Using CO2 gas technology for food
Remak® XPS applies advanced production technology, using food grade CO2 as an expansion agent. Our foam sheet becomes a breakthrough material with outstanding characteristics, such as sound insulation, heat insulation, waterproof, compressive strength… and durability.
At the same time, Remak® XPS also demonstrates a commitment to the environment and social responsibility. Therefore, although it has just launched on the market, the foam of Remak Construction & Interior Joint Stock Company has quickly been recognized by customers, contractors, investors, design and construction units.
Roles of CO2 in industrial production and life
Carbon dioxide is a widely known chemical compound that exists all around us and is known by its chemical formula as CO2.
When it comes to CO2, surely most of us immediately think of this as a toxic gas found in nature, produced during the respiration of humans and animals. Perhaps because we are familiar with the concept of CO2 causing environmental pollution, not many people are aware of the benefits and applications of this gas in industrial production and life, such as:
-
CO2 gas used in food industry: creating gas for drinks, making baked goods, removing caffeine in coffee, etc.
-
CO2 gas used in industrial: used in life jackets or air tubes in air guns, bicycle pumps, fire fighting, welding technology, etc.
-
CO2 gas used in medical industry: dry ice is used by hospitals and laboratories, in the fields of pharmaceuticals and chemical industry, applied in greenhouses to provide gas for plants, high CO2 concentration to kill many types of insects and pests.
- CO2 gas used in life: dry ice, also known as smoke stone, is used to create stage fog effects in wedding events, game shows.
Remak® XPS foam production line using CO2 gas for food
|
XPS foam is a material that has become familiar and popular in the construction industry today. This type of foam is often used for construction of heat insulation – heat protection, sound insulation – noise reduction, moisture resistance, leakproof for buildings, construction works, etc. However, according to scientists, most XPS products on the market are being manufactured using old technology, using HCFC-22 (traditional gas) as an expansion aid in the production line. In the long run, this substance causes negative effects on the ecosystem, depleting the ozone layer. Meanwhile, Remak® XPS foam board produced by Remak Construction & Interior Joint Stock Company applies breakthrough advanced technology: using food-grade CO2 instead of HCFC-22. This is a gas with the purity of more than 99.8%, ensuring no having dust and impurities harmful to human health.
Therefore, even Remak® XPS has launched since the beginning of 10/2022 it has affirmed its advantages, quickly being favored by contractors, investors, design and construction units… for projects.
Some outstanding features of Remak® XPS using CO2 technology, include: • The previous XPS manufacturing process used stimulant gases such as Chlofluorocarbon (CFC), Hydrochloroflurocarbon (HCFC) which are toxic, increasing the greenhouse effect, warming the earth and causing the destruction of the ozone layer. • Remak® XPS is produced with pure CO2, so it is classified as a green material, does not contain substances harmful to the environment, does not cause allergies, and is safe for human health. And it becomes a sustainable and highly profitable solution for projects. • Vietnam is one of the early countries to join the Vienna Convention on the protection of the ozone layer and the Montreal Protocol on substances that deplete the ozone layer (since January 1994). Accordingly, the newwtechnology of applying CO2 as an expansion aid (replacing gas as the traditional method) in the Remak® XPS foam production line is an environmentally friendly technology that fully meets the criteria set by the Multilaterial Fund and ensures compliance with legal regulations. • Besides, CO2 gas also has the advantage of being a light molecule, being a fire retardant in construction, having mechanical properties and long-term durability. |
Synchronous, advanced and modern Remak® XPS foam production line
Remak® XPS sheet is produced in advanced production lines, extruded into solid insulation foam sheets by high-pressure sealed mixing technology
- Advanced machinery and equipment, suitable for extrusion technology using CO2 in food industry.
- Automatic, high-precision zero-gravity input weighing system.
- The central control system controls the process of evenly mixing plastic with CO2 according to a certain standard ratio before extrusion process to create porosity and uniform air pockets, high density.
- The main material to create Remak® XPS foam sheet is high-grade Polystyrene virgin plastic imported from Korea – a pure, clean, safe and zero-emission plastic during construction and use.
Remak® XPS – the best insulation foam in Vietnam market
Because it is manufactured by high-grade materials, applied advanced technology, and rigorously monitoring, the finished product of Remak® XPS achieves perfect quality. Remak® XPS is rated as the best soundproof, heat insulation, moisture-proof, leakproof material on the market today, fully meeting the criteria of a green building material according to international standards.
Besides, Remak® XPS has the outstanding advantage of being very light in weight but durable and highly compressive as well as cost-competitive. Compared with PU insulation, the cost of Remak® XPS panels is half that but has twice the compressive strength. Compared to EPS foam, Remak® XPS foam is 10 times more waterproof. Test results at the Vietnam Institute of Building Materials (VIBM), Ministry of Construction on some XPS models currently popular on the Vietnamese market show that: at the same density, but Remak® XPS has durability, coefficient of thermal conductivity, sound insulation coefficient and moisture resistance are all better than other XPS types
Remak® XPS for high energy efficiency
Remak® XPS manufacturing technology uses food-grade CO2 for great energy efficiency. According to scientists’ estimates, the conversion of using CO2 gas in the production of Remak® XPS foam helps reduce up to 460 million tons of CO2 emissions per year into the environment, and at the same time contributes to completely eliminating 100 tons of HCFC-22 in the XPS foam production in Vietnam.
Remak® XPS panels also reduce large amounts of greenhouse gas emissions and provide the most effective solution to thermal insulation problems in buildings. The application of XPS insulation foam for roofs and walls can cut energy use in half. In Europe, for example, using XPS insulation foam in buildings save roughly of 3.3 million barrels of oil per day.
Advanced technology for top product quality and environmental friendliness are two main factors that make the difference of Remak® XPS foam. The value of Remak® XPS is not only in energy efficiency, high applications, reasonable price, which saves a variety of costs but also in sustainability – a green solution for all buildings, environment and ecosystem as well as human health.

Recent studies of newly constructed buildings prove that: commercial buildings using XPS insulation panels with a thickness of 15-18cm can save annual electricity consumption from 343-344KWh /m2 (www.styropor.de). It is equivalent to every year, every 1m2 of XPS insulation used will save about 1,000,000 VND (electricity price 2500 VND/KW). When compared to heating oil consumption, 1kg XPS saves about 400 liters of heating oil over 50 years.
