Plastiklarning qattiqligi polimerlarning tuzilishi va boshqa materiallarning qo'shilishiga bog'liq. Masalan, plastmassalarni yumshatib yuborish plastmassalarni yumshoqlashtirishi mumkin, kuchlantiruvchi materiallarni qo'shish esa ularni qattiqlashtirishi mumkin. Plastiklarning qattiqligi ham qayta ishlov berish va shakllantirish usuli tufayli farq qilishi mumkin.
