Chinese Professional air blown fiber - Polyamide – GELD Detail:

By selecting specific monomers, one can achieve a crystallizable and permanently transparent polyamide. The crystallites are so small that they do not scatter visible light, and the material appears transparent to the human eye—a property known as microcry stallinity. Because of its crystallinity, the microcrystalline structure retains important properties such as stress cracking resistance — without clouding. The degree of crystallinity is so negligible, however, that it has no adverse effect on the shrinkage behavior of molded parts. It undergoes a similar isotropic shrinkage like amorphous materials.

It is a low-viscous, permanently transparent polyamide for injection molding.
