Types Of Caps
Plastic caps and plastic plugs are made from different materials to suit your needs. The main materials that Harman Corporation uses are silicone, rubber and vinyl. Let’s break down their different properties.
Silicone caps, with their soft flexibility and high heat tolerance (up to 600 degrees fahrenheit), are perfect high-temperature masks that are used in painting, powder coating, anodizing, E-coating, and electroplating
EPDM Rubber Caps
Like silicone caps, rubber caps are resistant to high-heat (up to 350 F / 177 C), making them useful in anodizing and painting. Rubber caps provide a very tight seal and the are also flexible, like silicone caps. Rubber caps are especially great as noise inhibitors.
While vinyl caps do not offer the same resistance to high temperature as silicone and rubber caps, they provide an airtight seal for added insulation and cushion.
