The Rob Allen 16mm Green Rubber for spearguns is manufactured by Dip processing. While costing more, this enables fewer additives to be used, enhancing performance on a gun. The coloured outer layer increases protection from the environment, and the amber inner core is purer for performance.
This rubber has been trialled and tested to provide up to 40% greater strength than other manufacturers.

Some Interesting facts about Rubber:
It takes several quite distinct steps to make a product out of natural rubber. First, you have to gather your latex from the rubber trees using a traditional process called rubber tapping. That involves making a wide, V-shaped cut in the tree’s bark. As the latex drips out, it’s collected in a cup.
The latex from many trees is then filtered, washed, and reacted with acid. This makes the particles of rubber coagulate (stick together). The rubber made this way is pressed into slabs or sheets and then dried..
By itself, unprocessed rubber is not all that useful. It tends to be brittle when cold and smelly and sticky when it warms up. Further processes are used to turn it into a much more versatile material.
- Masticating machines “chew up” raw rubber using mechanical rollers and presses. This makes the rubber softer, easier to work, and more sticky.
- After the rubber has been masticated, extra chemical ingredients are mixed in to improve its properties (for example, to make it more hard wearing).
- Next, the rubber is squashed into shape by rollers (a process called calendaring) or squeezed through specially shaped holes to make hollow tubes (a process known as extrusion).
- Finally, the rubber is vulcanised (cooked): sulphur is added and the rubber is heated to about 140°C (280°F).
