“100% SBR” on fabric usually means the material or backing is made entirely from styrene-butadiene rubber , a synthetic rubber/latex-like polymer used for coating or reinforcing textiles. It is commonly used to reduce fraying, improve grip, and add durability, while changing the fabric’s drape only a little.

What it means

  • SBR stands for styrene-butadiene rubber, a synthetic rubber made from styrene and butadiene.
  • On fabric labels, “100% SBR” usually refers to the coating, backing, or laminated layer , not necessarily the face fabric itself.
  • It is often used in industrial, upholstery, or technical fabrics rather than everyday clothing.

What to expect

  • More resistance to fraying and slipping.
  • Slightly stronger fabric overall.
  • A synthetic rubber feel, sometimes with less breathability than uncoated cloth.
  • It is not the same as natural latex, and it is generally described as different from natural latex allergy concerns.

Simple example

If a fabric listing says “polyester with 100% SBR backing,” the polyester is the main cloth, and the SBR is the rubber backing added for stability and durability.

Why it matters

If you are choosing fabric for sewing, upholstery, or gear, 100% SBR usually signals a more technical material that may be tougher to cut or more rigid than plain fabric. If you want, I can also explain whether it is suitable for clothing, upholstery, or wetsuit-style material.
