Reclaimed Rubber
Rubber reclaim, more usually called Reclaimed rubber, or just Recycled rubber refers to waste or scrap vulcanised (cured) that has been rendered fit for re-use by a complicated thermo-chemical process.
The waste rubber is granulated quite small to release and facilitate the removal of any metal and fabric that may be contained.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 reclaimed rubber.
Antai is a larger reclaimed rubber manufacturer in China,and can provide offers in a variety of Reclaim Rubber grades for use as tyre and non-tyre rubber products. Reclaimed rubber is an extremely effective and environmentally friendly source of rubber manufactured (without compromising on quality and versatility) from the end of life and/or factory waste of whole tyres, tread peelings, natural rubber tubes, butyl tubes. It is manufactured using the de-polymerisation process, which results in reclaimed rubber a product that can be used as a partial substitute for natural and synthetic rubber.
