Beijing polystyrene board manufacturer, polystyrene foam board
Hourly sales hotline
Text>Polystyrene foam board is made of polystyrene resin as raw material. It is a kind of high pressure resistance and non-absorbent material. , moisture-proof, airtight, lightweight, corrosion-resistant, environmentally friendly insulation material with excellent properties such as long service life and low thermal conductivity.
The abbreviation of the expanded polystyrene foam board produced by our company using advanced technology is divided into ordinary type and flame-retardant type. The density is /, the thermal conductivity coefficient at normal temperature is /(), the base board size is **, and can be pressed Users require cutting into different shapes and sizes.
Product Features
Foam board has the advantages of light weight, thermal insulation, low water absorption, and low temperature resistance. /Copy
Main uses
Floor heating, color steel plate sandwich, cold storage insulation, building basement water insulation, building roof insulation, exterior wall insulation, etc.
Special introduction: When making exterior wall insulation boards, our company's board production line adopts our company's patented product tunnel-type constant temperature room, which can not only continue large-scale production (square meters/day, thickness mm), but also ensure New products released every day have been matured in a constant-temperature room for more than a day and can be used directly on the wall to ensure that the wall will not crack
According to the national construction industry standard "Expanded Polystyrene Board Thin Plastering Exterior Wall Exterior Insulation System"
Foam molding theory
Foam plastics use plastic as the basic component and contain a large number of bubbles. Therefore, foam plastics can also be said to be composite plastics with gas as filler.
According to the physical properties of the plastic and the softness and hardness of the foam texture, foam plastics can be divided into three major categories. Polystyrene foam, phenolic foam, epoxy foam, and some polyurethane foams are rigid foams, while rubber, elastic polyurethane, and some polyolefin foams are soft foams.
Expandable polystyrene resin is a low-boiling liquid foaming agent added to polystyrene beads. Under the conditions of heating and pressure, it penetrates into the polystyrene beads to cause them to swell. Made into expandable polystyrene resin (beads).
When heated, polystyrene softens and low-boiling alkanes volatilize, causing polystyrene particles to expand. Using this principle, it is produced through pre-expansion, aging, molding, drying and cutting. Expandable polystyrene products.
It can be used to make foam plastic products of different densities and shapes, and can also produce foam plastic sheets of various thicknesses, which are widely used in construction, packaging, daily necessities, industrial products and other fields.
