These include melt flow index (MFI), melt flow rate (MFR), melt volume rate (MVR), intrinsic viscosity (IV) and melt viscosity (MV) of PET, impact strength of plastic film, density measurement, HDT and VICAT.
Testing may be carried out throughout the entire manufacturing cycle of polymer products.
The precision-engineered manual MFI-9 and automatic MFI-10 melt flow indexers are specifically designed for determining melt flow index, melt flow rate and melt density/viscosity of polymers to ISO1133 and ASTM D-1238 Methods A and B.
Both have excellent temperature control and provide outstanding accuracy and repeatability of results.
The Davenport melt viscometer offers significant cost and environmental benefits for PET testing, avoiding the need to handle and dispose of toxic solvents.
It has become a popular choice with resin producers and processors worldwide to monitor intrinsic viscosity and melt viscosity from incoming resin to finished product.
The Davenport HDT/VICATPlus has been designed to determine the temperature deflection of thermoplastic samples to national and international standards.
These are: VICAT to EN ISO306, ASTM D1525-98 1/10, BS 2782 Part 1: Method 120C 1990; and HDT to EN ISO75-1 and 75-2, ASTM D648-98C.
Other products covered in the brochure include density measuring columns, falling dart impact testers and inclined plane friction testers.
Density measuring columns are used for determining the density of solid plastics, and the falling dart impact tester provides a quick and simple method for measuring the impact resistance of thin flexible materials such as plastic films, plasticised papers and composite sheets.
The Davenport Inclined Plane is ideal for accurate, simple and quick checks of the coefficients of friction.
Also available is the new Lloyd Instruments FTPlus instrument, a dedicated friction tester conforming to the requirements of ASTM D1894, ISO8295 and TAPPI T549.
The tester includes these standards as user configurable tests, with a further seven available for user custom configuration.
