EPDM is a copolymer of ethylene, propylene and a few third monomers non-conjugated diene. It is named in the world: Ethyiene Propyene Diene Methyiene EPDM for short. It has outstanding UV resistance, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical medium resistance, water resistance, good electrical insulation and elasticity, and other physical and mechanical properties. These advantages are incomparable to PVC and other materials.

In the 1980 s, EPDM sealing strips were introduced into China, which brought great convenience to people's lives. The production process of sealing strips has been greatly developed. In the long-term accumulation, sealing strips It has been applied to various industries such as automobiles, doors and windows, home appliances, and its composition and production process are also different according to the different requirements of various industries. The development of various industries has driven the development of the sealing strip to varying degrees, and it also provides essential materials for the development of various related industries. The development history of the sealing strip is closely related to the development of the door and window industry. The renewal of the two maintains almost the same rhythm, with development and progress.
With the progress of EPDM sealing strip technology and production materials, more and more sealing strip products have been born. Sponge foam sealing strip is one of them. Compared with the rubber sealing strip of our manufacturer, its advantage is very obvious. First of all, in terms of sealing effect, this kind of sealing strip has the advantages of softness, elasticity and good effect, so it can handle the details in the sealing. There is also a sponge foam sealing strip of lighter texture, chemical stability, so applicable to any place of the seal, the price of foam sealing strip is not fixed, because its development is not mature, so whether it is in technology or the market needs to be further improved.
At present, the main factor affecting its price is its production materials, because the raw materials of various sponge foam sealing strips are different, so the sealing strips produced are also different in quality. And with the progress of technology will be more and more sponge foam sealing strip was born, in addition to the production efficiency is also an important factor affecting its price, because at present its technology in product production has not reached the point of matching with rubber sealing strip products, which is also an important reason affecting its price and market.
