Plastics & Polymer Testing Instruments

Plastics & Polymer Testing Instruments Lloyd Instruments offers the complete solution for polymer testing applications, from raw material to finished product. Our established range of Davenport™ polymer test instruments, specified in many international testing standards, allow critical polymer parameters to be determined, including melt flow index, melt flow rate, melt volume rate, intrinsic viscosity of PET, impact strength of plastic film, density measurement, HDT and VICAT. In addition, Lloyd Instruments manufactures a wide range of materials testing machines for evaluating the mechanical...

HDT/VICAT Instruments The Davenport HDT/VICATPlus instrument is designed to determine the temperature deflection of thermoplastic samples to national and international standards. The unit consists of a temperature controlled oil bath, with six selectable testing stations, which may be configured for either HDT or VICAT test methods. The weight loading mechanism and test fixture mountings are designed as a single unit, which safeguards the operator by preventing contact with the heating medium. • Performs tests to national and international standards: VICAT: EN ISO 306, ASTM D1525-98 1/10, BS...

Inclined Planes The Davenport Inclined Plane is ideal for accurate, simple and quick checks on coefficients of friction. The method involves increasing the angle (up to 60°) of inclination of a plane surface covered with the test material. A free sled, also covered in the material will start to slide at the point at which gravitational force overcomes the static friction between the two. • Designed for determining the coefficient of friction • Inclination is marked off in tangents for direction readings of static and kinetic coefficient of friction • Simple set up, operation and maintenance free...
