Main characteristics of sealing strip

The price is relatively low, because the quality is different, the price is generally between 6000 yuan / 15000 yuan / ton. Low end products, due to the use of waste, substitute plasticizer and high filling capacity, to the rubber strip elasticity is poor, easy to hard, there is nose smell, easy migration, so that the frame material yellow, short service life. A few doors and windows enterprises in low price competition are still in use. Medium and high-end PVC glue can reach the standard indicators, and the service life is relatively long.

Because PVC products contain halogen, the stabilizer contains heavy metals, so it is not conducive to environmental protection, so foreign developed countries and domestic Beijing and coastal cities have eliminated or restricted the use of PVC glue strip.

    2. thermoplastic three yuan EPDM sealing strip

The sealing strip is a new material developed on the basis of imported technology and domestic independent research and development in recent years. It is mainly used in automobile door and window sealing strip. It has been used in building door and window sealing strip in recent years. It has outstanding advantages:

Performance and service life are equivalent to vulcanized three EPDM sealing strip.

The processing energy consumption is lower than that of vulcanized three yuan ethylene propylene rubber strip (equivalent to PVC).

    3. Heavy metals such as halogen and lead are not available, and can be recycled after several years, which meets the requirements of green building materials.

    4. small proportion (only 0.9 - 0.95), high window output rate. It seems that the purchasing unit price is high and the actual use cost is low.
