The capillary rheometer is an improvement on the more common melt flow index and melt flow rate machines as it has been found to better address more advanced moulding and extrusion applications. This more complex machine can be used to measure the flow properties of a material over the full range of rates, geometry, forces and temperatures during the actual conversion of thermoplastic materials from pellets into moulded parts. It also provides other applications, such as grading polymers, process control optimization, temperature sensitivity, thermal stability and processing effects.

The article informs about the use of cladding systems for the insulation of the exterior walls of the commercial and institutional construction in Canada. As stated, the modular exterior cladding systems acts as the first line of defense against water penetration while the air barrier is the second. The article informs about the types of cladding systems used recently including metal, composites, terracotta.
