    Features & Benefits

    Benefits

    Using LSR materials have the following molding benefits:

    • LSR molding cycle time is measured in seconds, as opposed to minutes by other methods.
    • LSR molding materials are pre-mixed in a closed system, preventing contamination.
    • Using LSR in the LIM process produces less scrap from excess rubber molding material than other methods.
    • The flow properties of liquid silicone rubber make it ideal for molding smaller, tight tolerance parts.
    • The flow properties of LSR also make it essential to manufacture a precision tool to prevent secondary operations caused by excess flash in the molding process.
    • LSR is a cured rubber silicone with low compression set, great stability and the ability to resist extreme temperature variations.
    • LSR components range from medical device valves to gas diaphragms.
