The main component of silicone rubber bands is organic silicon polymer (usually polydimethylsiloxane, PDMS), and the rubber band is made of natural rubber (NR), mainly extracted from latex of Hevea brasiliensis, with polyisoprene as the main component.
Silicone rubber band
advantage:
Temperature resistance: silica gel is resistant to high and low temperatures (-60 ℃~250 ℃), suitable for extreme environments (such as high temperature disinfection, freezing) Chemical stability: anti-aging, ozone resistant, UV resistant, not easy to become sticky or crack due to light or oxidation.
Color stability: Not easy to fade, maintaining a bright color for a long time.
Disadvantages:
Poor elasticity: Resilience and elongation are usually lower than rubber, and long-term stretching can lead to permanent deformation.
High cost: The price is 2-5 times that of rubber bands.
Low friction: The surface is smooth and may slide easily (such as poor fixation when tying hair).
Rubber bands
advantage:
High elasticity: Natural rubber has a tensile strength of up to 500% to 800%, good resilience, and is suitable for scenarios that require strong and sturdy fixation.
Low cost: The raw materials are cheap and suitable for large-scale use (such as office and agriculture).
Strong grip strength: high surface friction, more secure fixation (such as tying items).
Disadvantages:
Easy to age: prone to sticking and cracking under UV, ozone, and high temperatures (with a typical lifespan of 1-3 years).
Not solvent resistant: Contact with oil or chemical solvents may cause swelling and damage.
Potential allergies: Natural rubber contains protein, which may cause skin allergies.

Rubber bands are more environmentally friendly, and natural rubber is biodegradable
Natural rubber comes from plants and can be gradually decomposed by microorganisms in natural environments (taking months to years), making it more easily degradable than plastic or silicone.
Whether it's silicone rubber bands or rubber bands, what suits you is the best.
