The University of Queensland, in collaboration with the Non-Conforming Building Products (NCBP) Audit Taskforce in Queensland, Australia, have proposed a framework to provide a robust methodology to assess the fire hazard of cladding materials in existing buildings based on a thorough understanding of the relevant fire phenomena. Thermogravimetric Analysis enhances the robustness of the framework. Read here how the method is applied to evaluate the risk of external fire spread on buildings.
In the previous articles, focusing on thermal analysis under humidity, we have seen that thermogravimetric analysis and dynamic mechanical analysis help determine the influence of water on a material or substance. Thermomechanical analysis complements the analysis under humidity.
Water is one of the major parts influencing our climate. Our atmosphere is filled with water. We may not always be able to see it, but it interacts with us and our materials. Learn how thermal analysis helps identify water absorption and determine water content.
Sporting goods and toys for kids or pets are often made of flexible plastics. Some examples are sensory chewing toys, action figurines as well as balls of various kinds. A common polymer used for these applications is PVC (polyvinylchloride), because it can be made softer and more flexible by adding plasticizers. Therefore, they can evaporate or be rinsed out by saliva or sweat. Learn how to determine detect and identify plasticizers!
PMMI (Polymethacrylmethylimide) is a thermoplastic polymer. As it is an amorphous polymer, it features high transparency. The case study describes how thermal analysis methods can be employed to discover everything about the material.
Bringing cost, material, production process and quality successfully together is one of the key objectives in the injection molding industry. If the production process is not correct or if the material does not adhere to the specified requirements, low quality and thus scrap production is the consequence. Ideally, all of these four factors should be able to be managed in order to avoid scrap production. Thermal analysis methods offer valued approaches.
Thermoplastic parts can fail. This is no secret. However, when it has happened it is crucial to find out the reason for the failure of a part. Here is a short list of thermal analysis techniques and which questions they can answer in your failure analysis.
Industrial 3D printing processes create functional, end-use parts with mechanically isotropic properties and smooth surface finishes. Read how Prof. Dr. Tim Osswald, Alec Redmann and the team at the University of Wisconsin-Madison worked together with the California-based company Carbon Inc. optimized the thermal curing cycle of EPX 82 resin used in the their Digital Light SynthesisTM (DLSTM) process.
Every delivery of thermoplastic material includes a certificate. The European Norm EN 10204 specifies different types of control documents. However, the data contained in the free-of-charge documents are often not sufficient enough. Obtaining specific material data of a delivered batch is tied to additional cost. Read how to become the owner of your material data.
Today, no industry lives and breathes more by the saying “Time is money” like the automotive industry. Car manufacturers pass tough improvement targets on to their suppliers of parts and components. Striving to meet constantly changing demands is often accompanied by new assessments of thermoplastic materials. Learn why thermal analysis is crucial in this process.
