Analyse de l'échelle de développement et du modèle de concurrence sur le marché mondial des bandes d'étanchéité en caoutchouc pour portes

Sealing strip refers to a sealing strip made of PVC or TPE material, which has functions such as dust prevention, sealing, sound insulation, and fixation. It is widely used in automobiles, machinery, doors and windows, and other places.

At present, the sealing strip market generally includes PVC strips, EPDM series, silicone rubber, and PPE/TPV plastic elastomer strips.

The manufacturing methods include extrusion molding continuous vulcanization, extrusion molding vulcanization tank vulcanization, or compression molding vulcanization.

By product type, EPDM sealing strips are currently the most important sub product, accounting for approximately 74.6% of the market share, with EPDM sealing strips dominating the market; Secondly, PVC sealing strips and TPE sealing strips together account for approximately 25.4% of the market share.

PVC strip

Modified PVC strip: The price is relatively low, but due to varying quality, low-end products use waste materials, substitute plasticizers, and high filling amounts, resulting in poor elasticity of the rubber strip, easy hardening, pungent odor, easy migration, yellowing of the frame material, and short service life. Due to the presence of halogens and heavy metals in stabilizers in PVC products, they are not conducive to environmental protection. Therefore, developed countries abroad and Beijing and coastal cities in China have phased out or restricted the use of PVC rubber strips.

Caoutchouc EPDM (Éthylène Propylène Diène Monomère)

EPDM rubber has good weather resistance and heat aging resistance, and can be used for a long time at -40 ° -120 ° C, achieving the same lifespan as doors and windows. Excellent ozone resistance and UV radiation protection. As a sealing material, it leaks outdoors and is not afraid of various weather conditions. Excellent comprehensive physical and mechanical properties, coupled with a scientifically reasonable formula, endow EPDM rubber strips with excellent elasticity, with a compression change of ≤ 23%, which is beneficial for various dynamic and static seals. This is something that other rubbers and plastics cannot achieve except for silicone rubber.

SILICON(silicone rubber strip)

PPE/TPV (plastic elastomer)

TPV is a dynamic sulfide of EPDM and PP: PPE and TPV both have the characteristics of silicone rubber, but the processing technology is relatively simple and can be processed using plastic molding equipment.

New opportunities for sealing strips in the real estate market and the development trend of the door and window industry

In recent years, with the continuous regulation of China's real estate market and the continuous upgrading of technology in the door and window industry, the development direction of sealing strips, as an important component of doors and windows, has attracted much attention. With the maturity of the real estate market, the proportion of refined decoration market has been increasing year by year. According to relevant data, the rapid development of the fine decoration market has driven the demand for high-quality doors and windows, thereby bringing new growth space to the sealing strip market.

With the development of door and window technology, system doors and windows have gradually become the mainstream in the market. System doors and windows have higher requirements for sealing performance, sound insulation performance, thermal insulation performance, etc. As a key component, the performance of sealing strips directly affects the overall performance of doors and windows. At the same time, consumers' aesthetic demands for doors and windows are becoming increasingly diverse, and the personalized and customized door and window market is rapidly rising. To meet market demand, sealant companies need to constantly innovate and develop more products with unique performance and aesthetic appeal.

Under the development trend of the real estate market and the door and window industry, the sealing strip industry is facing new opportunities and challenges.

Suzhou Midtech Machinery Co., Ltd., as a benchmark source factory in the plastic extrusion machinery industry, produces sealing strip production equipment that can produce personalized and customized sealing strip products according to customer requirements.

The plastic machinery and PVC sealing strip extruder we manufacture are suitable for various industries, such as automobiles, doors and windows, cabinets, refrigerators, containers, etc., and have a wide range of application scenarios.

Advantages of Midtech devices:

1. High precision and energy-saving: The PVC sealing strip equipment adopts a single screw extruder with high-precision hard chrome coated mirror treated alloy screws, intelligent temperature controller, and silent fan forced air cooling, with a temperature accuracy of up to 1 ℃. The driving motor adopts variable frequency control.

2. Easy to operate: The device has a simple structure and is easy to operate. For example, the cooling and shaping water tank is made of stainless steel material, and the three-dimensional adjustment of the water tank frame makes operation more convenient.

3. Stable performance: PVC sealing strip equipment has stable performance and can meet customers' customized needs. For example, the belt traction machine adopts surface polyurethane foam multi wedge belt, which is wear-resistant and can effectively provide traction force to ensure that the product can achieve continuous and stable traction without pressure change.

4. Flexibility: Our equipment can easily switch extrusion molds according to the different shapes of aluminum profile silicone sealing strips, making it easy to achieve product conversion.

For sealing strips, there are two production processes: extrusion molding and compression molding. Different product sizes and performance requirements require different processing techniques.

Plastic extruder extrusion processing is a relatively stable production process. The mixed rubber material is placed into the extruder feed inlet, heated and melted by the rotation of the screw, and pushed to the mold mouth. The required shape and size of the sealing strip are set inside the mold, and the rubber material after high temperature and high pressure can be molded in one go. Compared to other manufacturing processes, extrusion technology has the advantages of high manufacturing accuracy, beautiful appearance, and high production efficiency.

After extrusion molding, the sealing strip can also be customized for subsequent processing, such as automatic cutting, surface spraying, and bottom back adhesive. With the improvement of technology, extrusion technology can now achieve double composite, triple composite co extrusion technology, composite extrusion of hard and soft adhesives, metal skeleton and rubber materials, or co extrusion technology of different types of adhesives, materials, and colors of rubber materials.

En conclusion :

In the future, we will keep up with the market pace and constantly innovate to meet the constantly upgrading market demand. Welcome friends from related industries to provide suggestions and assistance for the future common development of our industry.
