In aluminum alloy doors and windows, the sliding window looks at the top strip, and the casement window looks at the rubber strip. It can be seen that the position of the sealing strip in the casement window cannot be underestimated.

Sealing strip: Don't look at the small strip, it plays a vital role in the performance of doors and windows, and the requirements for it are also very high. It needs to have the functions of waterproof, sealing, energy saving, dustproof, The functions of heat preservation and heat insulation must have strong tensile strength, good resilience, and good heat resistance and aging resistance.

At present, the market of sealing strips is mixed, and the market is generally dominated by modified PVC, vulcanized EPDM rubber sealing strips and thermoplastic EPDM/PP rubber strips. So what's the difference between these three tapes? Which is the better choice?

Modified PVC sealant strip: The price is lower, but the quality is different. The use of low-end waste materials to replace plasticizers and high filling content makes the rubber strip easy to harden, migrate, have poor elasticity, and have a pungent odor, which greatly reduces the service life. In addition, because PVC contains halogens and heavy metals, which violates the green environmental protection advocated by the state, the high-end market has eliminated or restricted the use of PVC strips.

Thermoplastic EPDM and thermoplastic EPDM composite door and window sealing strips: It is a new material introduced from abroad in recent years and developed on the basis of domestic independent research and development. It is widely used in high-tech fields such as automobiles, railways, and shipping. In recent years, it has gradually been used in the building door and window industry, and it is a sealing material with excellent performance.

Tegood's windows all use EPDM tape, which has better heat resistance and aging resistance, which can make our windows have better waterproof and sealing properties.
