Polyamide
Posankha ma monomers enieni, munthu amatha kukwaniritsa polyamide yowoneka bwino komanso yowonekera kwamuyaya. Ma crystallite ndi ang'onoang'ono kwambiri kotero kuti samamwaza kuwala kowoneka, ndipo zinthuzo zimawoneka zowonekera m'maso mwa munthu - chinthu chodziwika kuti microcry stallinity. Chifukwa cha crystallinity yake, mawonekedwe a microcrystalline amakhalabe ndi zinthu zofunika monga kukana kupsinjika maganizo - popanda mitambo. Mlingo wa crystallinity ndi wochepa kwambiri, komabe, kuti ulibe vuto lililonse pa khalidwe la shrinkage la ziwalo zowumbidwa. Imakhala ndi shrinkage yofanana ya isotropic ngati zida za amorphous.
Ndi polyamide yotsika, yowoneka bwino yopangira jakisoni.
