Technical Data

E-Leather has been tested extensively to determine the ultimate performance of the material. This confirms a factor of safety as high as 5 times above the specifications for some products.

Designed and developed to overcome the weaknesses of traditional leather and textiles, E-Leather is engineered to provide a range of materials that meet specific performance criteria.
