FAQS
Here you can see the most frequently asked questions.
Are your products sustainable soles?
Tiresoul supplies the strips obtained directly from the tire that we are giving a second life to, what would technically be called the ROLLING BAND; it is the outer layer of rubber that surrounds the tire and makes contact with the asphalt. Once removed, it is a strip of rubber of approximately 180cm. The measurements are not homogeneous, since, depending on the size and model of the original tire, these measurements vary.
Is the tire width always the same?
We have two width variants: the narrow - which are bands between 11 and 14cm - and the wide - which are bands between 14 and 18cm. Depending on the needs of your footwear, you can purchase one variant or the other.
How are the bands delivered?
We can ship your order in boxes for small orders or on pallets if you want to place a large order. Check with our team for the best shipping offer or ask for pick-up at our facilities with your trusted delivery company.
How many soles can I produce from one tread?
3 to 4 pairs can be produced, depending on the size of the shoe last.
What is the thickness of the tread?
At Tiresoul we can adjust the thickness of the tread to the thickness you need for both textile and non-textile treads. What we do ask for is a minimum of 4mm for quality standards.
What is the tread textile?
It is a layer of the tire that is not visible, as it is underneath the rubber. They are nylon or aramid threads that reinforce the structure of the tire. This layer reduces the elasticity of the tread to 20%, although it reinforces it structurally. We can remove this textile to make the material more flexible and thus easier to work with for the footwear industry.
Is there a difference between "with" or "without" textile?
The material WITH TEXTILE is more rigid and consistent. The material WITHOUT TEXTILE is much more flexible. Also the adhesive you use can have different effects on the band depending on whether you buy it with or without textile.
Are all models available?
Our stock is directly linked to the automotive world, so depending on the natural consumption of different tires we will have more or less stock of our products. However, before placing any order we will inform you if there is any problem in the supply of certain models.
What is the composition of the material?
The base composition of the mixture is SBR, and it is specifically additivated to resist UV radiation and ozone, as well as to have excellent grip and wear resistance properties in any type of environmental condition, since it is designed to maintain its properties intact in environments of extreme cold, heat, humidity, salinity, etc.
What footwear manufacturing processes are compatible with this material?
Tread rubber is fully compatible with other rubber products for the footwear industry. To date, we have customers using gluing, stitching, stapling, vulcanizing, shear vulcanizing and autoclaving processes.
Is any special treatment necessary in the gluing process?
Tire soles do not require any special processes compared to other rubber soles. We would use the same advice; sanding the surface of the rubber and/or applying liquid alogen on it makes the bonding stronger. Liquid allogen is the impregnation used for rubber. Each material has a certain recommended impregnation whose application strengthens the bond.
Can it be sewn in the same way as leather?
Yes, although the maximum recommended thickness for sewing is 6mm. The lesser the thickness, the easier this process will be.
Is our material compatible with the manufacture of soles and/or footwear through vulcanization?
Yes, it is compatible with the vulcanizing process and with the cut vulcanizing process. For the vulcanizing process, due to the high pressures reached during the process, it is recommended to use low thicknesses to avoid deformations. For the shear vulcanizing process, as lower pressures are used, higher thicknesses can be used.
Is our material compatible with the manufacture of footwear through the autoclave process?
Yes
Is our material compatible with the manufacture of soles or footwear through injection?
To date, it has not been possible to make the tread compatible with polyurethane injection. For injection of other materials, it is recommended to carry out prior tests to verify if they are compatible. Our technical team can propose processes prior to the introduction of the part in the mold to activate the bonding surface.
What advantages does Tiresoul have over other materials?
The main advantage is to take advantage of the excellent properties of the tire, resistance, grip and abrasion. In addition, it is a sustainable material, 100% recycled through a mechanical process, without thermal or chemical processes or tire shredding. Environmentally friendly. We extend the useful life of the tire through an innovative recycling initiative, proposing this material as another alternative for the footwear industry.
