Silicone elastomers are gaining popularity as a high performing material for use in piping and molds. Here’s a quick overview of some of the major pros and cons associated with the industrial use of silicone elastomers.
Liquid silicone rubber (LSR) molds and tubing are becoming increasingly popular in manufacturing and a number of other industrial processes. Silicone molds and tubing are distinguished by the type of curing process they employ. Peroxide-cured silicone uses a process called free radical curing, whereas platinum-cured silicone uses addition curing.
The possibilities with rubber, plastic and silicone molding unfold like an infinite universe, so it can be overwhelming to navigate the industry and all of its offerings as you search for exactly the right “thing.” It might be anything from a rubber o-ring or weather stripping to a tiny computer part or element used in aerospace, but it is usually needed to accomplish a business goal or to complete some sort of mission or project.
Silicone rubber is used to manufacture a number of different items, including irrigation and filtration components, seals and gaskets, lighted buttons, overmolded parts, and more. It is prized for its high thermal stability, durable mechanical properties, UV resistance and other characteristics. If you’re considering using silicone for your next custom rubber molding project, there are a few things to consider when choosing a vendor.
Silicone rubber is a thermoset with a backbone of alternating silicone and oxygen atoms with methyl or vinyl side groups. There are two types of silicone rubber: solid and liquid. The basic structure of the two types of silicone rubber is the same, but curing and processing are radically different.
