What Is The Insulation Material Extruded Xps Foam Board And How To Identify The Advantages And Disadvantages

What is insulation material extruded plastic board

The full name of the insulation material extrusion board is called insulation extruded polystyrene foam board, referred to as XPS board, it is polystyrene as raw material, through the polymer after high temperature and the role of the catalyst, extrusion of continuous closed-cell foam type rigid plastic foam board.

Advantages of insulation material extruded plastic board

①Heat insulation

Thermal insulation materials extruded plastic board has a high thermal resistance, low linear, low expansion ratio. It is also because of this structural characteristics, so that the closed cell rate of up to 99% or more, and its honeycomb bubble structure, to a great extent, to avoid the heat dissipation phenomenon caused by air circulation, to ensure that the thermal insulation of the long term effective and stable.

Compression resistance

Due to the special structure of the extruded plastic board, it has high compressive strength and strong impact resistance. According to different models and thickness of the XPS board, its compressive strength is as high as 150-500KPA or more, basically can withstand a variety of system load, so it is widely used in the field of geothermal Gongzheng, airport runway, highway and car interior decorative insulation.

Waterproof and moisture-proof

The water absorption rate of XPS board is extremely low and decreases with the decrease of heat preservation performance. In the case of low temperature, the non-absorbent property makes the water can not penetrate into the interior, and protects the internal structure of the insulation material well. Therefore, XPS boards can cope with extreme weather problems and well solve the problems of water leakage, infiltration and icing lights.

④Light texture

The insulation material extruded plastic board adopts a completely closed-cell foam structure, which is somewhat similar to honeycomb. Therefore, it has a super-light weight and high strength. Whether in construction or transport, it is not easy to break, cutting up the efficiency *, not drag, and installation and operation is very convenient, by many projects like.

How to identify the advantages and disadvantages of extrusion board

● Look at the colour

Extruded boards that are 100% new are white in colour. Extruded boards on the market will also add some colour masterbatch for different colours. It can be said that the more positive the colour, the better, the higher the saturation, the better; on the contrary, those poor-quality extruded plastic board colour is grey, black, dark colour.

Smell

Extruded plastic board is easy to break, we can identify by smell. Good quality extruded plastic board after a period of air replacement, after breaking basically no smell. If it is recycled and reprocessed, some environmental agents will be added, and then has a pungent odour.

● Look at the pressing effect

Extruded plastic boards are often used for underfloor heating, basements, roadbed insulation, etc., and have high requirements for their compressive strength. If it is used for underfloor heating, the compression strength should be at least 200KPA or more; if it is used for roads, the compression strength should be at least 250-300KPA or more. Household housing decoration, used in roofing, wall insulation, the requirements will not be so high. When choosing, be sure to choose according to the purpose of use.

● Look at the combustion performance

The combustion level of extruded plastic board is divided into B1, B2, B3, B1: flame retardant, B2: combustible, B3: flammable. The flame retardant extruded plastic board is the XPS board based on the addition of flame retardants. For home improvement friends, * of course, or B1 grade, so that more safety and security.

● Look at the brand

Different brands have different product quality and different overall characteristics. Everyone in the choice, must have some screening, high school and low grade, really penny a penny.
