Doors and windows are indispensable decorative materials in interior decoration design. When selecting and purchasing interior doors and windows products, many owners often only focus on the appearance and quality of doors and windows, but rarely pay attention to the purchase of accessories for door and window installation, especially door and window sealing strips. Door and window sealing strips determine the installation quality and performance of doors and windows to a certain extent. Which material is better for door and window sealing strips? How to choose door and window sealing strips? Let's follow the editor to find out.

门窗密封条哪种材质好：

　1. Rubber:

　Door and window seals are still widely used in door and window decoration, and their durability is still quite good. The rubber material is good, relatively soft, and can help to block impact well. Its compression resistance and impact resistance are very good. As the main rubber material now, it can have a good sealing effect and extend its service life.

　2、PVC材质：

　When it comes to door and window seals, PVC material is actually a pretty good choice. From the current selection of many materials, PVC material has won the favor and liking of users due to its stable use and good material performance. Even if it is used for a long time, it will not appear yellow. It has become a more classic material representative now, and its comfort is also very good.

　3. TPV material:

　The overall elasticity of TPV materials is still good. Considering the current needs of home life, it has also achieved good design and development, with guaranteed quality and very good use effect. With the development of today's technology, TPV materials have also achieved many new improvements, with greatly improved performance and guaranteed stability.

4、硅胶：

　When it comes to door and window seals, silicone is also an indispensable choice. The elasticity and heat resistance of silicone materials are obvious to all. Its own plasticity is good, and it has won more and more users' favor and liking. Silicone materials are relatively safe and have relatively stable performance, which has won the praise of many users.

5、三元乙丙：

　EPDM may not be very familiar to everyone, and it is actually used more in door and window sealing strips. EPDM is also a very good choice. EPDM is a material that has been fully designed and coordinated, with good texture and sealing effect. It is also very good, and it is becoming more and more popular in today's decoration. In the actual decoration design, you can first have a basic understanding of whether it meets today's decoration needs.

　The above is a brief introduction to the common materials of door and window seals. I believe that after the above introduction, everyone will have a further understanding and understanding of door and window seals. As for which material of door and window seals is good, everyone's preferences are different. It is recommended that you choose according to your own preferences. Of course, in the process of selecting door and window seals, you must pay attention to identifying the quality of door and window seals. Let's take a look at the following introduction:

门窗密封条如何挑选：

　1. Determine the size of the sealing strip to avoid it being too long or too short, or if the height and width of the sealing strip are inconsistent with the size of the outer frame of the door and window.

　2. Select the appropriate type of sealing strip and determine the type of sealing strip that needs to be purchased, including type I, type D, type E, etc., to avoid the purchased sealing strip from being installed and used.

　3. Select the material of the sealing strip, and determine the material of the sealing strip according to different usage environments, characteristics, functions, etc. For example, the EPDM sealing strip is mainly used for sealing in high-temperature water vapor environments. In short, the material of the sealing strip is selected according to the usage status of doors and windows.

　4. Inspection of the sealing strip. When selecting the door and window sealing strip, it is necessary to observe whether there are obvious cracks on the sealing strip, whether it is uneven, etc. It is required that the surface of the sealing strip be clean, free of scratches, bumps, rust, smooth, uniform thickness, and no pores.

　5. The quality of the sealing strip can be determined from five aspects:

　(1), hand tear:

　Take a sealing strip and tear it at its thinnest part. The greater the force, the higher the glue content, which means that the comprehensive performance of the sealing strip is very good. You can consider purchasing it.

　(2), hand pull:

　Holding the sealing strip in your hands, two people each end, like pulling a rope to both ends, first to see if it can be broken, and then to see if it can rebound to the original length, the better the elasticity of the sealing strip, indicating that the seal strip will not be deformed due to the long-term closing pressure of the door after installation.

　(3), scrape the sealing strip with your fingernails:

　The surface of the sealing strip with poor material and low glue content is easy to be scratched white. After this kind of sealing strip is installed on the door, as long as there is a hard object collision or slight scratch, it will cause the sealing strip to "break the image", which is very unsightly.

　(4) Intuitive observation of the sealing strip:

　It is to see if the brightness of the cross-sectional joint of the sealing strip is close to the surface color of the sealing strip. If it is close, it means that the filler contained in the sealing strip material is not much, and it can be purchased.

　(5) Smell the smell of the sealing strip through your nose:

　If the sealing strip has an odor or a plastic odor, then the sealing strip is not suitable for use on wooden doors. A standard sealing strip should be odorless or have a hint of natural rubber.

　6. The quality of the sealing strip material:

　Wrap the sealing strip as tightly as possible on the profile, place it at high temperature for a period of time (placed on the roof or in a sunny place), observe whether the surface of the profile and the contact surface of the sealing strip are stained and discolored, and whether the dust on the surface of the sealing strip is yellow (if there is oil on the surface of the sealing strip, it is easy to absorb soil). Oil seepage, whether it is stained with dirty hands, the surface of the sealing strip with excellent material is smooth, dustproof, oil-resistant, high-temperature resistant, etc. It will not appear under high temperature irradiation. Yellowing, oil leakage, dirty hands, etc.

　7. Weigh the sealing strip of the same material:

　If the same amount of sealing strip is made of good material, the weight is light. Adding talcum powder, heavy calcium, etc. to the sealing strip to increase the weight of the product is much heavier than the regular addition of light calcium carbonate, and it is priced by weight in the sales of the sealing strip. Therefore, when selecting the sealing strip, the proportion of the same material and type of sealing strip should be carried out.

　The above is a brief introduction to which material is better for door and window seals and how to choose them. I hope it will be helpful to everyone.
