This contraction is partly due to the difference of density of polymers from the melt state and the cooled, rigid state. Polyethylene terephthalate (PETE or PET): PET is the most widely produced plastic in the world. In these joints, a plastic or metal component is assembled onto a plastic base. • Plastics melt or cure at relative low temperatures • Plastics require less energy to process than metals • Raw materials most commonly are pellets, powders • Also available as sheet, plate, rod, and tubing (produced by extrusion, etc.) '�o�õ_ri�Ɇ�o�V�h;.E� ���hc�L���>��9]^�\������0�ln�馼Sy�ʓj�����:�Ql�>��d�u����N���5����Ƹ-��qž��9z l���Dv�q4�C �;�`V[I�8$⺿��8��`�:�v]ޱi� �맹��3��=JD ��+�( �]�Ë�w�K/´�j0��i�C���. 0000018180 00000 n 0000009412 00000 n Items such as disposable coffee cups, plastic food boxes, plastic cutlery and packing foam are made from PS. This property of plasticity, often found in combination with other special properties such as low density, low electrical conductivity, transparency, and toughness, allows plastics to … THERMOPLASTICS Material Properties of Plastics 1.1 Formation and Structure The basic structure of plastics (or polymers) is given by macromolecule chains, formulated from monomer units by chemical reactions.
