡沫被归类为“易燃”。遇火燃烧，火焰迅速蔓延至整个表面。如果存在足够的氧气并且排放了烟雾，EPS 将完全燃烧。因此，在储存和使用过程中要注意，特别是不要遇到明火，要严格隔离其他火源，注意原料仓库等生产场所的通风。 EPS燃烧时，可用所有消防器材灭火，也可用水灭火。
EPS is an organic hydrocarbon. The general EPS products are flammable except that they are porous after foaming and contain residual petroleum gas. They can be ignited by fire and glow as they burn. Even if they leave the flame, they will continue to burn, accompanied by smoke and droplets. The temperature of spontaneous combustion and external combustion are 490 ℃ and 296 ℃ respectively. The ordinary EPS foam without flame retardant is classified as "flammable". In case of fire, the flame spreads rapidly to the whole surface. If there is enough oxygen and smoke is emitted, the EPS will burn completely. Therefore, in the process of storage and use, we should pay attention, especially not to encounter open fire, strictly isolate other fire sources, and pay attention to the ventilation of raw material warehouse and other production places. When EPS burns, it can be put out with all fire fighting equipment or water.
Another factor to be considered in fire prevention is the release of heat. The burning value of EPS is 40436KJ/kg, which does not necessarily mean that the EPS foam will release a lot of heat when it burns. In this case, the main factor is the burning rate.
Because they are lightweight, when EPS is used as insulation and packaging material, it does not release a lot of heat to support combustion in a fire.
The ignition performance of EPS foam (except for the properties of the material itself) also depends on many factors, including geometric properties, surface area, approximation to other articles, fire source, composite structure, nature and energy of fire source, time of facing fire sources, heat treatment and ventilation.
在评估 EPS 泡沫使用中涉及的火灾危险时，应考虑所有这些因素。表面覆盖、分层和与其他材料复合可以改变产品的耐火性。
All these factors should be considered when assessing the fire hazards involved in the use of EPS foam. Surface covering, lamination and compounding with other materials can change the fire resistance of products.
When EPS products are used in construction, shipbuilding, refrigerated vehicles and other fields, certain flame retardant requirements must be put forward. Due to the addition of flame retardants such as organic halides, the combustion performance of flame retardant EPS is greatly changed, and the application scope of EPS is expanded.
Although it may be ignited when exposed to the flame for a long time, the flame spreads to the whole surface very slowly. When the external flame moves away, the EPS foam will not continue to burn and will not leave any afterglow. This indicates that the EPS foam will not burn completely unless it is directly affected by other more flammable substances.
