What are the factors affecting the ignition performance of EPS ?
EPS Foam are very common items in everyone’s life. Many of the daily items we use are made of plastic. Everyone will see EPS products to protect the product when taking delivery. With the development of production technology, the research and development of foam plastic products such as EPS board has been loved and praised from the market. EPS has ignition properties, so what are the factors that affect its ignition performance?
The ignition performance of EPS also depends on many factors, including the nature of the item, that is, their geometric characteristics, surface area, similarity to other items, fire source, composite structure, nature and energy of the fire source, facing the fire source The length of time, as well as heat treatment and ventilation.
When EPS products are applied in the fields of construction, shipbuilding, refrigerated vehicles, etc., flame retardation requirements must be raised. The flame retardant EPS raw material has greatly changed its combustion performance due to the addition of flame retardants such as organic halides, and expanded the scope of use of EPS. Although it may ignite when it is exposed to the flame for a long time, the flame spreads slowly across its entire surface. When the external flames were removed, the EPS foam did not continue to burn and no afterglow was seen.
