The table below shows the comparison between the properties of each construction material or other thermal proof materials and Eco foam. Obviously, Eco foam is superior to other

Product Overview

Eco foam is an alternative material with excellent properties in every aspect. Eco foam can effectively work as insulator and help in saving energy because it is made of polystyrene plastic in extrusion manufacturing process. The structure of Eco foam is a closed-cell structure polymer, so it is resistant to humidity and compression. Eco foam can be applied for many purposes, especially in construction industry. In Europe, Eco foam is accepted as a qualified material for insulation because it is non-toxic and harmless.

Eco foam is the best new alternative for people who are looking for excellent building material that is thermal proof, energy saving for air conditioner use, resistant to humidity from rain, and able to bear a lot of weight. These properties can be found in Eco foam, new innovative material for intelligent consumer.

Manufacturing Process

The excellent qualification of Eco foam PS foam comes from the manufacturing process that is different from the expanded polystyrene foam. Eco foam is produced by extrusion manufacturing process.

At first, the solid polystyrene in form of plastic granules will be injection molded to become Eco foam and then our secret additives will be added to enhance special properties for Eco foam. After that our high technology machine will put in the blowing agent substance to make Eco foam the high quality closed-cell structure foam that is different from other types of foam. The difference of cell structure between other polystyrene foam and Eco foam PS Foam is shown in the picture below.

Insulation for Building Platform

Eco foam can be used as humidity insulation to prevent building base from any damage, since this part of the building is always dampen by moisture from the ground. Apart from that, heat loss of the building can be prevented as well, because Eco foam is humidity and compression resistant, low thermal conductive, and not easily decomposed

Eco foam is also suitable for the basement and the building that has problem with groundwater.

Insulation for Building Roof (Flat Roof)

Eco foam is excellent in preventing temperature outside from entering the building, either heat, wet, or cold weather. To use Eco foam with flat roof, we can place the foam sheets, cover them with water proofing material, and then pave it with any solid surface, such as cement board or waterproof plywood. Also, we can even cover them with soil for growing small plants because Eco foam is non-water absorbing, so that we do not have to be worried about the moisture.
