Notwithstanding the increasing demand for polymeric materials in an extraordinary variety of applications, the engineers have often only limited tools suitable for the design of parts made of polymers, both in terms of mathematical models and reliable material data, which together constitute the basis for a finite-elements based design. Within this context, creep modelling constitutes a clear e...

Pressures on the current plastic waste management infrastructure has made growth of new sustainable recycling capacities crucial. Pyrolysis is an emerging thermochemical technology that may be utilised at a large scale to aid in reaching EU 2030 targets for waste. Plastic valorisation via this process could gain increased competitiveness with conventional methods through use concepts such as ‘D...

The vast majority of commercial polyolefins are semi-crystalline materials. Depending on the chemical composition and tacticity, their melting temperatures range from ambient to temperatures exceeding 160 C. Polyolefins form various crystalline structures that can be investigated with microscopic, spectroscopic and scattering techniques. When a semi-crystalline polyolefin is dissolved in a solv...

By introducing low-entanglement UHMWPE, the mechanical properties of polyolefins are improved to varying degrees. For polypropylene, lack interaction between UHMWPE and polypropylene results in an unsatisfactory reinforcement effect, disentangled state makes it easier for particles form defects driven by a chain explosion. In contrast, regarding polyethylene elastomer containing ethylene segmen...

Plastics are versatile materials used in a variety of sectors that have seen rapid increase their global production. Millions tonnes plastic wastes generated each year, which puts pressure on waste management methods to prevent accumulation within the environment. Recycling is an attractive disposal method and aids initiative circular economy, but recycling still has challenges overcome. This r...
