Polystyrene is a polymer synthesized by free radical polymerization of styrene monomer.it is a colorless transparent thermoplastic, has the glass transition temperature higher than 100 ℃, thus is often used to make various need to bear the disposable containers of boiling water temperature, and disposable foam lunch boxes, building insulation materials, etc.

 

The full name of extruded polystyrene board is extruded polystyrene foam board, short for extruded board, also known as xps board, extruded polystyrene board.it based on polystyrene resin as raw materials and other raw materials and inclusion, inject catalyst by cooking at the same time, and then extruded extrusion molding and manufacturing of hard foam plastic board. Its scientific name is adiabatic with extruded polystyrene foam plastic (xps), xps with perfect obturator honeycomb structure, this structure makes xps board has a very low water imbibition (almost no water absorption), low thermal conductivity coefficient, high pressure resistance, aging resistance (normal use almost no decomposition of ageing phenomenon), is a special thermal insulation layer of floor heating material.the picture shows green plywood.

 

Polyurethane is a kind of polymer which contains ammonia ester type repeating structure unit in the macromolecular chain.polystyrene insulation is the product reflected by polyisocyanate and polyether or polyester polyol in a certain proportion.polystyrene foam board is a kind of polyurethane sandwich board, which is made entirely of pu or formed by pu and color steel plate composite. It is mainly used in the external insulation system of industrial and civil buildings.

 

Glass cotton is a glass cotton rolled felt product made by melting glass and making it fibrous. The diameter of glass cotton fiber depends on centrifugal extrusion technology.fiberglass panels are used for insulation, heat insulation, sound absorption and noise reduction of building exterior walls, and heat insulation of industrial kilns.steel insulation board sandwich, etc.

 

Eps plate is made of volatile liquid foaming agent containing volatile polystyrene bead particles, which are heated in the mould after preheating and forming white objects, it has the structural characteristics of small closed holes.the white foam used as packaging when buying a computer is eps.

 

Rubber sheet is a kind of sheet product with certain thickness and large area, which is made by vulcanization.rubber has high hardness, physical and mechanical properties, can be in pressure is not big, the temperature is 20 ° ~ + 140 ℃ of work in the air.the rubber plate is made of mixed rubber which is formed or extruded by pressing and sticking, vulcanizing by plate vulcanizing machine or continuous vulcanizing by drum vulcanizing machine.color: Black, gray, green, blue, etc.widely used in industrial and mining enterprises, transportation departments and housing ground.used for sealing gaskets, gaskets, door and window seals and laying workbenches and floors.
