Since Charles Goodyear discovered the sulfur curing of NR in 1839, many studies have been carried out to understand its mechanism. Nowadays, the broadly accepted mechanism includes an activated accelerator Zn-complex which enables sulfur coupling to the polymer in the allylic position to the double bond. Modern passenger car tire treads no longer contain natural rubber but a blend of SSBR and BR, filled with a silica /silane system. Is it possible to transfer all NR-gained knowledge to such a modern passenger car tire tread formulation or is re-thinking sulfur curing required?

What the audience will learn

• Re-thinking sulfur curing for SSBR-based compounds
• That long-known knowledge should not be taken for granted when something in the system has changed
• That the use of ZnO and stearic acid is not required for an effective curing of SSBR
• That sulfer can undergo a radical crosslinking mechanism
• That sometimes less is more

The first part of the paper 'Re-thinking sulfur curing' shows that sulfur curing in a high-vinyl SSBR compound follows a different mechanism than in NR. A direct radical coupling – preferably to vinyl – takes place. In the second part, the impact of the presence of carbon black, silica/silane and DPG on the mechanism of sulfur curing in SSBR is further investigated. Based on these findings, future tire tread compounds don’t require the addition of activators and DPG. This enables the production of cheaper greener tires which release much less harmful substances in the environment.

The potential of FAC is appraised against that of process oil (presence of toxic PCA materials) as well as silane coupling agents to assess its potency as a multifunctional additive (MFA). The replacement of 66% of SCA and 100% of oil with FAC has shown comparable physico-mechanical, dynamic-mechanical flow behavior with reference to the reference one. A plausible mechanism is also offered to substantiate this. Thus, this FAC can be applied to develop a cost-effective sustainable tread formulation.

At the tire’s point of view for carbon emissions, the effect of the use stage is very significant. When a tire's rolling resistance is reduced, carbon emissions may be reduced by improving energy efficiency in this stage. In this study, an extreme level of low rolling resistance was developed by applying new materials in the tire. The impact of tread compounds and reinforcement components (belt, carcass) was studied through vehicle evaluation. However, the LRR tire had performance trade-offs such as R&H, so further efforts were made to improve it. In conclusion, the carbon reduction effect of the LRR tire was confirmed.

The new regulatory requirements on wet grip of worn tires aim to ensure that tire performance is assessed at their end of life, i.e. when worn, ensuring tires meet requirements throughout their life and are not replaced prematurely. Wet braking, a critical performance affecting road safety, dramatically deteriorates in worn tires. For practical reasons, the current regulation sets criteria on buffed tires (new tires with artificially reduced tread depth); however, naturally worn tires may perform differently due to several other factors. This joint study between JRC and UNINA investigates performance discrepancies.

What the audience will learn

• Wet braking performance requirements
• Regulatory developments
• Factors affecting braking on wet surfaces
• Buffed tires versus naturally worn tires

Regulation and supply chain requirements increasingly push sustainability criteria to be fulfilled. This may include circular economy claims such as renewable or recycled content, but also CO2 emissions of upstream supply chains (Scope 3). However, gaps exist in the field of correctly assessing upstream supply chains in order to correctly develop a claim to be associated with the end product. Various methodologies are described in standards, which can be a foundation for calculating claims for the tire material fractions. However, harmonization is lacking. Single manufacturers of tire components are taking the lead in developing their own rules, but acceptance in the overall tire composition is questionable. A further discussion point is the acceptance of mass balancing and the sub-methods in order to simplify chain-of-custody consideration. TÜV Süd gives some insight into the discussion on how green claims about tires can be correctly stated and what developments in standardization and regulation are currently underway.

Global ecological trends are requiring that tires and rubber become more sustainable. This reflects not only the transition from mineral-based to bio-based components but also extends share of renewable-based components used in tires and rubber. Some monitoring of this trend shows that is it not revolutionary but a gradual evolutionary transition. The reasons for this are the lack of an industry standard for some important renewable components, as well as tire makers' need to keep tire properties at the same or better level. Should tire makers move quicker in this transition or carefully continue, step by step ?

When driving a vehicle, not only does tire abrasion occur, generating very large amounts of small rubber particles, but there is also an enormous production of gases, known as chemical emission, that are released into the environment. These gases are generated mainly when the tire heats up during rolling, but they are maximally emitted into the air during the total collapse of the tire, known as blow-up. In this study, we will introduce an experimental laboratory method of the heat build-up process (HBU) from room temperature to blow-up, with visualization of the generation and emission of gases into the air.

When exposed to air, the long polymer chains of a rubbery object react with the oxygen molecules to form oxygenated functional groups which weaken the material and make it more susceptible to cracking. Higher temperature accelerates the diffusion of oxygen and the mechanisms of the ensuing chemical reactions. The property degradation of the oxidative rubber is manifested by embrittlement of its stiffness, reduction of its maximum chain extensibility and accelerated crack initiation and propagation. In this paper, a process is developed to measure the oxygen permeability, solubility and oxygen consumption rate to map the state of oxygen concentration.

The most common road surface characterization metric used in friction models is power spectral density (PSD). However, PSDs tell us little about how roughness is distributed locally on the surface and may misinterpret the frequency signature of edge falloffs as high-frequency roughness. A new method for surface-scan processing is presented, which uses the frequency content, as well as the height and gradient distributions of the roughness. This method results in the generation of realistic virtual surfaces which, combined with a novel approach for friction estimation, highlight the importance of accurate road representation.
