Silicone rubber compounds have excellent electrical properties, great resistance to heat and cold, and remarkable chemical stability and flame retardant qualities. These types of benefits make them sought after for use in nearly every industry. You’ll frequently see them used in:

• automobiles,
• food-related production,
• electric and electronic equipment,
• office automation equipment,
• leisure products,
• household good and much more.

Silicone rubbers have properties of both inorganic and organic materials. They are composed of unique silicone gums and high-purity silica. Thus, silicone rubbers offer many outstanding features not found in other organic rubbers.

Let’s take a closer look at a few more their impressive features:

Heat and Cold Resistance

At 150°C there is almost no change in physical properties, and they maintain elasticity at temperatures at which typical organic rubbers become brittle.

Weather Resistance

Silicone rubbers can be exposed to UV rays, wind, and rain for long periods with almost no change in physical properties.

Oil Resistance, Solvent Resistance, Chemical Resistance

Silicone rubbers have superior oil resistance at high temperatures. They also have outstanding resistance to solvents and other chemicals, and are nearly impervious to polar organic compounds and dilute acids and alkalis.

Electrically Insulative

They are stable over a wide range of temperatures and frequencies. And even when immersed in water, there is almost no decline in performance.

Here are a few of the top-quality silicone rubber compounds carried by Chemical Concepts:

Chem-Set™ QM140 Silicone Rubber with Catalyst 

QM 140 has excellent mechanical properties and good shelf-life stability. This material is an excellent choice for molding intricate patterns, skin molding and applications where high durometer, dimensional stability and extremely tough rubber are required.

A Few Key Features

• High tear strength.
• Low viscosity.
• Fast demold time.
• Excellent dimensional stability.

Devcon® Silite® RTV Silicone (clear)

This single-component sealant is often used for sealing panels, window plates, bonding and sealing appliance ports, attaching brackets, nameplates, ceramic tile, and bonding gaskets.

A Few Key Features

• Excellent resistance to a wide range of weather and temperatures ranging from –60° to 450°F.
• Cures at room temperature to a flexible silicone rubber.
• Ready to use for gasketing, sealing, bonding, and weatherproofing applications.
• Acceptable for use in meat and poultry plants.

A few of the intended uses for Devcon Silite include weather-proofing electrical components, caulking plumbing fixtures, sealing glass, and making form-in-place gaskets.

QM 260 

QM 260 is a two-component, room temperature, addition cure silicone material. The cured rubber has excellent mechanical properties and good shelf-life stability. This material is a good choice for the molding of furniture, picture frames and architectural materials. QM 260 is exceptionally good where high durometer and dimensional stability are required.

A Few Key Features

• Casting resin resistance
• Fast demold time
• Excellent dimensional stability
• High durometer

QM 260 offers many applications. Here are just a few suggestions:

• Molds for architectural replication.
• Molds for polyester, epoxy resin casting, and rigid or foam polyurethane.
• Molds for technical articles and prototypes.
• Molds for furniture and picture frame replication.
• Candy and other food molds.
