Sörbo produced the first ever silicone extruded squeegee blade. It is softer than natural rubber. It is also self-lubricating so it’s always silky smooth on glass. It does not change or lose memory in extremely cold climates. It is resilient in temperatures below0°F (-18°C)and resists harsh conditions, so it essentially stays fresh indefinitely. Inventory is reduced because the silicone can simply be cut to any length you need when you need it. Also, it’s easier to track since it comes in 50 foot lengths. With our Docket squeegee rubber sharpener, this silicone blade cuts like butter and is nice and straight every time. Companion to Sörbo Eliminator line (link to https://youtube/71N2-1RhutY).

Sörbo invented the Silicone Blade in 1998.Instructions for use: For best results, wipe off the silicone blade at the start of each workday.
