These include the ability to mold
parts with deep draws and varying thickness within the part, which
creates the opportunity to mold in logos, foot-tread ribbing, undercuts,
lips, and additional sound adsorption in specific areas. "Wavy-wavy" paper has better energy-adsorbing
properties; therefore it can stand energy adsorption without breaking. In the new method, a controlled solvent environment is created
around the thin film so that an equilibrium amount of adsorption occurs. |
