Wiper Substrates & Edge Treatment

When you are buying new wipers there is a lot to consider. Similar to gloves you have to consider the 5 C's: cost, capacity, cleanliness, chemical compatibility, and construction. On-top of the 5 C's you also have to worry about the edge treatment that you choose to use in your critical environment. There are a lot of different options for you to choose from:

Pressure Heat-Sealed: This is used for synthetic wipers and is accomplished by forming a flat edge on the wiper that eliminates any stray threads from being exposed. This is the cleanest of all edge treatments. 

Ultrasonic-Sealed: This is superior to laser sealed because it delivers a softer edge with a lower carbon level. An ultrasonic sealed edge is thinner than the substrate. 

Laser Sealed: This allows for particulate retention because the laser uses heat to seal the edge of the wiper. This is superior in cost and precision. 

Wire Cut: This uses a hot wire similar to the way a poll bag is heat-sealed. The border is not as clean as a laser cut or heat sealed edge, but it much lower in cost. 

Cold Knife Cut: This uses a steal blade to cut the fabric. This method can leave a lot of fibers on the wiper and can lead to contamination when used.
