Basically a rubber band consists of an extruded natural rubber tube which is cured or vulcanised and cut to the size required by the customer.
The diameter and thickness and colour of the tube is determined according to the customer’s requirements. The rubber tube is cured on aluminium mandrels of a fixed diameter, the availability of these mandrels determines the diameters that can be produced.
The choice of the quality and dimensions determines the strength, stiffness and stretch properties of the finished product. This determines how easy it is to use the product. |
