- Uses
The basic EPDM material is very inert and is very resistant to the effects of oxygen, ozone and aging. Therefore the resulting crumb can be added to virgin compounds without any deleterious effects.
- How to Use
Use in the same way as you would use any other crumb.
Properties
Technical Details & Test Data
- How are Rubber Granules Produced?
The incoming waste is identified and checked and is then progressively broken down in size by passing it through very high energy cutters and granulators. The granulators have a removable, perforated "basket" as the base and this can be changed as required. The full range of sizes runs from 2.5 to 30mm. The common, usual sizes would be 4 or 6mm, and larger chunks would "whirl" around inside, passing through the cutters again and again, until they were small enough to fall through the basket. Vibrating sieve units separate or grade the output. High strength magnets are used at every possible flow point to ensure that any residual metal particles are removed.
At this stage the material is known as "granules" and has a ready outlet in safety surfacing and the like. It is used in the same way as the stone "chips" in tarmac.
