The WAHI manufacture and supply many different silicone rubber products. We have the technical capabilities to provide a broad scope of bespoke silicone engineered solutions including: extrusions, mouldings, gaskets, inflatable seals, sheeting, hoses and bellows.

Silicone rubber is an incredible compound with outstanding performance in lots of different areas. This makes it a very versatile material and the reason we use silicone rubber for products in almost every industry.

Silicone is a synthetic rubber produced from the chemical element silicon, with properties that organic rubbers just cannot match.

Silicone Rubber Key Features

• Extreme temperature resistance (from -70°C to +300°C)
• Excellent resilience to weathering and environmental influence 
• FDA approved compounds
• Good electrical insulation properties
• Mechanical damping properties 
• Good rebound and recovery 
• Fire retardant to EN45545-2 grades
• Repels water providing tight sealing solutions
• Metal detectable range
• Can be produced in various colours

We are constantly working with compounders and in the laboratory to formulate new silicone rubbers and exceed performance expectations. All of silicones fantastic features are why so many of our partners use it in their industry.

What is silicone & rubber molds?

Liquid silicone & rubber mold is a thermoset process that mixes a two-component compound together, which is then heat cured in the mold with a platinum catalyst to produce a final LSR part.

Why Choose Liquid Silicon & Rubber Mold for your project?

Liquid Silicon Rubber has excellent thermal, electrical, and chemical resistance properties, although it can be attacked by certain solvents such as gasoline or mineral spirits, which is why it can be used in high-temperature automotive applications but not for fuel lines.

And it has low compression set—low permanent deformation when a force is applied and removed—making it ideal for elastomers. This allows for faster and most cost-effective tooling when compared to traditional steel molds.

We offer a number of additional molding and tooling services to support your project

Basic guidelines for liquid silicone rubber molding include important design considerations to help improve part mold-ability, enhance cosmetic appearance, and reduce overall production time.
