1. Widely used for wall insulation, flat concrete roof and steel structure roof insulation;

2. Used for moisture-proof insulation in low-temperature storage ground, parking platform, airport runway, highway and other fields.

Extruded board is a rigid foam plastic board with continuous closed-cell foaming, which is made of polystyrene resin supplemented with polymer, injected with catalyst while heating and mixing, and then extruded. It has an independent closed bubble structure inside. It is an environmentally friendly insulation material with excellent properties such as high pressure resistance, low water absorption, moisture resistance, airtightness, light weight, corrosion resistance, super anti-aging (almost no aging after long-term use), and low thermal conductivity.

Extruded board is widely used in dry wall insulation, flat concrete roof and steel structure roof insulation, moisture-proof insulation in low-temperature storage ground, under low-temperature floor radiant heating heating pipes, parking platform, airport runway, highway and other fields, to control ground frost heave. It is a high-quality and inexpensive insulation and moisture-proof material in the construction industry.
