Material Information

Download Material Properties Chart

StockCap uses a variety of materials in the production of plugs, caps and all our other products. A special section of our website groups materials into three categories designed to assist you in making the selection process of a cap or plug quick and easy. Vinyl may be the most economical, but rubber products can often be reused for longer periods. Plastic caps and plugs are typically firm, not flexible like vinyl. All materials are generally weather resistant. For deeper comparison, review our material properties chart by clicking here or the button on the side.

Some materials are not compatible with the various applications of our products. For example, our high temperature vinyl products can be a money saving factor for masking in paint applications, but would not withstand the even higher temperatures that silicone products can endure. For general guidance, click the link below for a selection guide.

It is the responsibility of the purchaser [of our products] to determine the use of our product(s) as safe, lawful and technically suitable in their intended applications.

Our vinyl products do not meet the Food and Drug Administration requirement of 21 CFR 177 for contact with food.

Most of the materials used in the manufacturing of StockCap products can be recycled, however, it is necessary to check with your local recycling center for a list of accepted materials.
