Overview
Polytest Line — what it covers
The Polytest Line is COLLIN's measurement and quality-control range — the instruments that tell you whether a polymer, a recyclate or a finished film is actually within spec.
It splits into three groups: melt viscosity measurement (rheometers and online viscometers), contamination and gel measurement (manual and automated pressure filter test), and optical film inspection.
The range
8 machine families in the Polytest Line
Automated Pressure Filter Test
The automated pressure filter test is used for determining quality differences in a polymer caused by agglomerates, insufficiently dispersed fillers or contaminations…
Film Inspection FI
The COLLIN film inspection system is an extremely high-quality test line, which enables a definition of up to 10 error classes by means of 14 error criteria.
Rheometer
Rheometers serve in determining the melt viscosity, thus they are an essential element of the permanent quality control during polymer processing.
Online Viscometer
The online viscometer is used for continuous control of the melt viscosity of a production extruder.
Manual Pressure Filter Test
The manual COLLIN pressure filter test is used for determining quality differences in a polymer caused by agglomerates, insufficiently dispersed fillers or…
Pressure Filter Test AFT MP-E
The fully-automated COLLIN pressure filter test with autosampler enormously reduces the down times, the personnel costs and enables high reproducibility.
Film Inspection COFICOS
The COFICOS line is suitable for tests under adverse conditions close to a production line.
