Foam Expo offers you direct contact with the engineers and executives who produce materials and products used in automotive, aerospace, construction, medical, packaging, and sports and leisure. You’ll see exhibitions of materials and products that set new standards across a wide range of applications. Our aim is to give the technical foams industry the stage it truly deserves. If you are involved in the purchasing, integration, manufacture or supply of materials, products or equipment, you can be certain that your suppliers, customers, competitors and peers will all be at the show!

The Joy of Rubber & Plastics

Written by John M. Bonforte, Sr.,
Monmouth Rubber & Plastics Corp.

The ‘Joy of Rubber & Plastics‘ is our 34-page educational booklet, containing definitions, practical advice and explanations concerning closed cell materials.


This book was written for all of us who grew up in a time when closed cell sponge rubber was a taboo subject. One which we dare not ask either our parents or grandparents to explain, let alone a sales manager. If you are like most people from our generation, you had to learn about closed cell sponge on the streets or in dark alleys. Even after we progressed into our respective business careers little, if any, information was available as to the basic facts of how closed cell sponge is made and used. This book is an attempt to bring this verboten subject out of the closet and perhaps maybe some day even into the classroom.

Chapter One will be a definition of terms. Before going into a brief description of what closed cell sponge is and how it is made, it is important that certain basic terms used in the industry are defined. Keep in mind when reading these definitions that they have often been misused and that you are probably accustomed to hearing them used in the wrong way. While your proper understanding of these terms is necessary, the most important point is that your technical communication with the factory be correct.


The ‘JOY OF RUBBER & PLASTICS’ is Free to read and download.

    What would you like to Ask John about today?
  • Jenna speaks “Hi John. Customers have been asking about the shelf life of rubber. They say everything they have read is way too complicated. Can you explain it in easy to understand terms?”
    Can you explain it in easy to understand terms?”
  • Shelf life is a rather broad term that can mean different things to different companies and/or people.
    We keep our customer out of trouble
    with proper technical informationThat is why we have
    “ASK JOHN”
  • There are published tables that list the recommended shelf life for various polymers. These tables are only a guide for the following reasons:
  • There are published tables that list the recommended shelf life for various polymers. These tables are only a guide for the following reasons:
  • The environmental conditions under which the specific compound is stored affects shelf life.
  • Some of these conditions are: temperature, humidity, source of light if any, oxygen and ozone exposure, deformation, contact with foreign materials during storage such as liquids, semi-solid materials, metal, and non-metal materials
  • NOTE: that shelf life relates only to the functional use of the compound over a period of time when properly stored. It does not relate to how the material may or may not perform in any specific application.
  • Keeping what we just learned in mind it is important not to confuse Shelf Life with Service Life
  • Shelf Life relates to storage only. It is separate and distinct from Service Life.
  • Storage conditions as detailed previously will affect not only the Shelf Life but also the Service Life of a specific rubber formulation.
  • Shelf Life relates to storage only. It is separate and distinct from Service Life.
  • Storage conditions as detailed previously will affect not only the Shelf Life but also the Service Life of a specific rubber formulation.
  • When properly stored, that is not exposed to the negative storage variables, the Shelf Life of Monmouth’s products are minimum of at least one year.
  • The Durafoam™ DK series, specifically DK1111, DK2121, DK3131, DK4141, and DK5151 have been stored at room temperature, out of direct light, for 15+ years with no visible degradation.
  • Physical property testing for density, compression deflection and color change show no statistically significant change as it relates to these 15 year old retains.
  • If you need further information and clarification as it relates to Shelf Life contact us with all the test parameters required so that we can give a more specific answer to your shelf life concerns.
