The rapid plastimeter is used to test the rapid plasticity (plastic initial value P0) and plastic retention (PRI) of natural and unvulcanized plastics (mixed rubber).

Principle:

The rapid plasticity value P0 is rapidly compressed by the main body to a cylindrical sample between two parallel compacts to a fixed thickness of 1 mm, and the test sample is kept under compression for 15 s to achieve a temperature balance with the parallel plate, and then tested. A constant pressure of 100 N ± 1 N was applied and held for 15 s. At the end of this phase, the measured thickness of the test is accurately measured by the observation instrument as a measure of plasticity.

The plastic retention rate PRI was measured by aging the sample at a temperature of 140 ° for 30 min through a high-precision special aging box, and the plastic value P30 was measured, and the PRI value was calculated by calculation.

The PRI value is a measure of the thermal oxidation of natural rubber, and a higher value indicates a better thermal oxidation resistance.

Features:

1. Direct electronic temperature control, fast heating and high precision

2. Direct loading with standard weights overcomes the shortcomings of instability and zero drift caused by the stress of the loaded electromagnetic spring.

Standards: 
ISO2007,  ISO2930
