Polyurethane sealant is widely used in construction. First of all, it can be used to seal the exterior walls, ceilings and floors of buildings. Polyurethane sealant can fill the gap between building materials, prevent moisture, air and dust from entering the interior of the building, and improve the sealing and sound insulation of the building.

Secondly, polyurethane sealant can be used for the installation of doors and windows. It can fill the gap between the door and window frame and the wall to achieve a sealing effect, prevent cold wind, rain and noise from penetrating into the room, and improve indoor comfort.

In addition, polyurethane sealant can also be used for the manufacture and decoration of indoor furniture. It can glue wood, plastic and metal parts of furniture to provide strong connections and increase the stability and durability of furniture.

In short, polyurethane sealants play an important role in sealing, waterproofing, sound insulation and connection in buildings, improving the quality and performance of buildings. It is widely used in the construction industry to create a more comfortable, safe and reliable living and working environment for people.

First of all, the door seal, the purpose is to make everyone's life more comfortable, but once the use of inferior sealing strip, not only no comfort, but also to our living environment and family members of the health threat. Therefore, it is imperative to buy environmentally friendly sealing strips. The original general use of the material of the sealing strip is mainly PVC material and silicone rubber, but because these two materials are not very environmentally friendly, it has been basically eliminated. Now the most used folding door sliding door sealing strip material is mainly I-ECO coated type. Its physical properties are relatively stable, and it is also resistant to high temperature and cold. More importantly, such a sealing strip has very good environmental performance and will not pose a threat to our daily life. But said the ability to adapt to environmental changes is very strong, such a folding door sliding door in the use of time we are also more at ease.

To sum up, when we buy the door, we must not ignore the problem of the sealing strip, and whether the sealing strip can meet the environmental protection standard is also one of the factors to test whether the door is of high quality. Only high-quality and environmentally friendly doors can make us safer to use.

The following points should be paid attention to when selecting door and window sealing strips:

1. Material: The material of the door and window sealing strip is very important for the sealing effect and durability. Common materials are silicone, rubber and plastic. Silicone has good weather resistance and high temperature resistance, suitable for outdoor doors and windows; rubber material has good elasticity and wear resistance, suitable for frequent switching of doors and windows; plastic sealing strip is suitable for ordinary indoor doors and windows.

2. Size: When selecting the sealing strip, the required length and width should be determined according to the size of the door and window and the size of the gap. A wider sealing strip can provide a better sealing effect, but it will also increase the resistance of opening and closing doors and windows.

3. Applicable scene: Different doors and windows may be different in material and structure, so it is necessary to choose a sealing strip suitable for this type of door and window. For example, the shape and size of the sealing strips of sliding doors and flat doors may be different.

4. Sealing performance: The main function of the sealing strip is to prevent the penetration of air, water and noise. Therefore, attention should be paid to the sealing performance of the sealing strip, such as compression resistance, weather resistance and waterproof performance.

5. Installation convenience: When choosing door and window sealing strips, the convenience of installation should be considered. Some sealing strips are self-adhesive and easy to install, while others need to be fixed with glue or screws.

In short, the selection of door and window sealing strip needs to comprehensively consider factors such as material, size, applicable scene, sealing performance and installation convenience, so as to ensure the selection of sealing strip suitable for doors and windows and improve the sealing performance and service life of doors and windows.

EPDM rubber strip is a kind of rubber strip made of polymer material, which has the following advantages:

1. Strong weather resistance: EPDM rubber strip has good weather resistance and can keep its physical properties unchanged under extreme weather conditions. It can resist the erosion of ultraviolet rays, high temperature, cold, air pollution and other factors, and will not age and deteriorate due to long-term use.

2. Good chemical resistance: EPDM rubber strip has excellent chemical resistance and can withstand the erosion of various acids, alkalis, salts and various solvents. This allows it to maintain stable performance in different environments without being damaged by chemicals.

3. Good sealing: EPDM rubber strip has good elasticity and resilience, which can closely fit the sealed surface and provide a good sealing effect. It can effectively prevent the penetration of water, gas, dust and other substances, and protect the interior of equipment and buildings from the external environment.

4. Strong heat resistance: EPDM rubber strip has good heat resistance and can maintain its stable performance under high temperature environment. It will not soften, melt or deform due to high temperature, and can maintain its original physical properties for a long time.

5. Good aging resistance: EPDM rubber strip has a long service life and can withstand long-term use and frequent deformation without aging, cracking and fracture. This reduces the frequency of maintenance and replacement, reducing maintenance costs.

In short, EPDM adhesive tape has the advantages of strong weather resistance, good chemical resistance, good sealing, strong heat resistance and good aging resistance, which makes it widely used in sealing and protection applications in various industries.

EPDM sealing strip is a kind of sealing material widely used in construction, machinery, electronics, automobiles and other fields. It is made of EPDM rubber and has the following advantages:

1. High temperature resistance: EPDM sealing strip can be used for a long time in high temperature environment, and its heat resistance is better than that of ordinary rubber sealing materials. Under high temperature conditions, the EPDM sealing strip will not deform, soften or produce odor, and maintain good sealing performance.

2. Weather resistance: EPDM sealing strip has good weather resistance and can withstand the erosion of harsh environments such as ultraviolet rays, ozone, oxygen and acid rain. It will not age, harden or crack due to long-term exposure to the outdoors, and maintain a long service life.

3. Chemical corrosion resistance: EPDM sealing strip has excellent chemical corrosion resistance and can resist the erosion of various chemical substances, such as acid, alkali, solvent, etc. It will not expand, dissolve or deteriorate due to contact with chemical substances, and maintain a better sealing effect.

4. Good mechanical properties: EPDM sealing strip has good elasticity and tensile properties, and can adapt to different deformations and movements. It can maintain a uniform sealing pressure under different temperatures and pressures to prevent the leakage of liquid, gas and dust.

5. Wear resistance: EPDM sealing strip has high wear resistance, which can effectively reduce the wear of sealing materials caused by mechanical movement and friction. It can be used for a long time under the conditions of high-speed rotation, reciprocating motion and frictional contact, and maintain a long service life.

6. Environmental performance: EPDM sealing strip is an environmentally friendly sealing material, does not contain harmful substances, and will not cause pollution to the human body and the environment. It can be used safely in food, medicine and other fields, and meets the requirements of health and environmental protection.

In summary, EPDM sealing strip has the advantages of high temperature resistance, weather resistance, chemical corrosion resistance, good mechanical properties, wear resistance and environmental protection. It is widely used in various fields to provide reliable sealing protection for products.
