Between 20g 　　c、The transparency surmounts the ordinary glass; there are 93% of the penetratey rates and splendor of having crystal glass. (Time of changing color: Begin to turn yellowish in 2 years) 　　d、Methacrylic is passed because of hot shaping, stiff shaping temperature is in 150 ℃- 160 ℃met acrylic surface hardness , strength of board equivalent to aluminium is hard to but can't stand irons than other plastic, the pottery can be regarded as the hard thing to rub and knock out 2、What is toughened glass? 　　Usually, the enclosure uses is the toughened glass using the physics method to process, namely the craft of cooling suddenly after intensifying and heating to certain temperature of glass. The toughened glass after being has changed the crystal structure within the glass, has improved the hardness of surface, to is it resist impact degree , bending strength into raise than the ordinary glass by 3-5 times to toughened glass. When influencing by external force the damage of presenting, the glass presents the small chip which do not have the pointed ness glass, the injury degree to the human body is obviously reduced.
