Advantages:
| 1. Easy to construction |
| 2. Low release force, easy peel off when remove the release film |
| 3. High residual adhesiveness rate(≥80%) to prevent the influence of silicon transfer on products(We also can do UV curing type, adhesiveness rate can be done more than 90%) |
| 4. Environmental Production technology of solvent and solvent-free products |
| 5. Environmentally Friendly. Can be recycling |
| 6. High temperature resistance than PE, can resistance 130-160 degrees |
Application:
Release Film for Butyl Tapes
