Crystallisation

During the long annealing phase of up to 20 hours the polymer chains align themselves and form a crystalline, homogeneous and stress-free structure with spherolite structures. This is the secret why HAWAMID 12G differs from other plastics. Depending on the production process, PA 6 reaches a crystallisation degree of between 10% and 60%. HAWAMID PA 12G can obtain up to 98% crystallinity. The higher the degree of crystallisation, the better the capacity to withstand mechanical, chemical and thermal stress. Dimensional stability increases and water absorption decreases to the lowest value amongst all polyamides.
