Most commonly available Car Wiper Blades are manufactured from natural rubber, and in order to minimise manufacturing costs, the actual rubber blades have different mixtures of carbon black and other fillers. Each day the Car Wiper Blades are exposed to elements and conditions which add to the degradation of these fillers and the rubber encasing them. This accelerates the blade becoming brittle and cracking & tearing. Along with actual usage, sunlight, pollution, ozone, and extreme temperatures are the most common causes of wiper blade degradation.
The best Silicone Windscreen Wiper Blades are manufactured with extremely 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 vastly superior qualities when compared with natural rubber. The chief base raw material in Silicone Screen Wipers - silicone - is also the chief base raw material of windscreen glass. This ensures maximum compatibility and conformity between wiper blade and windscreen.
In theory, starting with a better base theoretically produces a better wiper blade, However this can only be true if everything else comes up to the quality of the best silicone elastomers, from conception, through design, other material choices, manufacturing quality & tolerances to packaging and distribution.
It is really imperative to bear in mind that the actual wiping is done by just a microscopic edge that runs along either side of the tip of the wiper blade. For maximum effectiveness, this edge must faithfully conform to the curve of the windscreen. Only an extremely Pure Silicone Resin wiper blade in a high quality frame can guarantee this conformity. In addition, because these Car Wiper Blades are made from very pure silicone, they deposit a microscopic coating of silicone oils on the windscreen.
This ensures that over an hour or so’s use, the motorist will see the build up of a Rain Repellent effect, just like that obtained from those somewhat expensive proprietary windscreen treatments which promote water repellence & beading. When a high quality silicone wiper blade is mounted in a high quality frame which permits longitudinal flexibility whilst maintaining very good lateral rigidity & accurate positioning, the whole system reduces the risk of wiper blade chattering and minimises 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 especially in extreme conditions pick Silicone Windscreen Wiper Blades. If you want the ultimate in looks, performance, safety and life pick Silicone Flatblade Wipers. To make sure that you’re getting high quality Silicone Windscreen Wiper Blades, look for those with a guarantee, and beware of those makers who don’t offer one.
