- The shape is neat and beautiful, the material is soft, smooth and does not hurt the hand. It has the advantages of good touch, not easy to absorb water and long service life.
- Heat resistance: softening starts at 180 ° C and begins to melt at 215 ° C – 220 ° C.
- Cold resistance: It can be used at a low temperature of minus 20 ° C, and the lower the temperature, the stronger the tensile force, but the durability is reduced.
- Drug resistance: 50% salt soda water, 28% ammonia, 2.5% hydrochloric acid, and 3.5% nitric acid can work normally.
