Did you know that with the right formulation, you can achieve
properties that are as good or better than that of PA 6,6 using materials such as PA 6, PK, PBT/PET, PP,
polymer blends and even post-industrial recycled blends?
HOW ALTERNATIVE
POLYMERS COMPARE
TO PA 6,6
PA 6 | POSSIBLE APPLICATIONS:
Automotive, Industrial, Consumer & Sporting Goods
Wider processing temperature range
Better surface quality
Better weathering resistance
Shorter conditioning time—nearly half that of PA 6,6
Lower temperature resistance
Slightly lower chemical resistance
Higher water absorption
Lower stiffness/wear resistance
PK | POSSIBLE APPLICATIONS:
Automotive, Consumer & Sporting Goods, Industrial,
Electrical & Electronics
Lower CO2 emissions in production
Better hydrolysis and chemical resistance
Comparable dimensional stability
Inherently lubricious for reduced wear and friction
Easier to mold
Cost competitive
Lower short- and long-term thermal performance
Harder to color
More limited process window
PBT/PET | POSSIBLE APPLICATIONS:
Electrical & Electronics
Lower water absorption
Slightly higher rigidity/stiffness (for PBT)
Better abrasion resistance
Slightly better electric resistance
Lower toughness properties
Higher density
Lower short- and long-term temperature resistance
Lower hydrolysis resistance
PP | POSSIBLE APPLICATIONS:
Automotive, Consumer Goods,
Lightweighting Applications
Lower water absorption
Slightly better chemical resistance
Lower density
Cost effective
Fiber reinforced PP can achieve similar or
better mechanical properties to PA 6,6 GF30
Reduced rigidity/stiffness
Much lower abrasion resistance
Lower electric resistance
Reduced short- and long-term temperature
resistance
PC/PBT & PC/PET BLENDS |
POSSIBLE APPLICATIONS: Automotive Interiors,
Consumer Goods, Household Appliances
Higher impact strength
Good scratch resistance
Good wear resistance
Lower mechanical properties
Higher brittleness
Narrow processing temperature range
PA 6,6/PET BLENDS |
POSSIBLE APPLICATIONS: Automotive, Industrial,
Appliance, Electrical & Electronics, Applications Where
Low Water Absorption is Required
Reduced water absorption—up to 40%
Slightly higher mechanical properties in the conditioned state
Slightly lower temperature resistance
Slightly lower chemical resistance
Narrow processing temperature range
PA/PP BLENDS | POSSIBLE APPLICATIONS:
Automotive Interiors, Electronics,
Consumer & Sporting Goods
Good adhesion to polyolefin-based TPEs
Low permeability of water
Good processability
Lower density
Lower temperature resistance
Lower mechanical properties
POST-INDUSTRIAL RECYCLED SOLUTIONS
(PA 6,6/PA 6/PP) |
POSSIBLE APPLICATIONS: Automotive Accessories,
Industrial, Consumer & Sporting Goods
Between 50-80% recycled content
Good processability
Cost effective
Reduced chemical resistance
Wider range of mechanical specifications
Potential for slightly lower mechanical properties
