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.

A seat for an indoor bicycle made with Hemcell bio-based polylactic acid (PLA) mixed with palm leaf waste. This innovative material is home compostable as a result of the unique process Hemcell use. The PLA is partially degraded during processing, which opens up the polymer structure. This produces a material with some performance enhancements, like higher stiffness and heat deflection temperature (HDT), but also the possibility to be home compostable at relatively thick wall sections. Once exposed to heat, humidity, sunlight and microorganisms, the material starts to breakdown naturally.

Renault interior door panel made with LYB LyondelBasell polypropylene (PP) with a chemical foaming agent added to produce a foamed part. This approach helps to save 15-20% weight. The texture is designed to eliminate the need for a covering, to save cost and ensure the part can be recycled end of life.

Renault A pillar interior trim made with LYB LyondelBasell polypropylene copolymer (PPC). A special effect compound is added to create the speckled appearance in combination with moulded textile texture, eliminating the need for covering.
