The volume off PLC produced is far lower than the volumes of RSS and TSR.
PLC are lighter in colour than their RSS and TSR counterparts.
The properties demanded of PLCs are:
The main consumer industries are:
The end uses are:
PLCs method of manufacture ensures the following:
As the term implies, Sole Crepe is a special form of latex crepe used in shoe soles. Sole crepe is the only finished product made by a plantation and commands a higher value than normal PLC in view of its very precise manufacture and it being regarded as a finished product as opposed to an intermediate product. It could be produced in smooth or pebbly finishes, and in thicknesses varying from 3, 6, 8 and 12 mm.
Sole Crepe could also be made in a variety of different colours by the addition of suitable dyes. It finds application in fashion shoes, casual shoes and fancy shoes. To that extent it is a fashion item for which demand could vary from season to season.
On a more practical level, Sole Crepe provides the best grip on ice of any known synthetic or natural rubber. It prevents static electric shock generated as a result of abrasion of shoes soles on rough surfaces. It also finds application in winter boots and industrial boots for use inside cold rooms, by virtue of providing the best grip on ice
