1. Τι είναι η λωρίδα σφράγισης με PU;

The wrapped sealing strip is composed of high rebound PU (polyurethane) foam material, outer PE (polyethylene) film, and PP (polypropylene) and TPE support skeleton inside;

2. What are the characteristics of PU encapsulated sealing strips?

Collision proof, sound insulation, insect proof, wind proof, light proof, smoke proof, and waterproof

3. Ποιοι είναι οι κύριοι τύποι λωρίδων σφράγισης με ενθυλακωμένες PU;

Υπάρχουν κυρίως δύο τύποι: ο αυτοκόλλητος τύπος και ο τύπος υποδοχής κάρτας

Self adhesive type: double-sided adhesive tape with grid glass fiber interlayer

Card slot type: PP skeleton and TPU fishbone barb hook with perfect combination of plastic and rubber

4. How long can PU encapsulated sealing strips last?

Σταθερή απόδοση και μεγάλη διάρκεια ζωής σε διαφορετικά περιβάλλοντα, αντιγήρανση και αντοχή στη φθορά, διάρκεια ζωής έως 20 χρόνια.

5. PU encapsulated sealing strip with superior performance:

Compression deformation test: 50% compression rate at 70 ℃ for 22 hours, deformation rate ≤ 10%

Compression force test, apply a force of 15N/100mm at a compression rate of 25%, with a compression rate of ≤ 10N

Temperature range test: No significant change in sealing performance from -40 ℃ to 90 ℃

Heat conduction K value test: K value ≤ 0.035W/m2K at 0 ℃;

Fatigue resistance test: Simulate window opening and closing 500000 times without significant changes in shape

Sound insulation test: with only the middle rubber strip window, noise reduction of 43 decibels

Windows with intermediate and additional adhesive strips reduce noise by 45 decibels

Outdoor aging resistance test: Currently over 20 years old, with intact performance

6. Do you need to maintain PU encapsulated sealing strip products?

No need! The surface is wrapped in polyethylene material, making it easy to clean and maintenance free!

7. What is the effect of installing PU encapsulated sealing strips?

Wind proof: After sealing, check with candles to ensure that the flames do not flutter. 100% sealing

Dust prevention: After sealing, dust can no longer be seen on the windowsill, preventing it from being attacked by sand and dust. clean

Noise reduction: For users in busy urban areas and on highways, noise reduction is 50% -70%, quiet

Insulation: The difference in indoor temperature before and after sealing in winter is 3-6 degrees. Keep indoor cool in summer

Energy saving: Users with air conditioning can save 15% -20% of their monthly electricity.
