imple measuring procedure allows anyone to use it easily

Some of the features are:
Densimeter with high accuracy of density resolution of 0.0001g/cc
Substantial function of SOlid and Liquid measurements only about 20 seconds to measure
Suitable for plastic pellets, film, rubber, fabric, etc.
Capable of measuring volume variation factor
Capable of measuring readily floating samples such as urethane sponge, and wood

The apparatus is widely used for deltermining the plasticity and recovery of silicones and unvulcanised rubber compounds.

The test consists of compressing a sample of 2.0cm³volume between two parallel plates and measuring the compressed height after a specified period.

The plastimeter features two platens, a lower platen that forms the base of the instrument, and an upper platen, which can be conveniently raised and lowered by a handle.

The test commences when the upper platen is gently lowered onto the sample with a force of 49N. The sample height is taken at regular intervals, commonly 3 or 10 minutes using a dial gauge measuring in 0.01 mm graduations.

At the end of the test the result is converted to a Williams Plasticity Number by multiplying the sample height by 100.

Elevated Temperatures
For measurements at elevated temperatures (normally 70C or 100C) the sample is heated in an oven for 15 minutes before undergoing the plasticity test. For this purpose, under model ref. P2/1, Wallace offer a Plastimeter complete with Laboratory Chamber-suitable for temperatures up to 150C.

Recovery Test
In the recovery test, the height of the sample is measured after it has been removed from the plastimeter and allowed to recover for a specified period.

The Wallace Bench Thickness Gauge (ref. S4/13) must be used for such measurements as the gauge specification is tightly controlled by the relevant standard.

Accessories
Plastimeter with Laboratory chamber P2/1
Bench thickness Gauge S4/13
Rotary sample cutter 16mm dia P2/10

Machined to a very high quality standard, these fixtures measure the residual strain in a rubber sample after it has beencompressed for a specified period and then allowed to recover. Samples of either 13mm or 29mm diameter are placed between the plates and the bolts tightened. Spacer rings around the bolts control the compressive strain applied.

Wallace offer single daylight (i.e. 2 plates), double daylight (3 plates) and triple daylight (4 plates) versions. When ordering please specify wheter C3 (BS) or C4 (ASTM) models are required and specify the number of daylights (plates).

Preparation of Test Pieces

For use with a bench drill to produce parallel sided test samples, two rotary cutters are available 13mm diameter & 29 mm diameter.
