LL
6201 XR is a high flow LLDPE grade,which offers a unique combination of
excellent processability and outstanding product properties.
Parts manufactured from LL 6201 XR have good gloss and offer advantages in,
toughness, environmental stress crack resistance, stiffness and heat
distortion resistance over comparable low density polyethylene items. These
properties have enhanced its use in making lids, thin wall
articles and general purpose houseware.
The superior properties of LL 6101 XR make itan ideal grade to substitute
lower melt index, low density resins and still achieve a significant
improvement in properties such as ESCR, gloss and stiffness. Another
outstanding feature is that articles molded from LL 6101 XR exhibit very low
warpage.
The intrinsically high stiffness of LL 6101 XR offers the advantage of
material savings by downgauging wall thickness whilst retaining top load
strength. The grade is also available in powder form (LL 6201 RQ) which is
used in compounding applications. |
LL 6201 XR can readily be processed on
commercially available injection molding machines. The optimum
conditions depend on many parameters e.g. application, mould design, etc.
but as a guideline the normal processing temperature should lie in the
range of 170-190 °C.
The grade shows an improved cycle time: the higher crystallization point
of linear LDPE and lits greater intrinsic stiffness versus LDPEallow mold
ejection at higher temperatures.
The LL6201 RQ powder version can be conveyed and fed through systems
designed to handle pelletized grades. However some minor modification may
be necessar.
Both resins are stabilized for protection against oxidation and yellowing
during processing under normal injection molding conditions.
