Plastics Technology’s Materials Know How columns in 2025 provided insights into these essentials, breaking down concepts like molecular weight, which influences viscosity and mechanical properties, and entanglements that restrict chain movement beyond just molecular weight. Key highlights included polymer comparisons: - PC/ABS for balancing impact strength, stiffness, and processability. - PC/PBT for impact strength, dimensional stability, and chemical resistance. - PPO versus PA66, contrasting amorphous and semicrystalline benefits in toughness and tailorability. - POM versus POK, evaluating strength, wear resistance, and dimensional stability in engineering thermoplastics. Additional topics covered polymer sel...
