No, tyres contain over 40 different types of rubber in them, as well as metal and textile. We focus on Tyre Tread Buffings from truck tyres only, which are made of a single specific compound of rubber, hence it’s purity and any metal content is removed with powerful magnets.
These are the tread of the tyres of trucks only that have been ‘buffed’ off the tyre to create a smooth finish on the tyre carcass. This process is like grating cheese, using angled blades to remove the tread material from the tyre without damaging the tyre, ready to have a new tread cured onto, or stuck onto the remaining carcass.
The buffings need to relatively clean, small amounts of metal from the buffing process is acceptable, as it will be collected by our magnets, but other debris, such as leaves or dirt are more difficult to remove and could contaminate the final products.
We are an ISO:9001 accredited company, so we use batch numbers to track the origin and sale of our tyre tread products. We also test our products daily to ensure our product is within our product specification and we are audited once a year to keep our accreditation and quality processes up to date. We only purchase from sources that have been approved and have been shown to be trustworthy for a long time.
Rubber shred and rubber crumb are generic terms to describe the size of the pieces of rubber that pass through a sieving process. Larger pieces of rubber are sieved off first and are called shred, these include ‘oversize’ and 2/3’s. The smaller pieces of rubber are sieved out last and are more powder-like, so are called Crumb, our standard sizes include 12’s, 30’s and 40’, but sizes can be made to suit the customer’s need.
The sizings for both the rubber crumb and shred refer to the size of mesh used in the sieves that allow a set size of particle through. For example, a 30’s mesh sieve has a pore size that allows rubber particles of that size and smaller through. For more information, you can download our technical and safety data sheets from our products page.
We manufacture multiple sizings of tyre tread crumb and shred in the same process, thus each grade has a range of sizes, with the majority being the size of the sieve’s mesh. We have set specifications for each grade, allowing for set percentages of sizes of rubber in each grade, which are checked daily for each batch of production, recorded and a sample kept for future reference. We also use powerful magnets at multiple stages of production to ensure our material is free of metals. We have over 50 years of history in producing quality products.

As all of our material is tyre tread buffings, the resultant sieved material is pure and extremely useful in a whole range of areas, from artificial turf, mulch, carpet underlay, playground base layer, gardening shred, adhesives, moulded products to being mixed into virgin rubber compound to be remoulded into new tyre tread.
We are happy to send a sample of our material for you to trial, please phone us or use the ‘contact us’ page to send an email and we will arrange a sample for you to see our material for yourself.
Give us a call! Or send an email via the Contact page, even if the rubber you have is not tyre tread buffings, our sister company J Allcock and Sons may be interested in it.
