The sealing strip of doors and windows is one of the important factors affecting the quality of doors and windows. It needs to have important functions of waterproofing, sealing, and energy saving. It has the functions of sound insulation, dustproof, antifreeze, and warmth. It also has strong tensile strength and good elasticity. , It needs better temperature resistance and aging resistance. In this mixed market environment, how to identify good quality?
1. Combustion method (it can distinguish between hot rubber body and rubber strip)
A. Rubber-like strips become ash after burning, and cannot be drawn. Among them, the ash is white, and the extinguished part is still white after rubbing on white paper is silicone rubber; the ash is black, and the extinguished part is black after rubbing on white paper is EPDM or neoprene rubber; The ash is black, and the sticky touch at the place where it goes out is natural rubber.
B. After burning, the thermoplastic elastic rubber strip can be drawn into filaments at the extinguishing point, and EVA (ethylene-vinyl acetate copolymer) has a clear acetic acid smell. PE (polyethylene) and PP (polypropylene) have obvious candle-burning taste, which can be burned continuously and accompanied by low melting. PVC (Polyvinyl Chloride) rubber strips have the characteristics of being extinguished when they are separated from the fire and are accompanied by black smoke and pungent odors.
C.TPV thermoplastic vulcanizate: The surface is matt, with melting and drawing phenomenon, floating on the water surface or suspended in water.
D.SEBS Thermoplastic Elastomer Sealing Strip: The surface is matt, there is a phenomenon of melting and drawing, and it sinks slowly in water.

2. Tensile measurement
Relatively speaking, as a sealing tape material, it should have a certain tensile strength, the standard requirement: strength ≥ 5Mpa. The higher the glue content of the same material, the better the tensile force. Generally speaking, the service life will be relatively longer and the sealing effect will be better.
3. Smell the smell
Use your nose to smell for any peculiar smell. Normal PVC material has a bit of mellow smell, almost no peculiar smell.
4. High temperature detection
Wrap the sealing strip on the profile as tightly as possible and leave it at high temperature for a period of time (on the roof or in a sunny place). Check whether the contact surface between the profile surface and the sealing strip is stained or discolored, whether the dust on the surface of the sealing strip is yellow (the oil is easy to absorb the soil), and whether the hands are dirty.
5. Observe the color
There are a lot of fillers for some cheaper sealing strips, so the surface will not be very shiny. Those who are cheap and not shiny are not advisable.
The sealing performance of doors and windows mainly depends on the sealing strip. The performance and life of the sealing strip product mainly lies in the choice of material. Therefore, it is recommended to buy high-quality door and window sealing tape when buying!

This is the fitting blog for anybody who needs to find out about this topic. You realize so much its almost laborious to argue with you (not that I actually would want…HaHa). You definitely put a brand new spin on a subject thats been written about for years. Nice stuff, just great!
Sorry for the later reply, thanks for your comment. Give me more motivation to move forward!
