The coefficient of linear expansion of PTFE is 10 to 20 times than that of steel, which is larger than that of most plastics, and its linear expansion coefficient changes very irregularly with temperature
Coefficient ukunwetshwa komugqa PTFE kuyizikhathi 10 kuya ku-20 kunaleso ensimbi, okuyinto emikhulu kunaleyo amapulasitiki kakhulu, futhi eqondile yalo izinguquko ukunwetshwa Coefficient irregularly kakhulu nge lokushisa
