What are the raw materials of the door and window seals How to choose the door and window seals

Doors and windows are not well sealed, not only will lead to more indoor dust, but also produce noise, therefore, when found in the home noise, can look at the window whether the installation of sealing strips, or sealing strips with or without shedding, if there is no sealing strips, it is necessary to buy a little bit in the purchase of the former, the PChouse to give you a list of some of the more common raw materials and methods of selection, and I hope to be useful to you.

First, what are the raw materials of the door and window sealing strip

1, TPV seal

TPV raw material elasticity is okay, after professional planning and research and development, quality assurance, the use of appropriate good, and with the progress and development of production technology, raw materials, there are more new enhancements, so that it can be more suitable for home life in the use of the needs of the present, and easily bring outstanding benefits.

2, EPDM sealing tape

EPDM is a copolymer of ethylene, propylene and a few non-conjugated diolefins, is a kind of ethylene propylene rubber. EPDM sealing tape has ozone resistance, weather resistance, high and low temperature resistance, chemical resistance, resistance to a variety of polar solutes, relative density is small. The disadvantage is that in general mineral oil and lubricating oil in the expansion of large, generally dark-colored products. Application temperature range -60～+150℃. It can be applied to high temperature, cold, coastal, ultraviolet ray illumination intense area and the middle and high level construction.

3、PVC sealing strip

The main ingredient is polyvinyl chloride, in addition to adding plasticizers and other ingredients to enhance its heat resistance, resistance, ductility, etc. PVC sealing strip is easy to mold, recyclable, reusable.

Second, how to choose door and window seals

1, appearance

Selection of door and window sealing strip should pay attention to whether the sealing strip has significant cracks, whether it shows unevenness and so on. In the selection of sealing strips can be scraped with fingernails to see whether the appearance is simple to be scraped white, because this door and window sealing strips installed, just hard objects bumping or minor scratches, will lead to fine sealing strips "broken like", very unattractive.

2, elasticity

In the selection of the seal can pull the seal, pull the seal by hand, look at the elasticity of the seal, high quality seal good elasticity, after stretching can rebound to the original length.

3, brightness

Some of the cheaper sealing strip filler will be a lot of filler put together, so the appearance will not be very bright, those cheap and not bright aluminum alloy doors and windows sealing strip is not.

There are many kinds of sealing material, the above is the more common three, in the selection of sealing, can first understand what its raw materials, in addition to the appearance, elasticity and other aspects of the selection.
