What are the main characteristics of cabinet sealing strips? Below is an introduction for everyone.
1. Modified polyvinyl chloride tape. The price is relatively low, and due to different quality, the price is generally between 6000 yuan and 15000 yuan/ton. Low end products, due to the use of waste materials, alternative plasticizers, large filling amounts, poor elasticity of the adhesive strip, easy hardening, pungent odor, and easy migration, make the frame material yellow and have a short service life. A few door and window enterprises that compete at low prices are still using them, and the middle end PVC tape can meet the standard indicators, with a relatively longer service life, Because PVC products contain halogens and stabilizers contain heavy metals, which are not conducive to environmental protection, developed countries abroad and coastal cities in Beijing and China have phased out or restricted the use of PVC tape.
2. Thermoplastic EPDM rubber sealing strip. This 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, and in recent years, it has been used for building door and window sealing strips. Its outstanding advantages are that its performance and service life are comparable to those of vulcanized EPDM sealing strips, its processing energy consumption is lower than that of vulcanized EPDM tape (equivalent to PVC), it does not contain heavy metals such as halogens and lead, and can be recycled after several years, meeting the requirements of green building materials. Its proportion is small (only 0.9-0.95), and its window opening rate is high. It appears to have a high purchase price, but the actual use cost is low. Product characteristics. 1) This product has light bulk density, high expansion strength, and does not absorb water (instead of traditional materials such as three oil four felt, asphalt wood fir board, etc.). It is environmentally friendly, easy to construct, and has good anti-seepage, leak prevention, and water sealing effects. 2) Corrosion resistance, aging resistance, high and low temperature resistance, 80~-45, non flowing, non deformation, non embrittlement, and long service life. 3) With an open bubble structure, the specially designed joint plate has a honeycomb shaped appearance, with evenly distributed holes, and can be tightly bonded with cement/sealant without the need for sanding to adapt to natural expansion and contraction changes, enhancing the sealing, expansion, and water sealing effects of the joint.
3. Vulcanized EPDM rubber sealing strip. Compared with PVC tape, the sealing elasticity and durability are greatly enhanced. However, due to the need for microwave curing lines, the processing energy consumption is usually more than 20 times that of PVC processing. The product cannot be reused, is not environmentally friendly, and is not a product advocated by the state. In addition, the material proportion of this type of product (above 1.4) is equivalent to PVC (with a higher proportion of low-end vulcanized EPDM tape), the window opening rate is similar to PVC tape, and the use cost is relatively high, It is difficult for door and window enterprises to accept.
