Sörbo produced the first ever extruded silicone squeegee blade. It is softer than natural rubber. It is also self-lubricating so it is always silky smooth on glass. It does not change and does not lose its memory in extremely cold climates. It is resilient at temperatures below -18°C (0°F) and withstands harsh conditions, so it stays essentially fresh indefinitely. Supplies are reduced because the silicone can easily be cut to the desired length when you need it. It is also easier to keep track of as it comes in 15.24m lengths. With our Docket rubber sharpener, this silicone blade cuts like butter and is nice and straight every time. Perfectly suited to the Sörbo Eliminator line. Sörbo invented the Silicone Blade in 1998. Instructions for use: Wipe the silicone blade at the beginning of each working day for best results.
