In life, door and window seals are a permanent household product.
It is needed for everything from doors and Windows to cars.
What kind of material are we using?
How to tell the good ones from the bad ones?
What's inferior?
Next, I will introduce to you!
The first vulcanized epdm seal strip.
In terms of sealing, elasticity and durability, it is stronger than PVC rubber strip, but due to the need for microwave vulcanization line shaping, high processing energy consumption, usually more than 20 times of PVC processing and high cost, and the product cannot be recycled, not environmental protection, not the product advocated by the country.
So basic businesses don't use them.
The second modified PVC strip.
The price is relatively low, because quality actor bad differ, low-end product because of use scrap, substitute plasticizer and high fill quantity, such glue is poor in elasticity, easy to send hard, have excitant odour, make frame makings hair yellow easily, service life is shorter.
In general, it is not recommended.
The third thermoplastic epdm seal strip.
Thermoplastic epdm sealing strip is a new material developed in recent years on the basis of the introduction of foreign technology and independent research and development in China.
Its main advantages are: performance and service life and vulcanized epdm rubber seal strip equivalent;
It does not contain heavy metals such as halogen and lead, and it can be recycled after several years, which meets the requirements of green building materials.
Long service life.
It seems that the purchase price is high and the actual use cost is low.
This kind of product gets very rapid development on building door window use in recent years.
