The invention relates to the field of polymer materials and processing. Provided are a polymer sheet and a manufacturing method and a use thereof. The polymer sheet has a thickness less than its average hole diameter. The polymer sheet is in the form of a cellular board having through holes in the thickness direction, and has a through-hole ratio of 20%-60%, a thickness of 10-500 μm, and an average hole diameter of 10-500 μm. The manufacturing method comprises a roll material supplying step, a continuous cutting step and a rolling step. The continuous cutting step has a precision error of ±0.02 mm. The above method can be used to manufacture a material having a low density, high impact resistance, a high compression rate, and low compression set and capable of serving as a sealing and buffering material for an electronic device. |
