Abstract
A polymer film is provided, wherein the polymer film is composed of polyol, isocyanate and chain extender. The content ratio in weight of the polyol, the isocyanate and the chain extender is (80.00 to 100.00):(70.00 to 90.00):(10.00 to 20.00). The average functionality of the polyol is greater than or equal to 2, and the average functionality of the chain extender is greater than 2. As such, it has better structural strength and good shock-absorbing and buffering capabilities in various dimensions.
