1. The price of modified PVC tape is relatively low. Due to the different quality, the price is generally between 6,000 yuan and 15,000 yuan / ton. Due to the use of waste materials, substitute plasticizers and high filling content for low-end products, the rubber seals
strips have poor elasticity, are easy to harden, have a pungent smell, are easy to migrate, make the frame material yellow, and have a short service life. A few door and window companies that are in low-level price competition are still using them. Medium and high-end PVC strips can meet the standard indicators and have a relatively long service life.  Since PVC products contain halogens and stabilizers contain heavy metals, 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. 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. Started to be used for building door and window seals. Its outstanding advantages 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). ③It 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 proportion 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. Product Features 1) Light bulk density, high tensile strength, non-absorbent (replacing 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. 3. The vulcanized EPDM rubber seals sealing strip is much stronger than the PVC rubber seals 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 the PVC processing, and the product cannot be Reuse, not environmentally friendly, is not a product advocated by the state. In addition, the proportion of materials of this type of products (above 1.4) is similar to that of PVC (the proportion of low-end vulcanized EPDM strips is larger), and the window rate is similar to that of PVC strips.
