Whether you’re a product designer, manufacturer, or hobbyist, at some point you might come across a piece of webbing and wonder exactly what material it is. Identifying your webbing, whether it's nylon, polyester, or polypropylene, is crucial for making sure it meets your application's needs, such as strength, UV resistance, and water tolerance.

Luckily, you don't need special equipment or a lab to identify webbing. Here are three quick, easy, and cost-free tests you can perform at home to identify your webbing material.

The float test quickly distinguishes polypropylene webbing from nylon and polyester by checking its buoyancy.

How to Perform the Float Test:

• Fill a clear container or bucket with room-temperature water.
  
  

• Drop a small piece of webbing into the water.
  
  

• Observe the behavior of the webbing sample.
  
  

Results:

• Polypropylene: Floats (it’s lighter than water).
  
  

• Nylon: Sinks (it’s heavier than water).
  
  

• Polyester: Sinks (it’s also heavier than water).
  
  

The burn test provides clear visual clues to help distinguish among nylon, polyester, and polypropylene webbing based on their burning behavior.

Safety Tip:
 Perform this test outdoors or in a well-ventilated area. Use tweezers or pliers to hold the sample, and always keep water nearby.

How to Perform the Burn Test:

• Hold a small piece of webbing using tweezers.
  
  

• Light the edge of the webbing with a match or lighter.
  
  

• Observe the flame color, smoke appearance, and melting behavior.
  
  

Results:

• Nylon: Melts and burns slowly, producing white smoke and a blue flame with a yellowish tip. It drips while burning and leaves a hard, gray or tan bead.
  
  

• Polyester: Burns and melts simultaneously with blackish smoke, producing a sweet, chemical smell. It leaves behind a hard, dark-colored bead.
  
  

The odor test helps further confirm your identification by the smell the material emits while burning or smoldering.

How to Perform the Odor Test:

• After completing the burn test, extinguish the flame.
  
  

• Gently waft the smoke toward your nose (avoid direct inhalation).
  
  

Results:

• Nylon: Produces a distinct odor resembling celery or fish.
  
  

• Polyester: Emits a somewhat sweet chemical odor, like burnt sealing wax or faintly sweet oil.
  
  

• Polypropylene: Gives off an odor reminiscent of burning asphalt, candle wax, or paraffin.
