Liquid silicone rubber (LSR) elastomer offers numerous advantages with a wide variety of grades available: general purpose, food-grade, medical, self-adhesive, low-volatile, optically clear, and specialty grades in a range of durometers from very firm to very soft. LSR materials provide superior heat and flame resistance, making them ideal for electrical, automotive, and industrial applications. Their natural biocompatibility and hypo-allergenic properties make them perfect for skin-contact products.

LSR maintains its original shape after numerous compressions, even in extreme temperatures, distinguishing it from other elastomer polymers. While naturally translucent white, LSR can be pigmented in various colors.

Nearly every industry has discovered the benefits of LSR and liquid injection molding for products including:

• Seals, gaskets, and thin membranes
• Insulators and cushions
• Valves and bladders
• Respiratory masks
• Syringes and IV components
• Wearable health monitoring devices
• Electronic components
• Food and beverage products

Silicone rubber applications in the automotive industry are growing rapidly due to their resistance to fuel and lubricant erosion. They improve component performance and reduce maintenance costs. Applications include ignition wires, spark plug protective covers, radiator hoses, muffler linings, battery connectors, and fuel pump components. Room temperature curing silicone is widely used for electronic part sealing, windshield glass, and body sealing.

Silicone rubber is essential for insulating materials in electronics, used in TV anode covers, high voltage protection, refrigerator defroster wires, and power transmission cables. It replaces ceramic insulators in transmission lines, especially ultra-high voltage applications. Conductive silicone is used in electronic contacts, while flame-retardant varieties are critical in nuclear power stations. Heating elements made from silicone control temperatures in instruments and medical devices.

As a high-performance material, silicone rubber withstands extreme space temperatures, extending aircraft component life and reducing maintenance. Applications include aircraft body seals, electrical connectors, engine O-rings, oxygen masks, and radar shock absorbers. Flame-resistant silicone protects rocket components from jet exhaust damage.

Silicone's weather resistance makes it ideal for construction sealants, used in precast concrete, curtain walls, and bathroom tile joints. High-temperature cured silicone sponge strips serve as door and window seals, with potential to replace asphalt in highway joints as prices decrease.
