Materiale termoplastice• Care se inmoaie sub actiunea caldurii si devin plastice (putandu-

se modelata in forme diferite), iar prin racire se intaresc.• Aceste procese este revelsibile, adica materialele pot fi incalzite

si remodelatede nenumarate ori,fara sa se degrada.• Din acest motiv materialele termoplastice sunt reciclabile.

MATERIALELE PLASTICE sunt materiale organice in stare solida, formate din substante naturale sau sintetice.Din ele se obtin produse, prin deformare plastica la cald.

Materiale din cauciuc sintetic

• Se obtine din unele hidrocarburi gazoase(de exemplu, gaze de rafinarie). In stare brut,

cauciucurile sintetice au unele proprietati scazite-de aceea se folosesc diverse materiale de adaos (negru de fum, plastifianti, acceleratori, agenti de vulcanizare), care se imbunatateasca aceste proprietati.

CAUCIUCUL este un produs organic, care poate fi natural sau artificial.

STICLA CRISTAL• Sticla este un material obtinut prin racirea rapida a unei

topituri pana la solidificarea topiturii intra mai multe componente.

• Este alcatuit din-Nisipul cuartos-se gaseste in natura sub forma de zacaminte mari si are ca p rincipal component .

-Soda calcinta-este introdusa in amestecul de materiale prime sub forma granuala si are ca scop reducerea temperaturiide topire a nisipului.

-Calcarul-este foarte raspindit in natura, are culoarea alba cu nuante de roz.

-rolul sau este de a face sticla rezistentafata de apa si de alte substante chimice.

Proprietati• Proprietatile fizice-luciu metalic -culaore -fuzibilitatea -conductibilitatea -termica -electrica -magnetismul Proprietati chimice-rezistenta la coroziune -refrectaritatea Proprietati mecanice-elesticitatea si plasticitatea

-duritatea Proprietati technologice-fluiditatea -malabilitatea -ductibilitatea -sudabilitatea
