Your wiper blade will remove any dust, dirt, debris and grime that can accumulate over time on your car windscreen, it provides you a safe driving condition.

A good wiping performace is directly based on your wiper blade rubber refill. Here are two types of rubber refill coating: Teflon coating and Graphite coating. What is the difference?

Teflon was discovered in 1938, the products coated is heatproof and non-stick. Teflon is a synthetic polymer, which is containing carbon and fluorine, so it also called Polytetrafluoroethylene.

Teflon coating is made by placing the rubber refill in liquid, with more even absorption and longer adhesion time. The Teflon coated rubber refill contains a small amount of graphite, but not exsit same problem with total graphite coating.

Graphite coating is made by placing the rubber refill in the roller and rolling it for about 6 hours to allow the graphite to adhere to the surface of the rubber strip for lubrication. It may roll unevenly and the adhesion time is very short (it is easy to get black paint on the touch).

From the service life, the residence time of graphite coating is about 1-2 months, and Teflon can stay for more than half a year.

As above, Teflon coating rubber is better than graphite, which provides added flexibililty to changes in the winter elements for improved visibility.

What other advantages of Teflon coating:

1. Low friction – it has the lowest coefficient of friction within all solids, nothing sticks on it.

2. A very broad temperature range – the melting point of approximately +327°C which makes it virtually unbreakable in extreme temperatures.

3. Flexible and bendable – even at low temperatures, easy to use on a diversity of surfaces without it being deprived of its durability.
