21. Polymers have both a melting temperature T m and a glass transition temperature T g. 22. The gas temperature can therefore be even higher than the melting temperature of the blade. 23. Because of its low melting temperature , it requires no sophisticated foundry equipment or specialized molds. 24. In general, increasing degree of polymerization correlates with higher melting temperature and higher mechanical strength. 25. Lower melting temperature enables polyethylene microspheres to create porous structures in ceramics and other materials. 26. Below their melting temperatures , most thermoplastic polymers ( polyethylene, nylon, etc . ) have rigidity. 27. The unsaturated fat is lowers the melting temperature to make vegetable oil a liquid ). 28. The low melting temperature of Wood's metal makes it unlikely this will harm the original. 29. ETFE has a relatively high melting temperature , excellent chemical, electrical and high-energy radiation resistance properties. 30. More recently, researchers developed nanocalorimeters that directly measure the enthalpy and melting temperature of nanoparticles.
