Mainly used for foam molding, used as heat preservation, heat insulation, shockproof, packaging materials and floating products. The general type (R) is suitable for packaging materials; the flame-retardant type (F) is suitable for construction and thermal insulation materials.

Several well-known companies have successively used different process technologies to vigorously carry out applied research in their respective fields, and constantly develop new products. They not only have a large market in their own countries, but are also outstanding in the world. The development of styrene industry has played a leading role.
