Differences between pale crepe and sole crepe
Both of pale crepe (sometimes called as crepe) and sole crepe are manufactured in a similar way. In manufacturing crepe rubber number of passes through the mill is a important thing.
1. Sole crepe is send more passes through mills. Therefore thickness of sole crepe is less than pale crepe.
Example: 13 passes for sole crepe and 7 passes for pale crepe.
2. Sole crepe is more cleaner than pale crepe because sole crepe is used to manufacture pharmaceuticals items.
3. Sole crepe is more white than pale crepe. Sole crepe is washed more during manufacturing. Therefore its non rubber materials (proteins....) are removed. These proteins may cause to discolouration of crepe rubber.
