Do you know the types of “insulation materials”?

What are the insulation boards, extrusion plates, EPS, XPS, polyurethane plate, phenolic plate, rock wool plate, glass wool plate, and rubber plates, what are the use, what do you know?

Insulation plate (including extrusion plate, polyurethane plate, phenolic plate, glass wool plate, rock wool plate, etc.)

The presence of the thermal insulation board is easy to understand the board for the insulation of the building. Including squeeze plates, polyurethane plates, etc. made of insulation materials.

Polystyrene (abbreviated PS)


PS is synthesized by the styrene monomer through free radicals. It is a colorless and transparent thermoplastic plastic, which has a glass conversion temperature higher than 100 ° C. Therefore, it is often used to make disposable containers that need to bear the temperature of boiling water, as well as disposable foam lunch boxes, building insulation materials, etc.

EPS (also known as foam plate, polystyrene foam plate, benzene, polybenzene plate)

The EPS board is a hair beads containing volatile liquid foaming agents. After heating, it is heated in the mold and heated in the mold. When buying a computer, the white foam used for packaging is EPS.

XPS (also known as extruded polystyrary board, extrusion plate)


The full name of squeezing polystyrene board is squeezing polystyrene foam plate, referred to as extruded plates, also known as XPS plate, and squeezed polybenzene board. It is a hard foam plastic plate made by the polystyrene resin as the raw material plus other raw and auxiliary materials and polymers, and then squeezed out the mold. Plastic polystyrene foam plastics (referred to as XPS), XPS has a perfect closed honeycomb structure. This structure makes the XPS board very low water absorption (almost no water), low thermal guide coefficient, high compressive, anti -aging resistance (Normally use almost no aging decomposition), which is a special material for floor heating preservation layers. The picture shows green feathers environmentally friendly extrusion plates.

Small knowledge: Polyetylene foam plastic is divided into two types: expansion EPS and continuous extruded XPS. Compared with EPS board, XPS board is the third -generation hard foam insulation material. The production process has the superior performance of EPS boards that cannot be replaced.

Polyurethan (PU or PUR)

Polyurethane is a type of polymer that contains aurtile -type duplicate structure units in the macromolecular chain, which is called polypeamate. PU is a product reflected in a certain proportion by polycisienate and polyether or polyester. Polyurethane plate refers to a polyurethane clamping plate made of PU or composite PU and color steel plates. It is mainly used for an external insulation system for industrial and civilian buildings.

Phenolic Foam Board

The phenolic plate is made of phenolic foam material. The phenolic foam material is a high -molecular organic hard aluminum foil foam product. The phenolic insulation board is widely used in developed countries.

Rock wool board

It is an inorganic fiber board made of basalt as its main raw material and is processed by high temperature melt. Generally used for exterior wall insulation.

Glass wool

The glass wool is fibrilized after melting the glass, and the glass wool roll felt product made by adding a bonding agent is added. The diameter of the glass wool fiber depends on the centrifugal squeezing technology. The glass wool plate is used in thermal insulation, heat insulation, sound absorption, noise reduction of the exterior wall of the building, the heat insulation of the industrial kiln; the mezzanine of the steel heating plate.

Rubber Slab; Rubber Sheet)

The rubber sheet uses rubber as the main material (which can contain enhanced materials such as fabrics, metal plates and other enhanced materials). It is made of a certain thickness and large area of ​​sheets, referred to as rubber plates. The rubber sheet has high hardness, the physical and mechanical properties are average, and it can work in air with little pressure and the temperature of 20 ° ~+140 ° C. The rubber plate is composed or squeezed by the mixed glue periodic periodic sticker, and it is made of sulfide with a tablet sulfide or continuously vulcanized with a drum vulcanizer. Color: black, gray, green, blue, etc. It is widely used in industrial and mining enterprises, transportation departments and houses. Used as a sealing ring, rubber pad, doors and windows sealing and laying workbench and floor.


Rubber and Plastic

Rubber and plastic is the collective name of the rubber and plastic industry. They are all subsidiary products of petroleum. They are the same in the source. Wide is tires. Plastics are becoming more and more widely used with the demand and use of the market, and it is inseparable from daily life.

The harm of inferior squeeze plates -toxic

Floor warmth has become popular among more and more urban families today, but when ordinary families are installed with floor heating, they often only let the floor warm company or decoration master report a general offer to see what brand of boilers, what brand of pipes, and another price. The rest no longer care about him. As everyone knows, in addition to the main materials such as the boilers, pipes and other main materials that people are most concerned about, the quality of supplementary materials such as extrusion plates that people are most ignored are not only about whether energy saving and environmental protection, but also human health.

The root cause of “poison”: recycling plastic supplementary materials

There is no national standard at present in the domestic presence of thermal supplementary materials. Many materials have not done well in terms of environmental protection. Many owners have chosen the “three -none” ground heating auxiliary materials that may be harmful to the human body because of their lack of professional knowledge, but they are still unknown. He mentioned that 90%of the domestic heating auxiliary materials in China are used for recycling, and the recycling of plastic is conducive to the environment in itself. However, due to the current domestic recycling plastics, there are still supervision loopholes, medical waste, foreign garbage, and harmful plastic may enter the recycling and recovery link of plastic. In addition, the current level of domestic plastic recycling enterprises is low. Most companies still stay in small workshops. state. It is incapable to distinguish which plastics are toxic and which are not recycled and recycled. As a result, many land heating auxiliary materials such as extruded plates are large and overwhelmed. These auxiliary materials made of recycling materials are becoming the “invisible killer” of the “sneak attack” owner.

Polyethylene: Can cause chronic poisoning of the human body

It is understood that PVC, also known as PVC, is not toxic itself, but due to the heating of the ground, as long as the temperature is close to 50 degrees, it will produce carcinogens such as hydrogen chloride, toxic gas, and hydrochloric acid, dual villain hydrochloric acid, and dual villain. The release of these substances is released. It will have a strong stimulating effect on human eyes and respiratory mucosa. Light can cause symptoms such as headache, nausea, allergies, and severe cases can cause damage to human liver and nervous system, which is very harmful to human health.

Insufficient cognitive: “Three None” ground heating auxiliary materials are the main cause of rampant materials

At present, the health hazards that may be possible for the “three non -” auxiliary materials. In addition to the professionals in the industry, the ordinary home improvement owners basically know very little. In fact, as far as the market price is concerned, there are quality -guaranteed and safer branded heating auxiliary materials. Compared with the “Three None” auxiliary materials, the energy conservation is 15%for the time being, and the price is only less than 10%higher. For a house of 200 square meters, only one or two thousand yuan is invested at one time. Generally, the owners can bear the economy, so the price factor is not a problem. Why does the “poisoning” ground heating auxiliary material involved in the “poison” and ground heating auxiliary materials are now popular, the main reason is that the owner’s lack of professional knowledge of the ground heating and some ground heating installation companies often use the “three none of the three -nothing” on the ground heating auxiliary material according to the customer’s “prices” requirements. “Auxiliary materials, in fact,” Three None “auxiliary materials, the ultimate harm is the consumer’s own interests. It seems to have” benefits “. In fact, it is very much to lose, because the purpose of installing the floor is for the comfort of the family, but because of the greed of” “Affordable” is endangering family health.
