Description
ECP 225 is a magnetic compound based on special blends of magnetic additive compounded into PE in such a way as to optimise physical and magnetic properties during processing. Normally supplied in light blue colour.
APPLICATIONS
ECP 225 is recommended for packaging, handling, transportation applications where magnetic detection requirements exist.
Typical applications include:
- Film packaging
- Layflat tube
PROPERTIES
Specific Gravity 0.96 g cm-3
Flexural modulus 174.6 MPa
Flexural strength 4.51 Mpa
Izod Impact Strength (notched) DNB kJm-2
Tensile Strength 11.35 Mpa
Elongation @ break 78.1 %
RECOMMENDED PROCESSING CONDITIONS
MACHINE
It is recommended that an in-line reciprocating screw machine be used to injection mould ECP 225 but it is possible to process this material on plunger injection moulding machines.
EXTRUSION
Normal extrusion equipment should be used.
PROCESSING
Processing conditions will vary depending upon the machinery employed, but good quality product is achieved using moderate blow ratios with extruder temperatures from 120 – 160 degrees centigrade and die temperatures between 160 – 180 degrees centigrade.
MOISTURE
It is recommended that ECP 225 be dried prior to extrusion. Excess moisture may show as an inferior surface finish. Typically 2/4 hours at 80°C is adequate. Store in a warm dry place to avoid moisture.
USE OF REGRIND
Runners, sprues and scrap mouldings can be reground and blended with virgin material. Regrind additions should not exceed 10% by weight of the virgin material; otherwise some reduction in properties may be experienced.
DO NOT USE A MAGNETIC SEPARATOR IN THE MOULDING MACHINE AND HOPPER, THE GRAINS WILL SEPARATE AND STICK TO THE MAGNET!!
