ATT have a number of compounds available to flatproof different tyre sizes and applications. 

These range from 8.5 x 2 electric scooter tyres up to 235/85R16 light utility vehicles.

 Each compound consists of two different components (Part 1 and Part 2) that are mixed together before injection into tyres. 

Once inside the tyre, the material expands (foams) to fill the whole air space, and gels (sets) to form a resilient, rubbery foam core. At the end of the process there is no air remaining in the tyre.

There are two types of equipment available to apply Aerofill - Single Shot, and Low-Pressure PU Dispenser. 

Single Shot:•	For small runs and larger tyres•	Inexpensive •	Easy to set up and use

PU Dispenser:•	High throughput and efficiency•	Cleaning only at the end of a batch of tyres, not after each one

ATT provides full training and ongoing support to our tyre flatproofing customers. The cost to flatproof a tyre with Aerofil is similar to that of traditional fill. However, the benefits include much lighter wheel mass and a smoother, more compliant ride.

The table below compares the weight of Aerofill with traditional fill (e.g. Tyrfil) required to flatproof some of the tyres we process.
