Monocell

Brand information

MONOTEZ S.A. produces EPS (expandable polystyrene) under the Monocell® trademark. Our product range offers grades with flame retardant additives (FR grades) or without (R grades).
Monocell ® is delivered as a raw material able to be expanded and then molded as foam over a wide density range, for the production of boards or shape molded elements used in buildings thermal insulation. It is also used in the production of packaging for the food industry and other specialized applications. Monocell ® is available in a range of grades that allows a choice for the use of the appropriate bead size, depending on the final application and the respective technology.

EPS Application:

Expandable Polystyrene is a thermoplastic material ,in spherical bead shape, which contains Pentane as blowing agent, and is obtained as a result of the polymerization of styrene monomer.
The transformation process of expandable Polystyrene is accomplished with water vapor and the volume of the beads reaches 40 times the original one within less than a minute.

MONOCELL ® as Raw Material vs Expanded Polystyrene
“Expanded Polystyrene (EPS)” Production Process

There are five production phases , in the “Expanded Polystyrene” process, by using the MONOCELL ® as raw material:

Pre-expansion: Every Polystyrene granule is expanded by being exposed to steam in order to make larger grains consisting of series of closed cells.
Conditioning: After the expansion, the beads are still containing condensed vapor and pentane gas in small quantities. After being cooled down, air replaces partially the above components and diffuses gradually into the pores.
Molding: These beads are molded in order to form boards, blocks or products in other shapes. The mold serves to shape the desirable product and to retain the pre-foam. Steam is used in order to promote expansion again and causes the fusion of every single bead with its neighbors. Thus, a homogenous product is formed.
Shaping: After a short cooling period, the molded block is taken off the machine and after an additional conditioning, it can be cut into desire shapes by using a hot wire element or other appropriate techniques.
Post-production-processing: Finished product can be laminated with other coverings i.e. foils, plastics, roof felts, fiber-board or roof or wall cladding materials.

User advantages

Excellent Thermal Insulation: EPS is constituted 98% from air and therefore it is an excellent thermal insulant.
Proved Acoustic Insulator: It absorbs sound, both impact sound in floating floors and airborne sound for walls.
Resistance to Moisture: EPS is resistant to degradation by water.
Lifetime Durability: EPS is not decomposed. Therefore it ensures lifetime durability.
Flexible Mechanical Features: Due to the flexible production process, the mechanical feature of EPS is compatible with almost all applications.
Versatility: EPS is producible in almost all shapes or sizes and is compatible with a wide range of materials.
Cost Effective: Compared to other insulation materials EPS provides the best price/performance ratio.
Easy in Transportation: EPS is almost light as air, so it ensures fuel saving in transport.
Easy to Install:EPS is lightweight, practical, safe and it is easy to handle and to install.
