[Abstract]:

1. Modified PVC tape
Modified PVC rubber strip: the price is relatively low, due to the different quality, low-end products due to the use of waste, substitute plasticizers and high filling amount, resulting in poor rubber strip elasticity, easy to hard, pungent smell, easy to use Migration makes the frame material yellow and has a short service life. Since PVC products contain halogens and heavy metals in stabilizers, it is not conducive to environmental protection. Therefore, foreign developed countries and domestic Beijing and coastal cities have eliminated or restricted the use of PVC strips.
2. Vulcanized EPDM sealing strip
The vulcanized EPDM rubber sealing strip is stronger than the PVC rubber strip in terms of sealing elasticity and durability. However, due to the need for microwave vulcanization line shaping, the processing energy consumption is high, usually more than 20 times that of PVC processing, and the product cannot be reused. , not environmentally friendly, not a product advocated by the state. Therefore, the basic door enterprises are not used.
3. Thermoplastic EPDM sealing strip
Thermoplastic EPDM rubber sealing strip This sealing strip is a new material developed on the basis of imported technology from abroad and domestic independent research and development in recent years. It is mainly used for automotive door and window sealing strips. In recent years, it has been used in building doors and windows sealing strip.
The outstanding advantages of thermoplastic EPDM seals are:
①The performance and service life are equivalent to the vulcanized EPDM rubber sealing strip.
②The processing energy consumption is lower than that of the vulcanized EPDM strip (equivalent to PVC).
③ It does not contain heavy metals such as halogen and lead, plus it can be recycled after several years, which meets the requirements of green building materials.
④The specific gravity is small (only 0.9-0.95) and the window rate is high. It seems that the purchase unit price is high, and the actual use cost is low. This product has developed rapidly in the use of building doors and windows in recent years.
Characteristics of high-quality door and window sealing strips
1. Light bulk density, high tensile strength, no water absorption (replacement of traditional three-linoleum four-felt, asphalt wood fir board and other materials). The product is environmentally friendly, easy to construct, and has good anti-seepage, anti-leakage and water-stop effects.
2. Corrosion resistance, aging resistance, high and low temperature resistance +80℃~-45℃, no flow, no deformation, no embrittlement, long service life.
3. It has an independent open-cell bubble structure, and the appearance of the special joint board is a honeycomb-like hole evenly distributed, which can be tightly bonded and integrated with the cement/sealant without roughening, adapting to changes in natural expansion and contraction, and enhancing the joints Seal expansion and water-stop effect.
