Phase change materials (PCM) are attractive energy storage technologies due to their high energy storage density and the ability to reversible absorb and release thermal energy at a nearly constant temperature. Polymers and polymer-based eutectic mixtures are promising PCMs. This study aims to investigate heat properties (melting temperature ...

 Air suspension bellows is a rubber-based polymer material that needs to be used in heavyduty vehicles. The service life of the rubber and court cloth used as the bellows material changes due to the process. While premature damage to the bellows increases the risk of accidents, frequent replacements cause an increase in costs. In this study, ...

 The production of polyethylene blown films, which are used for the production of packaging, such as different types of bags and pouches, is a very complex process. With this procedure, the molten plastic mass is extruded through a ring tool and forms a thick-walled cylinder. The still heated and softened cylinder expands by blowing air into a...
