Broken Bridge Aluminum Window, Using Which Kind Of Weather Stripping?
Jul 17, 2017

 

Now More customer choose broken bridge aluminum window, but we often focus on the price, and at the same time neglect some auxiliary materials, such as aluminum window weather stripping, this directly affects the window sealing effect and service life.

The poor quality of the broken bridge aluminum strip has pungent taste, strip rolling, a long time will be shortened, directly reach the sealing effect, the current market in general the aluminum manufacturers are using three EPDM rubber strips, because the rubber strip is a little better than the poor, but also than a TPE strip three, EPDM rubber strip gloss is not very good, but in the sun will have a little taste Now choose more and more broken bridge aluminum window, but we often focus on the price at the same time easily and some auxiliary materials, such as aluminum window sealant, this directly affects the window sealing effect and service life.

The poor quality of the broken bridge aluminum strip has pungent taste, strip rolling, a long time will be shortened, directly reach the sealing effect, the current market in general the aluminum manufacturers are using three EPDM rubber strips, because the rubber strip is a little better than the poor, but also than a TPE strip three, EPDM rubber strip gloss is not very good, but it will have a little taste in the sun.

And quality of the broken bridge aluminum window rubber strip for TPE strip, the market price of three yuan more than the ethylene propylene rubber per kilogram twice as expensive, environmentally friendly non-toxic TPE strip, so that consumers have more confidence, TPE materials do not contain lead, mercury and cadmium, antimony and other heavy metals, toxic plasticizer phthalate two formic acid ester.

On the market, the broken bridge aluminum window adhesive tape mainly has the following several kinds:

1. modified PVC adhesive tape

The price is relatively low, because the quality is different, the price is generally between 6000 RMB to 15000 RMB/ ton. Low end products, due to the use of waste materials, alternative plasticizers and high filling capacity, to make the rubber strip elasticity is poor, easy to hard, there is nose odor, easy migration, so that the frame material yellow, and short service life. A small number of low price competition in the doors and windows enterprises are still in use.

Because PVC products contain halogen, the stabilizer contains heavy metals, so 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 glue strip.

2. vulcanization EPDM rubber sealing strip

The elastic sealing durability greatly strengthened than PVC strip, but due to the microwave vulcanization line shape, high energy consumption, usually is 20 times more than PVC processing, products can not reuse, not environmental protection, not national advocacy products. In addition, this kind of product material proportion (above 1.4) and PVC class is quite (low end vulcanization three yuan, ethylene propylene rubber strip proportion is bigger), the window rate is similar to the PVC glue strip.

3. thermoplastic elastomer TPE sealing strip

TPE elastomer seal is a new material development from abroad based technology and domestic independent research and development in recent years. It is mainly used for the seal of the car doors and windows, in recent years began to seal for building doors and windows. Its outstanding advantage is that:

The service life can be comparable to that of vulcanized three yuan EPDM sealing strip.

The processing energy consumption is lower than that of vulcanized three yuan ethylene propylene rubber strip

No heavy metals such as lead and halogen can be recovered after a few years. It meets the requirements of green building materials.
