Production Technology and Standards | Bonus XPS
Polystyrene foam (XPS) with “Bonus” brand, produced in a fully automated system with the extrusion technology, is a thermoplastic material with homogeneous cell structure, which is used for thermal insulation.
XPS is produced under constant pressure by means of a continuous extrusion process. Its main raw material is polystyrene and cell formers, flame-retardants, paint and inflater gases are also used in its production. Thanks to its production via full automation under constant computer control, a stable cell structure with homogeneous honeycomb (hexagonal) appearance is achieved. Cells are interconnected through all surfaces. Extruded polystyrene materials (XPS) do not absorb water and are not affected by humidity due to their hexagonal, closed porosity, They have optimum water vapor diffusion resistance and a low thermal conductivity coefficient value.
Process and quality control processes have been established in all stages of the production with the full automation system and all data are recorded. Furthermore, the traceability of products can be ensured with the assistance of the automatic time-adjusted labeling system.
With its infrastructure in full automation extrusion process and product development activities, Eryap Group produced Turkey’s first extruded polystyrene foam with 700kPa compressive strength and low thermal conductivity coefficient. The Group proved the production of the 700kPa product with accredited laboratory reports, in addition to the tests conducted in its own laboratories.
The surface of the material produced in the process is structured as armored or rough surface, according to the purposes the material will be used for. The Group can respond to customer expectations and all kinds of special product demands thanks to its extrusion technology and product development infrastructure. Many product development activities are conducted in its R&D department every year. The products developed as a result of these studies are produced and sold.
Although there are no restrictions in our country yet regarding the use of permanent organic pollutant (HBCD) flame retardant in the XPS production industry, Eryap Group, which aims to pioneer the sector in this matter as well, has initiated the infrastructure works upon the beginning of the use of flame retardants not containing HBCD in Europe.
During the production of XPS thermal insulation plates, CO2 may also be used as the inflater gas, and no harm is done to the environment both during production process or use of the products.
Following an environment friendly policy, Eryap Group focuses on the use of CO2 as the inflater gas in XPS production. Furthermore, it is planned to lead studies for the use of alternative environment friendly gases in XPS production with a social responsibility awareness, considering that our country is party to the Kigali Amendment after Kyoto Protocol.
Eryap Group, which aims to use power sources with ultimate efficiency at its production cycle, contributes significantly to power saving with its products, and supports the sustainable development of Turkey and the world. In this respect, the Group closely follows all platforms and legislations for the protection of the environment.
