Sealing strips come in spring

Doors and windows of development history, too, is the history of the sealing strip. Replacement of windows and doors, also led to the replacement of the sealing strip. However, Chinese-style production concept but well worth considering - blindly cut costs, low-cost competition. Door and window accessories sector, many big brands, Kennedy Lang, Young, Noto, Sijiliya ...... but seal the big brands very much. Let's not technical problems, the problem is the production of ideas. Hope seal industry boss who insist do yourself, do not be down with the low price of small manufacturers, doors and windows to China tomorrow, the more his own, doing a responsible seal. Door and window accessories sector truly do the big brands.self-locking cable ties
First, natural rubber sealing strip era
The mid-1990s with the ordinary steel doors and windows aluminum windows and doors as well as ordinary wooden windows, doors and windows China has accounted for almost all of the share. Natural rubber sealing strip is then the era of China's small workshop-style production model, Chinese-style lower costs, coupled with the lack of natural rubber itself, resistant to aging in the natural environment, a few months cracking, hardening, fracture, and finally in the steel doors and windows are prohibited by the state to use at the same time, the market will gradually fade out ...... two, PVC PVC sealing strip
The last century in the late 1990s, steel doors windows are synonymous with nobility. There was a story, Hebei Province, a provincial officials personally to a steel profile factory line a half months to get profiles. Ushered in the era of plastic windows and doors, and the state began to promote the sealing strip on the use of PVC sealing strip, PVC seal its not crack, easy to weld, became the darling of steel doors and windows sealed. However, only 2-3 years, the question arises. PVC plasticizers precipitation, this troubled world industry problems, in PVC seal has been significantly reflected. As plasticizer precipitation, resulting in a strip contamination profiles, length contraction, off-sectional contraction, Mifengbuyan problems abound. The Chinese-style small workshop processing, Chinese-style lower costs, Chinese-style low-price competition, leading to a poor quality recycled PVC plasticizers and applications, is exacerbated by the problem of the entire seal industry, and thus the end of PVC sealing strip starting to show.tamper evident labels
