Technical Details & Test Data
- How is Reclaim Produced?
The waste rubber is granulated quite small to release and facilitate the removal of any metal and fabric that may be present.It is then subject to a combination of heat, pressure and chemical softening /plasticising agents for a period of time in a large retort.After discharge, the treated waste is refined to remove any nibs or hard bits of unprocessed material. This is done by extruder sieving and/or a refining mill.The material passes repeatedly through the mill and the coarse "bits" are pushed out to the sides of the mill nip (the wider part, due to the camber) and fall out into catchment trays at each side. The good, refined material is taken off the mill as a paper thin sheet and wound up on itself to make thick slab. The material from the sides can be used to make lower grade, coarser "tailings" reclaim.
Packaging & Availability
- Packaging Type
- Packaging
Each blanket weighs approximately 5 kilos. Whole and cut blankets are made up to 25 kilos nett, and this amount is then packed in polyethylene bags on pallets, and shrink- wrapped. 40 such parcels are packed onto a strong pallet, so giving a unit load of 1,000-kilos net weight. The pallets have overall dimensions of 1,120mm x 1,120mm x 1,120mm and should not be double stacked. Alternative methods of packaging are also available.
Storage & Handling
- Storage
Recommended conditions are dry storage in a cool atmosphere. There will be a slow increase of Mooney viscosity on storage, for which a maximum of one year is recommended.
