Won't they break?


EPDM Rubber Rings (Ethylene Propylene Diene Monomer)
EPDM is typically used in the roofing industry. It is latex free, UV resistant and FDA approved.


EPDM O Rings have a strength Durometer rating of 70.
Compare that next to a standard rubber band used in offices (which is thicker and far stronger than a loom band) which has a Durometer rating of 20 and you can see why these are the perfect choice for stretchy jewellery; and are most definitely not flimsy little elastic circles like Loom Bands!
The colours are nice and even throughout each ring, and closely match available Anodised Aluminium rings making them perfect for bright coloured combination jewellery.
It must be noted however, that colours can vary slightly from batch to batch, however this just makes every chain woven entirely unique!
Note: A durometer scale is a type of measurement for rubber material hardness. The rubber durometer chart below gives you an idea of the rubber hardness
20 = Rubber Band
40 = Pencil Eraser
60 = Car Tire Tread
70 = Running Shoe Sole
80 = Leather Belt
100 = Shopping Cart Wheel

Why use EPDM O Rings to make jewellery?

EPDM is an excellent choice for stretchy jewellery.  Woven with Stainless Steel rings you can be assured of a nice solid weight and a bracelet that will not come apart or stretch out of shape. 
The downside:
  • EPDM however does not play well with Chlorine - never wear them while swimming in a chlorinated pool!
  • EPDM does not play well with oils either.  Take it easy on the sun oils and perfumes when wearing EPDM.
Benfits of using EPDM over other rubbers:
  • They are latex free (great for those with Latex allergies.  Human allergy reactions to EPDM are rare but not unheard of)
  • UV resistant (colour stays truer for longer)
  • High durability (long life with little to no maintenance required)
  • They are EXTREMELY difficult to break
  • And of course, they look AWESOME!
