The Versatility of Liquid Silicone Rubber

Liquid silicone rubber (LSR) is a two-part, platinum-cured elastomer that manufacturers inject into mold cavities to create components that withstand weather extremes and product aging. This versatile product remains useful in temperatures as low as -65°C and as high as 150°C.

Lasting Benefits for Any Application and Industry

Several additional characteristics render LSR the material of choice for many different applications and industries. Some key examples include:

  • Biocompatibility: LSR’s elastomeric composition enables it to resist bacterial growth. It’s entirely tasteless and odorless, and tests have indicated exceptional compatibility with human body fluids and tissue
  • Chemical resistance: LSR can resist oxidation and corrosive chemicals
  • Temperature resistance: LSR can withstand low and high temperature extremes
  • Mechanical properties: LSR offers high tear resistance and tensile strength along with excellent flexibility and elongation capacities
  • Electric properties: LSR can insulate against many different forms of electricity
  • Transparency and pigmentation: Because LSR is naturally transparent, it allows manufacturers to create colorful and fully customized rubber-molded products

Consumer Goods and Electronics

Consumers today seek high-quality, durable goods built to last. Working LSR into your manufacturing processes can make the difference between products people buy and products they leave on the shelf. LSR silicone appears in a diverse field of everyday items such as:

  • Kitchen goods: Baking pans, spatulas, barbecue brushes, and cooking pans
  • Cosmetic goods: Mascara brushes, makeup applicators, and lipstick molds
  • Wearable technology: Fitness trackers and smartwatches
  • Electronics: Small components like connector seals, grommets, and strain-relief devices

Automotive Industry

LSR is seeing an exponential rise in use among vehicle manufacturers. Because it can withstand extreme weather conditions and stretching, it’s an excellent material to use in a variety of automotive applications, including:

  • Windshield wipers, which incorporate LSR due to its heat resistance and flexibility
  • LED headlights, which use LSR’s transparency to amplify emitted light, resulting in better visual clarity for drivers; because LED bulbs use less energy than other light bulbs, LSR enables cars to be more energy efficient and budget friendly
  • Airbag coating and sealing
  • Components used under the hoods of vehicles
  • Buttons, gaskets, and wiring harness components

Healthcare and Medical Devices

LSR helps manufacturers create safe and reliable medical devices and components. Medical devices need to operate within tight tolerances to improve the safety and health of patients and providers. LSR helps meet these specifications while keeping parts cost efficient:

  • Medical devices placed inside patients’ bodies are commonly made of LSR, because this material won’t leak potentially dangerous chemicals
  • Drug-eluding devices (DEDs)
  • Flow-control valves and syringe stoppers
  • Baby care products
  • Implants
  • Wearable devices for monitoring
  • Respiratory masks
