Is the PE protective film scratch-resistant and scratch-resistant?
Aug 16, 2022
Whether the PE protective film is scratch-resistant and scratch-resistant is a problem that everyone is currently concerned about. At present, the scratch-resistant materials on the market are basically the same (2-3H), and the performance is also good, only scratch-resistant and non-scratch-resistant. The test method is to use a pencil with a hardness of 3H, press and push it away on the PE protective film for 10 times at a 45-degree angle of 500G, and if there is no scratch, it is considered that the hardness of 3H can be reached.
There is also a simple method, which is to use a slightly harder metal device or a newly cut nail to scratch on the PE protective film with the strength of a normal stylus. Make sure it is scratch resistant.
