XPS stands for extruded polystyrene, which is a foamed polystyrene board type used for insulation. Foamed polystyrene boards are commonly referred to as EPS. So, how do we separate them apart? Therefore, the letter ‘X’ was chosen to emphasise the process of production of extrusion.
XEPS stands for extruded expandable PS beads and XPET stands for extruded foam PET.
The agents for physical blowing will be inserted into the PS in molten conditions during the continuous extrusion process of XPS. After that, the cooling extruder cools the blowing agents, mixed PS, and other additives.
The pressured and also viscous molten material is extruded through the slotted die as a result. Pressure is released as the material will exude from the slotted die, and the process of foaming begins. To embody models and shapes, the foamed material will travel through the calibrating system.
Hot extrusion is another manufacturing procedure utilised in the CO₂ production line of foaming XPS foam. The continual mixing of a certain blowing agent (CO₂) into this molten polymer is the fundamental characteristic of this extrusion technique. A mixture of several components is made.
The mixture is then delivered to a dosing apparatus, which feeds it into this XPS extruder. The foam is directed through a mandrel after extrusion to give it its final shape
XPS foam board features
The manufacturing line of XPS type foam board will mostly be used to manufacture XPS foam type insulation board. Good cushioning, good elasticity, softness, non-toxicity, thermal insulation, compression resistance, sound insulation, and also moisture resistance are all advantages of XPS material.
The foaming agent will be injected into this extrusion line of your XPS foam board, which is comprised of polystyrene. Processes are used to create the completed insulation board for XPS foam. The closed-cell structure available of the XPS insulation board provides good strength, lightweight, good airtightness, and also anti-aging features.
How will XPS foam board be produced?
Because of its outstanding thermal insulation properties, extruded polystyrene board will be widely employed in key industries. Although the XPS type foam board production process is not overly sophisticated, we must pay close attention to all linkages in the process to ensure that your resulting extruded board meets national standards and also industry criteria.
In general, the following steps comprise the extruded polystyrene type foam board manufacturing process:
1.First step
This is mostly a plasticizing stage. We should use an automatic feeder to feed polystyrene resin, combustion aid, nucleating agent, and other materials into your first-stage plastic extruder.
2.Second step
The secondary foaming, mixing, and cooling process takes up the majority of the second stage. Before injecting an environmentally-friendly CO₂ foaming agent, the raw ingredients and other auxiliary materials are thoroughly plasticized inside the extruder.
In the second-stage extruder, the blowing agent will be fully mixed with a few other raw materials, chilled, and after that extruded through your die.
3.Third step
The pressure is soon released after extrusion, the foaming agent gets wrapped in the plastic that expands swiftly to create closed cells, and the polystyrene plastic will form a foamed panel along with honeycomb-shaped cells under various actions of the cells.
4.Fourth step
The shaping plate is then moulded using a shaping tractor to achieve the desired thickness and width, after which it can be cut to shape. This stage primarily regulates the board's thickness and width.
Besides the main machine, various auxiliary equipment is used in the extruded polystyrene board production process, such as an extruded board surface roughening machine, a recycling granulator, an edge shaping machine, a slotting machine, an automatic packing machine, and so on.
What are the various applications of these XPS foam boards?
In "green" structures, XPS foam boards will be the appropriate thermal insulation materials. They can also handle heavy loads and meet all the requirements of high-performance insulation needed in various branches of civil engineering, industrial floors.
General applications
•Basements thermal insulation
•Foundations thermal insulation
•Floors thermal insulation
•Walls thermal insulation
•Roofs thermal insulation
•Pools and utilities thermal insulation
•Parking decks
•Floors of cold storage
Extended applications
•For graphite XPS
Graphite XPS foam boards, which have a lower conductivity factor than normal XPS foam boards, will be made by mixing graphite with other basic materials.
•Integrated decoration and also insulation boards
It consists of three layers: a coating layer, a carrier layer, and an insulation layer, all of which are prefabricated and combined in the workshops.
•Integrated type XPS foam board used in walls
XPS foam boards will be placed between the layer of outer concrete layer and the wall, rather than being applied on the exterior walls of your building.
Why to select XPS Foam Board
•A more affordable pricing, a similar quality of XPS foam machine costs 10% to 20% less than a European production line of XPS.
•It uses 100% recycled materials. In Europe, the XPS extrusion line may only utilise expensive raw materials, whereas foam board manufacturing process can use only 100% recycled materials. Recycling EPS and GPPS, for example, can save a lot of money.
•XPS type foam insulation board can be created without HCFC and CFC using as blowing agents CO₂ and alcohol on the XPS extrusion equipment.
•In the first extruder, both twin and single screws can be employed. The output capacity varies between 200 and 2000 kilogrammes per hour.
•All assistive gadgets can now work online thanks to ground breaking technology.
•The energy usage of the XPS production line is reduced.
•CE certification is available for XPS foam machines.
