Most generally offered Wiper Blades are made from natural rubber, and in order to control manufacturing costs, the actual rubber blades have varying ratios of carbon black and other fillers. Every day the Wiper Blades are exposed to elements and conditions which accelerate the breakdown of these fillers and the rubber encasing them. This accelerates the blade becoming stiff and cracking & tearing. Along with actual usage, sunlight, pollution, ozone, and extreme temperatures are the most common causes of car wiper blade breakdown.

The best Silicone Wiper Blades are made from very pure silicone resin. This elastomer is much sought after for its temperature stability, resistance to chemical, pollution, ozone and Ultra Violet degradation, water repellence, and long service life. Silicone resin is used in lots of aerospace, pharmaceutical, medical,and automotive applications due to its hugely superior qualities when compared to natural rubber. The key base raw material in Silicone Wiper Blades – silicone – is also the key base raw material of windscreen glass. This ensures maximum compatibility and conformity between car wiper blade and windscreen.

In theory, starting with a better base theoretically ensures a better car wiper blade, but that can only be true if everything else matches to the quality of the best silicone elastomers, from conception, through design, other material choices, manufacturing quality & tolerances to packaging and distribution.

It’s highly vital to keep in mind that the actual wiping is done with just a hairline edge that runs along either side of the tip of the car wiper blade. For maximum performance, the edge must completely conform to the contours of the windscreen. Only a very Pure Silicone Resin car wiper blade in a high quality frame can guarantee this conformity. Additionally, because these Wiper Blades are made from very pure silicone, they leave behind a microscopic coating of silicone oils on the windscreen.

This means that after an hour or so’s use, the driver will see the build up of a Rain Repellent effect, just like that obtained from those rather costly proprietary windscreen treatments which ensure water repellence & beading. When a high quality silicone car wiper blade is combined with a high quality frame which allows longitudinal flexibility whilst maintaining very good lateral rigidity & accurate positioning, the whole system reduces the risk of car wiper blade chattering and cuts down the friction which can lead to a burnt out wiper motor, blown fuses or thermal cut outs, or mechanical failure in the wiper transmission system.

Therefore, if you want to have the best safety and performance particularly in extreme weather go for Silicone Wiper Blades. If you want the ultimate in looks, performance, safety and life go for Silicone Flatblade Wipers. To make sure that you’re buying high quality Silicone Wiper Blades, look for those with a guarantee, and beware of those makers who don’t offer one.
