PU-coated sealing strip is the most common sealing product in our life. It has long service life, rich and gorgeous color, wear resistance, high temperature resistance, corrosion resistance and aging resistance, and can play a long-term sealing effect. According to statistics, sealing strip is the most widely used in doors and windows. It is very popular because of its own characteristics of wind, dust, noise reduction, heat preservation and so on. Today Henry takes you to know about the pu-coated sealing strip.

1. What is PU-coated seal strip?

I-ECO cladding seal strip is composed of high resilience PU (polyurethane) foam, PE (polyethylene) film, PP (polypropylene) and TPE support skeleton.

2. What are the characteristics of PU-coated sealing strip?

Collision-proof, sound-proof, insect-proof, wind-proof, light-proof and smoke-proof

3. What are the main types of PU-coated seals?

There are two main types: self-adhesive type and chuck type.

Self-adhesive type: double-sided tape, sandwich for grid glass fiber

Chuck type: PP skeleton and TPU fish-bone barb with perfect combination of plastic and rubber

4. How long can the PU-coated sealing strip last?

Stable performance and long service life are maintained in different environments, anti-aging, wear resistance, service life of up to 20 years.

5. Superior performance of PU-coated sealing strip:

Compression Deformation Test: 50% compression rate at 70 C lasts 22 hours, and the deformation rate is less than 10%.

Compression test, under 25% compression rate, applied 15N/100mm pressure, compression rate < 10N

Temperature Range Testing: There is no obvious change in sealing performance from - 40 ~90.

Heat conduction K value test: K value < 0.035W/m2K at 0 ~C;

Fatigue test: imitate the window switch 500,000 times, no obvious change in shape

Sound insulation test: 43 dB noise reduction with only intermediate tape windows

Windows with intermediate tape and additional tape reduce noise by 45 decibels

Outdoor Aging Resistance Testing: It has been over 20 years, and its performance is in good condition.

6. Is it necessary to maintain PU-coated seals?

Unwanted! Surface wrapped polyethylene material, easy to clean the surface, no maintenance!

7. What is the effect of PU-coated sealing strip after installation?

Windbreak: After sealing, candle inspection, flame does not flutter. 100% seal

Dust-proof: After sealing, no dust can be seen on the windowsill to avoid dust attack. clean

Noise reduction: Users in downtown areas and along highways, noise reduction 50% - 70%, quiet

Insulation: In winter, the indoor temperature before and after sealing differs by 3-6 degrees. Keep indoors cool in summer

Power saving: Users with air conditioning can save 15% - 20% of their electricity per month.

Save money: Sealed doors and windows cost one-tenth of the cost of redo doors and windows
