Double-slotted XPS

xps plates(extruded polystyrene sheets)

The XPS (extruded polystyrene) plate is a waterproof and highly compression-resistant plate.

The manufacturing process of extruded polystyrene (XPS) foam products is similar to that of expanded polystyrene (EPS) foam products.


Product Description

Huamei plastic extruded polystyrene sheets (XPS sheet)are serial products developed through special techniques according to the requirements of exterior wall insulation systems. For external insulation system for thin plaster exterior wall, there are pattern coating and stucco coating (coarse stucco and fine stucco) with both-side notches on the coating, which have the following features: easy and convenient operation, increased mortar adhesion area and enhanced adhesion strength, and all of these ensure sound stability, weather resistance and durability of the external insulation system for the exterior wall. Huamei plastic extruded plates are the best choice for exterior wall insulation systems.

How is xps plates Made?


The manufacturing process of extruded polystyrene (XPS) foam sheet products is similar to that of expanded polystyrene (EPS) foam products. Both start with the same basic raw materials. But in the case of extruded polystyrene, polystyrene resin beads or pellets are fed into the extruder, where they are heated at a very high temperature until they melt. At this time, various additives are added to the molten mixture. One of these additives may be a colorant. Extruded Polystyrene Sheets are usually colored in multiple colors to identify them as a specific brand. For example, Owens Corning XPS foam sheet board is usually pink, while Dow XPS foam board is usually blue. Blowing agents are also added to expand the product after the extrusion process. Using carefully controlled heat and pressure, the plastic mixture is forced through a die (extrusion), then cooled and expanded into the desired shape. The resulting foam board is then trimmed to the final product size. Because the foam board is extruded, rather than poured into a mold like EPS foam board, the thickness of XPS products is limited.

Insulation performance of Extruded Polystyrene Sheets


XPS foam is considered to have a closed-cell structure, where the cells are closely packed together and there are no voids or spaces between them. The tightly packed unit of XPS foam helps prevent air and water from entering, making it more suitable for humid environments.

Strength and rigidity of Extruded Polystyrene Sheet

XPS foam has a tightly packed closed-cell structure, making it very strong and strong, making it an ideal choice for structural panels.

Other attributes

Compressive strength. XPS foam board is a rigid material with very high compressive strength. The product has a homogeneous closed cell cross-section with no voids, and each cell is completely closed by a polystyrene wall, giving it impressive strength. The product has a variety of compressive strengths to meet different applications. The manufacturing pressure of XPS foam board can reach 100 psi or higher.

Durability. Since XPS foam sheet board is a thermoplastic material, it will not rot or decompose over time. It can also resist microorganisms in the soil. Moreover, it is not attractive to rats and other pests as a food source. Its service life is up to 50 years.

Chemically inert. XPS foam sheet board is considered a fairly chemically inert material. It is resistant to most acids, alkalis and aqueous solutions of salts and alkalis. However, many organic solvents such as acetone, chlorinated solvents, and aromatic solvents can attack and dissolve foam.

Size and density. XPS foam boards can be manufactured with or without plastic finishes.

energy efficiency. XPS foam sheet board is an energy-saving building material. Buildings insulated with XPS foam panels save much more energy throughout their lifecycle than the energy used in the manufacturing process of the products.

Dimensional stability. XPS foam board will expand and warp significantly at higher temperatures.

Sustainability. When used as insulation for homes or buildings, XPS foam panels have been proven to reduce the energy required to maintain their heating and cooling, thereby reducing the consumption of our depleted natural resources. Moreover, since polystyrene resin is a thermoplastic material used to make XPS foam boards, the foam boards can be melted and reused to produce new XPS insulation materials. More importantly, this is the common practice today. According to the Extruded Polystyrene Foam Association, XPS manufacturing plants do not generate "scrap" or waste, because 100% of industrial waste XPS foam boards are recycled, decomposed into resin materials and reused in the XPS foam manufacturing process.

XPS (Extruded Polystyrene) board is a waterproof and high compression board. With closed pores, thus requiring waterproofing, Huami offers extruded polystyrene (XPS) foam, a rigid foam that provides a strong, lightweight and flexible insulating solution that resists water absorption, making it a versatile Ideal for architectural and commercial applications. In addition to being impermeable to water, it is also a highly compressive sheet. It is very durable, so it is also used to insulate floors. On the first floor, the façade is often subject to various blows, such as children playing with a ball... As a solution, this type of slab combined with a vandal-resistant mesh is highly recommended to protect the cladding.


XPS Foam - Insulation

Expanded polystyrene, or XPS insulation for short, is a closed-cell insulation product commonly used in retrofit and new construction applications. Due to the manufacturing process, polystyrene board insulation is usually only available for standard-sized square or rectangular boards.
