How are these materials packaged?

Our rubbers, plastics, foams and other materials come to you packaged in plastic or metal containers of various sizes and configurations. What determines the "pack out" configuration of a rubber, plastic of foam system is 1) the mix ratio of the system (A + B); 2) the viscosity of the material; and 3) the density of the material.

Unit Sizes (A+B) Include:

  • Trial Units – come to you packaged in pint bottles, quart bottles, pint jars or quart jars.
  • Gallon Units – packaged in gallon plastic buckets, metal cans or glass bottles.
  • 5 Gallon Units – packaged in 5 gallon plastic and metal buckets.
  • 55 Gallon Units – packaged in metal or plastic drums.
  • Tote Units – equal 5 drum units. Packaged in a foil bag inside a heavy duty cardboard box.

How much material comes in a unit?

Materials are packed by weight, and each unit has a published net weight representing the actual amount of material (A+B) comes with the unit. Don't estimate the amount of material needed for your application by volume. Smooth-On offers an easy to use “material calculator” that lets you estimate the amount of material you will need for your project. Click here to go to the material calculator.

Why are some containers only half full of material?

Our rubbers, plastics and foams are dispensed into the above containers by weight. Depending on the density of the material that you buy or the mix ratio of the system, the volume of the material in theses containers may be less or more. Related FAQ: Was I shorted material?
