POKETONE Polymer M330A
POKETONE Thermoplastic Polymers are
aliphatic polyketones, a revolutionary new
class of semi-crystalline thermoplastics.
POKETONE Polymer M330A is a high
flow injection moulding grade with
mechanical properties which classify it as an
engineering thermoplastic.
This grade exhibits very good processability,
good impact resistance, high resilience and
good creep performance. POKETONE
Polymer M330A can also withstand short
term exposure to elevated temperatures.
Moreover This polymer exhibits high
resistance to hydrocarbons, solvents, salt
solutions, weak acids and weak bases.
POKETONE Polymer M330A is a high
flow, low-viscosity polymer that should be
considered for mouldings with long flow paths
or thin walls. This grade is very easy to
process on standrad injection moulding
equipment.
Cycle times are generally short. Parts show
good mould definition with glossy mar
resistant surfaces. POKETONE Polymer’s low
moisture sensitivity means that no conditioning
of parts before assembly or use is necessary.
Applications for POKETONE Polymer
M330A may be found in the automotive,
electrical, electronics, industrial and consumer
applicance markets.
