EMI Silicone Rubber & Liquid Silicone Rubber – Engineered for Demanding Environments

Some materials have to do more than just hold their shape. In electronics, defense, and high-precision manufacturing, the compounds you choose need to perform under pressure — quite literally. That's where EMI silicone rubber earns its place.

At Polystar Technologies, we've been working with silicone and liquid silicone rubber compounds since 1997. Over the years, we've developed more than 250 active formulations — many of them built for highly specialized applications where standard materials simply won't cut it.

Liquid Silicone Rubber – Versatility at Its Best

Liquid silicone rubber (LSR) takes things a step further. Because it's injection-moulded rather than compression-moulded, it can fill intricate geometries and tight tolerances that would be difficult or impossible to achieve with conventional rubber processing.

LSR is widely used in consumer electronics, automotive sensors, medical-grade seals, and anywhere that clean, consistent, high-volume production is needed. It cures quickly, maintains its properties across a wide temperature range, and is inherently resistant to moisture, UV, and many chemicals — making it one of the more dependable materials in precision rubber manufacturing.
