For over 50 years, our rubber bands established their reputation in such diverse areas as agriculture, industry, stationery, packaging …

Our latest innovations on the product has led us to diversify into new areas such as: Fashion, Design and Screen Printing.

Rubber Band Basics

How To Measure A Rubber Band
Rubber bands are measured via three dimensions – Length (lay flat length), Width (cut width), and Thickness. — [ check our Rubber Band Size Chart ]

flatlength 1. Pinch a rubber bands at each end as if to lay the band flat. The distance from end to end is the band length.
cutwidth 2. The width of the band measures how wide the band is, perpendicular to the length.
wallthickness 3. The thickness measures the wall of the band. Thickness generally ranges from 1.1 mm – 2.5 mm.


Common Rubber Band Terminology

Common filler in rubber band compounds. There is no such thing as a 100% pure rubber band. All compounds require the addition of other materials to create a finished product.
The formula for a particular rubber band compound. With over 80 years of experience and product development, Jakmousse has designed specific compounds with varying stretch performance to create application specific bands (soft stretch vs. tight stretch).
The process by which a compound reaches its final intended state through heat, chemical reaction, evaporation, etc.
Bands that require a “custom” production run. Includes variations in wall thickness and or flat length and non-standard colors.
With the band laying flat, this would be measured across the band perpendicular to the flat length.
Measure of the hardness of non-metallic materials or “resistance to indentation.”
Generic term for various elastic substances resembling rubber
extension or “stretch” of a rubber band
(ETHYLENE PROPYLENE DIENE MONOMER) Synthetic rubber compound which provides superior properties for outdoor and all-weather temperature applications because of its excellent resistance to ozone, oxidants and severe weather conditions.
The process of creating rubber tubing in a defined shape by forcing uncured material through a die.
Pinch the two ends of the band together and lay on a flat surface. The measurement from end to end equals the flat length. (If you were to cut one end of the band and unfold it, the flat length would be approximately half the overall length)
Many plants produce latex, which oozes from cuts and injuries as a milky sap. Rubber is a coagulated, elastic latex containing long-chain hydrocarbons.
Containing no latex proteins. Jakmousse offers a custom line of bands produced from synthetic polyisoprene (synthetic rubber) for applications with potential allergic reactions to latex proteins.
The ability of a rubber band to return to its original shape after being stretched.
Ratio of stress to strain. Also expressed as the tensile strength at a given percentage of elongation.
Variation in standard cut width or packaging versus standard bands.
After a rubber band has been stretched, it will typically come to rest at a longer length than before it was stretched. This increase in length is commonly referred to as “permanent set” and is expressed as a percent of the original length of the band.
The extent to which a rubber band does not return to its original shape after being stretched.
the ratio of the density (weight) of a substance to the density of water.
Jakmousse currently offers several hundred of the most common sizes of rubber bands. These are produced in four distinct lines (with varying stretch performance and count per pound) and a variety of colors. Deviations from standard items are classified as either non-standard or “custom”.
resistance of a material to stretch. Typically expressed as pounds per inch at the breaking point of a particular rubber band.
the allowable deviation from a standard; the range of variation permitted in maintaining a specified dimension.
Elongation at point of failure.
The curing process of rubber which cross-links the molecules into a strong chain, giving the rubber its stretch and strength. This is achieved through the application of heat combined with the appropriate chemicals.
Refers to the thickness of the wall of the extruded rubber tube.
The number of rubber bands per gram.

Rubber bands are made by extruding the rubber into a long tube to provide its general shape, putting the tubes on mandrels, curing the rubber with heat, and then slicing it across the width of the tube into little bands. This causes the tube to split into multiple sections, creating a rubber band.


We Make Evironmentally Friendly Rubber Products




The rising tide of environmental consciousness has put rubber cultivation in favorable light. Atmospheric pollution from the release of ‘greenhouse gases’, especially carbon dioxide, from the combustion of fossil fuels and the depletion of forests, especially the tropical rain forests, have been viewed with great concern.

Studies have shown that rubber trees convert carbon dioxide at a rate comparable to if not better than that of the natural forest. The potential of natural rubber for sequestering the carbon from the atmosphere to support the ecosystem is widely recognized and adopted for establishing new forests or for reforestation purposes.

Besides being environmentally friendly, most of our rubber bands are made from latex, a rapidly renewable resource.
