Cross-section through a Goodyear tyre revealing the metal structure inside the composite rubber matrix. The two main synthetic rubbers in car tyres are polybutadiene rubber (BR) and styrene butadiene rubber (SBR). They are typically used in combination with around 20% natural rubber (NR). Tyres used in more demanding applications, such as trucks and aircraft, contain a higher proportion of natural rubber. A whole host of other materials and additives are used, including steel cable, reinforcing textile and fillers (predominately carbon black and silica for conductivity and enhanced resistance to tearing and abrasion) to give the desired performance.

Wastea vegan leather made with bio-based polyurethane resin (bio-PUR) and waste tea leaves. A durable and resilient material, it is suitable for applications in fashion, apparel, interiors, furniture, upholstery and automotive.

Modern Synthesis are developing nanocellulose-based biomaterials, such as leather-like fabrics. Bacteria grow the raw material, nanocellulose, as a natural byproduct of fermentation. Modern Synthesis then creates a customised nanocellulose biofilm, which they combine with a natural textile to create a versatile range of non-woven materials.

A demonstrator by Kurz to show off their wood-effect polyester foil hot stamped onto acrylic sheet, which is backlit with integrated tough sensor. A black mask is printed on the reverse side of the semi-transparent foil, which helps control the lighting effect. This kind of technology is used in appliances as well as automotive applications. In car interior applications, where head impact is a risk, polycarbonate (PC) is preferred over acrylic (PMMA).
