Advantages and characteristics of EPDM sealing strip

Advantages of EPDM sealing strip:

1. The performance and service life of the sealing strip are equivalent to that of EPDM vulcanized sealing strip.

2. The processing energy consumption is lower than that of EPDM vulcanizate (equivalent to PVC).

3. It does not contain heavy metals such as halogen and lead, and can be recycled after several years, meeting the requirements of green building materials.

4. Small proportion (only 0.9-0.95) and high window rate. It seems that the purchase unit price is high and the actual use cost is low. In recent years, this kind of product has developed rapidly in the use of building doors and windows.

Product characteristics of EPDM sealing strip:

1. Light volume weight, large expansion strength, no water absorption (instead of traditional three oil four felt, asphalt wood fir board and other materials). Product environmental protection, simple construction, anti-seepage, leak proof, water stop effect is good.

2. Corrosion resistance, aging resistance, high and low temperature resistance + 80 ℃ ~ - 45 ℃ without flowing, deformation, embrittlement and long service life.

3. It has an independent open hole bubble structure, and the special joint plate has the appearance of honeycomb holes evenly distributed. It can be tightly bonded with cement / sealant without roughening, adapt to the change of natural expansion and contraction, and enhance the sealing expansion and water sealing effect of the joint.

In fact, in the actual production process of doors and windows, the investment of sealing strip accounts for a small proportion, but its role can not be ignored. Such as water-proof, sealing and energy-saving, sound insulation, dust-proof, antifreeze, heat preservation, temperature resistance, aging resistance, these functions can not be ignored in daily life.
