1 Section 1 – Introduction
1.1 Overview
The Tinius Olsen MP1200/MP1200M Extrusion Plastometer (Melt Flow Indexer) with
microprocessor-based Model MP1200 Controller/Timer, is used for measuring the flow rates
of thermoplastics. The unit is a dead-weight piston plastometer with which the extrusion rate
of thermoplastic materials through an orifice of specified dimensions is determined under
prescribed conditions of temperature and pressure in accordance with ASTM Standard Test
Method D1238 & ISO 1133-1 & 2. With minor procedural or equipment modifications, the
MP1200 can also meet BS 2782, DIN 53735, JIS K7210 and other similar standards;
including ASTM D2581, D3364, D4203, D4507 and D4550 (a special orifice is required for D
3364). Other methods, such as D2116, D3159, D3275 and D3307, require the optional
corrosion resistant cylinder, orifice and piston foot.
A basic machine (MP1200) may be used for Procedure A - Manual Operation. A weight (s)
will be required to apply the test load. The amount of load is material dependent, so
weights are sold separately. With the addition of optional accessories (PPDT), Procedures
B & C (ASTM D1238 Procedure C) - Automatically Timed Flow Rate Measurement for Melt
Flow Rate (MVR) and/or Melt Volume Rate (MVR) can be performed.
The MP1200M is equipped with a motorized Weight Lifting/Lowering Device (WLD). It can
also be used for Procedures A, B, C & D when equipped with the optional PPDT (Flow Rate
Ratio Attachment is required for Procedure D). A weight(s) will be required to apply the test
load. The amount of load is material dependent, so weights are sold separately.
CAUTION: This instrument has been designed to determine the flow rate and other thermal
processing properties of polymers. It is not intended for any other use. Any attempt to use
this instrument in any fashion other than its intended use may void the warranty, damage the
machine and/or harm the operator.
1.2 Heavy Duty Construction
Sturdy design includes housing for temperature and timing controls, rugged uprights for
supporting the hardened steel test cylinder, which is heated by a precision three zone
controlled band heater, is insulated and jacketed in an aluminum housing. A set of
operating tools, bottom release orifice feature, mirror and a tool rack are included with each
machine. The unit is semi-portable and contains provisions for leveling the cylinder.
1.3 Touch Screen Display
The touch screen display allows the operator to interact with the unit to easily configure test
programs, run tests, and view results. Testing programs can be stored for recall or
necessary values can be entered at test time. Programs can be set up and stored for a
variety of tests.
