The Importance of Protection and Insulation against High Temperatures

Our headquarters are based in Florida, so it's no surprise that we're experts in protecting things against the heat.

What's The Big Deal about Insulation?

Put simply, for some environments, cables just can't withstand the harshness on their own. For example, if you are driving your car, boat, or flying a plane you are constantly relying on a LOT of different wires and cables to get you from point A to point B safely. These kinds of crafts often reach high temperatures and it's important to do as much as possible to keep your engine safe.

Aside from heat, we have sleeves that can keep cables safe from damage, chemicals and water.
