The difference between silica gel and plastic: \x0d\ 1, nonpoisonous and tasteless: silica gel is not available, but most plastics have it; \x0d\2。 Physiological inertia and chemical stability: silica gel is high, plastic is average; \x0d\3。 Environmental degradation: silica gel can, but plastic can't; \x0d\4。 Anti-aging and service life: silica gel can, but plastic can't; \x0d\5。 Flexibility/elasticity: excellent silicone, poor plastic; \x0d\6。 Anti-skid, shock-proof, elastic, insulating, tear-resistant and fading-resistant: excellent silicone, poor plastic; \x0d\7。 Temperature resistance: silica gel can withstand high and low temperatures (-40℃-230℃), and plastic (100- 150℃)\x0d\8. Combustion performance: silica gel is nonflammable and does not produce harmful substances, while plastic is flammable and produces harmful substances;
