Laboratory instruments.This manufacturer of a wide variety of rubber testing equipment has introduced the V15 Mooney viscometer viscometer Instrument for measuring the viscosity (resistance to internal flow) of a fluid. In one type, the time taken for a given volume of fluid to flow through an opening is recorded. , a compact, lightweight Mooney viscometer that requires neither compressed air compressed air, air whose volume has been decreased by the application of pressure. Air is compressed by various devices, including the simple hand pump and the reciprocating, rotary, centrifugal, and axial-flow compressors. nor a separate PC to operate. The V15 measures and records the viscosity of natural, synthetic or compounded rubber. It is also used to determine the curing rate during the early stages of vulcanization vulcanization (vŭl'kənəzā`shən), treatment of rubber to give it certain qualities, e.g., strength, elasticity, and resistance to solvents, and to render it impervious to moderate heat and cold. and can be set to perform both scorch and stress relaxation Stress relaxation describes how polymers relieve stress under constant strain. Because they are viscoelastic, polymers behave in a nonlinear, non-Hookean fashion.[1] tests. In addition, the company offers flex testers, rapid plastimeters, hardness testers, density measurement instruments, pocket durometers, thin film grips, hardness prediction software and much more.
