THERM0PLASTIC ELASTOMERS STRUCTURAL WEAR CONDUCTIVE COLOR FLAME RETARDANT Resin Selection
The Dilemma 60 Thermoplastic Resins + 100 Additives = 1000 s of Potential Compounds Which 1 Do I Choose For My Application????
Plastic Selection Process Step 1 -- Use Resin Morphology Step 2 -- Use Thermal & Cost Requirements Step 3 -- Fine Tune & Special Features
Morphology The form and structure the molecules of a polymer take upon solidification Amorphous Semi-Crystalline
Morphology Amorphous Semi-Crystalline Compare Molecular Packing (Shrinkage) Chemical Bonds (Chemical/Abrasion Resistance) Melting Characteristics (Flow) Light Refraction (Opacity)
Morphology Characteristics Low Shrinkage Low Warpage Tight Tolerances Transparency Mold Flow Ease Chemical Resistance Wear Resistance Amorphous Semi-Crystalline
Morphology Characteristics Amorphous Semi-Crystalline Low Shrinkage Low Warpage Tight Tolerances Transparency Mold Flow Ease Chemical Resistance Wear Resistance Lens? Fuel Float? Lamp Housing? Tool Housing? Pulley? Precision Printer Chassis? Intake Manifold? Grease Fitting? Laptop Cover?
