With the improvement of people's living standards, the standards for living conditions are also increasing. Rubber door and window seals are not only suitable for cars, trains, and machinery, but also widely used in doors and windows. Sealing strips play a crucial role in wooden doors, anti-theft doors, sliding doors, various aluminum-plastic doors and windows, and other doors and windows. The most obvious thing is shock resistance. After installing it on the door stop line, it reduces (or even disappears) the collision sound when closing the door (window), protects the edge of the door leaf, extends the life of the door, reduces noise, and secondly, seals, absorbs shock, isolates indoor and outdoor air, effectively playing a role in insulation and energy saving, and prevents mosquitoes and other small insects from entering the room.

The brutal growth and vicious competition of rubber door and window sealing strip enterprises have brought great negative impacts to the rubber and plastic industry, and industry users and media have begun to question the actual effectiveness of rubber foam sealing strips. From the original advocacy to caution, there has been a slowdown in market sales growth and even a decline in sales in some regions. While domestic rubber foam sealing strip enterprises are facing difficulties, foreign rubber foam sealing strip brands have secretly entered the Chinese market. Of course, despite the chaotic state of the market, major domestic brands are exploring and gradually finding their own development direction. Foam sealing strip is a type of sealing strip that uses the characteristics of certain materials to create pores inside through processing. It is divided into EPDM foam sealing strip, silicone foam sealing strip, and PU foam sealing strip. The foam sealing strip is formed in one step using microwave vulcanization technology, with a clean and beautiful surface, no contact marks, outstanding elasticity and anti compression deformation, and excellent aging resistance. Excellent flame retardant function, low smoke and low toxicity; The product has stable functions and high dimensional accuracy.

With the advancement of sealing strip technology and manufacturing materials, more and more sealing strip products have been born, and rubber sealing strips are one of them. Compared with our manufacturer's rubber sealing strips, its advantages are very obvious. Firstly, in terms of sealing effect, this type of sealing strip has advantages such as softness and good elasticity, which allows for attention to detail in sealing. Additionally, the sponge foam sealing strip has a lighter texture and stable chemical properties, making it suitable for sealing anywhere. The price of foam sealing strips is not fixed for sponge foam sealing strips because their development is not yet mature, so they need further improvement in both technology and market.
