What are the parameters of silicone utensils?
1. Tear strength.
Resistance to the expansion of a cut or score when force is applied to a cut sample. Even if it is cut and placed under extremely high torsional stress, the thermally vulcanized solid silicone rubber can not be torn. The tear strength of thermally vulcanized solid silicone rubber ranges from 9 to 55 kN/m. The tear strength of fluorosilicone rubber ranges from 17.5-46.4 kN/m. Liquid silicone rubber has a tear strength range of 11.5-52 kN/m.
Typically referred to as the “Ultimate Elongation at Break” or the percent increase relative to the original length when the sample breaks. Thermally vulcanized solid silicone rubber typically has an elongation range of 90 to 1120%. The general elongation of fluorosilicone rubber is between 159 and 699%. The general elongation of liquid silicone rubber is between 220 and 900%. Different processing methods and the choice of hardener can greatly change its elongation. The elongation of silicone rubber has a lot to do with temperature.
3. Operation time.
The operating time is calculated from the moment the colloid is added to the vulcanizing agent. There is no complete boundary between this operation time and the latter vulcanization time. The colloid has undergone vulcanization reaction from the moment the vulcanizing agent is added. This operating time means that the 30-minute vulcanization reaction of the product can not affect the quality of the finished product. Therefore, the more time saved in the product operation process, the more beneficial to the finished product.
