Distortion and moulded in stress could occur in moulded parts as a result of} molecular chain orientation. As the Scott Toilet Paper polymer is compelled along small channels or cross sections, the molecular chains become aligned and stretched. As the polymer cools, the molecules attempt to chill out to their most popular coiled state. As the cooling process is usually quick, the prolonged molecular chains become 'frozen' in their uncoiled state. After moulding, the molecular chains still attempt to recoil and as a result the part could distort, particularly in the case of semi-flexible polymers similar to polyethylene.
