Plasticity

Product catalog summary

Overview: The document discusses innovations in rubber testing, focusing on the MonTech RP 3000 Rapid Plastimeter and the MonTech PO 3000 ageing oven. These instruments are used to measure the plasticity and viscosity of polymers and unvulcanized rubbers, particularly for determining the Plasticity Retention Index (PRI) of raw natural rubbers.

MonTech RP 3000 Rapid Plastimeter:

Measures plasticity or viscosity of polymers and unvulcanized rubbers.
Operates within a temperature range of 25°C to 200°C, allowing for variable test conditions.
Uses a modified parallel plate compression principle with automatic conditioning and load periods.
Features include automatic calibration, platen parallelism alignment, and a strong aluminum and stainless steel frame for precision.
Optional MonPlast software provides full P0 and PRI evaluation, plasticity curve display, and batch report generation.

Plasticity Retention Index (PRI):

Measures resistance of raw natural rubber to oxidation.
Calculated by comparing plasticity before and after ageing at 140°C for 30 minutes.

Test Procedure:

Sample preparation involves a mechanical specimen cutter and tissue paper to prevent sticking.
Automatic test sequence with digital display of results via optional software.

MonTech PO 3000 Ageing Oven:

Used for ageing rubber samples according to international standards.
Features a robust stainless steel case with an aluminum block and four chambers.
Maintains a temperature of 140°C with a PID controller and includes a warning system for temperature deviations.
Equipped with independent timers, a beeper, and a monitoring system for each chamber.

Technical Specifications:

Standards: BS 903:Pt A59, ISO 2007, ASTM D 3194.
Platen sizes: 10 mm, 7.3 mm, and 14 mm diameter.
Compressive force: 100 N.
Data interface: RS 232, with optional MonPlast software and data printer.
Ageing oven capacity: 48 samples, with adjustable air exchange rate.

MonTech RP 3000 Rapid Plastimeter for Polymers and Natural Rubber The MonTech Rapid Plastimeter measures the plasticity or viscosity of polymers and unvulcanised rubbers. The test is simple, clean and quick. The instrument is typically used in conjunction with the MonTech ageing oven for plasticity testing to determine the Plasticity Retention Index (PRI) of raw natural rubbers. The variable temperature range from 25°C to 200°C for easier to read with freely programmable conditioning and load times allow a convenient characterisation of the flow behavior of natural and synthetic rubbers at variable...
