Note on j-sen clip available

Thank you for using our clip.
Our clip We will be using a polycarbonate resin.
Polycarbonate has good transparency, strength also has a strong advantage, but please note that there is a risk of damage at the following situation.

1.The use of the thing a thick

Our clip it becomes basically utilizing the principle of leverage structure.
It takes a considerable amount of weight on the combination part of the parts at the time of opening and closing.
Possible that sandwich the thing with the thickness of up to a certain extent, if that is continue to use in the same situation, there is a risk of shape change, please note that there is a risk in the worst case, lead to corruption.
If it is available to those with a thick, we recommend more a small clip from the shape of large (5,6,21L type) clip of shape.
If you can tell in advance for your intended use, we will propose a more suitable product.

2.chemical resistance

Polycarbonate resin is there is not good disadvantage in regard to chemical durability.
In particular alkaline agent, tend to deteriorate in a solvent, epoxy adhesives has been unsuitable.
Please refer to because I was allowed to specify the chemical resistance in Exhibit.
However, since you do not mean to say that all is certainly true if you have any questions, please contact us.

3.hazardous substances

Polycarbonate that you are using in our clip, we have cleared both the reference value "bisphenol A", "formaldehyde".
Please tell us if you go in so we will offer a copy of both the test results.
