What is the difference between silicone and plastic?
Sep 05, 2019
Silica gel and plastic: one is a thermosetting polymer, one is a thermoplastic polymer. When the silica gel is heated, it cannot be repeatedly molded. It does not dissolve in the solvent. The plastic can flow and deform when heated. It can maintain a certain shape after cooling, and it is easy to squeeze. Forming processing such as injection, injection or blow molding, and repeated heating and cooling hardening within a certain temperature range.
1. Food grade silicone is odorless and most of the plastic has odor;
2. Silica gel is more chemically stable than plastic;
3. Silica gel can be degraded, plastic can not;
4. Silicone is resistant to aging and has a long service life, and the plastic is relatively poor;
5. Silicone performs better than plastic in terms of anti-shock, fading and tear resistance;
6. Temperature resistance: silicone resistant to high and low temperature (-40 ° C -230 ° C), plastic (100-150 ° C);
7. Silica gel in terms of combustion performance: non-flammable; and plastic is flammable and produces harmful substances.
