- Strength properties (tear, tensile, etc.) as indicated on the data sheets, are given on a per mil basis. For example, if both a 20.0 ga. and a 30.0 ga. sheet has a tear strength of 170 gms/mil, the total strength of the 20.0 ga. sheet will be 170x20=3400 gms, but the total strength of the 30.0 ga. sheet will be 170x30=5100 gms. Therefore, in general, the thicker the sheet, the greater will be the overall strength properties.
- Puncture resistance will be greater.
- The rate of plasticizer loss or stiffening will be slower. This will become a factor only after may years in service.
- Slightly better dimensional stability (i.e. lower shrinkage) as indicated by lab test results.
