What is XPS?
The thermal insulation board is composed of several materials, such as: asbestos board, polyurethane foam board, and XPS board. The XPS board refers to a hard polystyrene foam board produced by direct extrusion. The role of XPS and some other panels in housing and other construction and engineering areas is thermal insulation. In addition, XPS can also be applied to the packaging of goods. As a building insulation material, XPS panels can significantly reduce fuel consumption (ie oil, natural gas, etc.) or electrical energy for heating. The production process allows these panels to have a small, tightly closed molecular structure that maintains the heat-conducting gas in a very limited space for thermal insulation. This feature also imparts impervious properties to the board. You can buy XPS in the building materials market. It can also be purchased from the manufacturer of the XPS board. Depending on the manufacturer, the color of the board varies, such as pink, blue or green. We can also produce special XPS insulation boards according to different requirements of customers.

What is EPS?
Of course, EPS also refers to expanded polystyrene. But his molding method and XPS are significantly different. In EPS, a foaming agent is previously mixed into PS and then granulated. The produced PS pellets contain a foaming agent. When an appropriate amount of PS pellets containing a foaming agent is placed in a predetermined mold for heating, the foaming agent in these pellets is thermally foamed and finally formed. EPS is also used for insulation of floors, walls and ceilings. In addition, it is used in the same way as XPS under structures with low capacity such as civil engineering, earth embankments and highways. The extrusion process of EPS is different from XPS. As a result, EPS is different from XPS in appearance and physical properties, and its thermal insulation effect is also inferior to XPS. The EPS plate weight is usually in the following range: 10-35 kg/m3 (0.62-2.18 lb/ft3).
Compared with XPS, EPSXPS is closed and the foamed spherical molecular structure is closed and the foamed cellular structure has high water absorption rate. The water absorption rate is very low. The lower the capital investment, the higher the capital investment weight, the lighter weight, the relatively heavy production cost. High (including material cost) production cost lower dimensional stability better dimensional stability very good pressure resistance is not strong pressure resistance strong thermal conductivity higher thermal conductivity lower output lower output higher non-toxic poison
XPS board application features:
First, high compressive strength, extruded hot plate has various models of 150KPa--600KPa, which can meet various load requirements. Such as: square ground, roof parking, roof tennis courts, roof gardens, platforms and grounds, highways and railway subgrades that are subject to long-term loads.
Second, the superior thermal insulation performance, as a thermal insulation material, the extrusion coefficient of the extruded board is less than 0.03w / mk, at 70% relative humidity, the extruded board is obvious in this respect, the extruded board in this respect It is obviously superior to other insulation materials, and its thermal insulation performance changes little with time. Its insulation performance can still be above 80% after several decades of use.
Third, good sound and noise reduction performance, the unique sound insulation and noise reduction performance of the extruded board, so that you can stay in the hotel, whether in the hotel or in the KTV room, or at home, do not have to worry about the outside interference and influence others. Especially in the decoration and engineering decoration.
4. Excellent moisture-proof and moisture-proof performance. The extruded board has a compact closed-cell honeycomb structure. The polystyrene molecules themselves do not absorb water and have excellent water vapor permeability resistance. The water absorption rate is higher than that of ordinary expanded polystyrene. The plate should be about 10 times smaller, only absorb a small amount of water in the initial stage, and then no longer absorb water; its water vapor permeability is 2-4 times smaller than that of expanded polystyrene. Therefore, in addition to effectively preventing the intrusion of rainwater and the penetration of moisture, the extruded board can effectively prevent water from accumulating inside the material due to condensation and bursting due to melting.
5. Excellent environmental performance, the extruded board has stable chemical properties, is not volatile decomposition, mildew; has good corrosion resistance, its high-performance thermal insulation function can reduce the consumption of natural resources; the solid waste generated by it can be Recycling and use, fully in line with the requirements of the world's sustainable development strategy, is a new type of environmentally friendly products.
We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
