In the previous silicone industry, people may only know industry terms such as mold silicone, hand plate silicone, pad printing silicone, etc. The new term foamed silicone is unheard of in the industry. So what are the foamed silicones used for? Are there any unique features? Take a look at the answers below with questions.
First of all, foamed silica gel, also known as addition-type silica gel, is composed of silica gel and curing agent in a ratio of 1:1. It becomes a soft elastic material after white vulcanization. It is an environmentally friendly material, and the products produced are non-toxic. Odorless, safe and hygienic. Foamed silica gel can be used to make soft silicone rubber products such as human body, patches, insoles, anti-skid pads, shoulder pads, etc. The tear strength is 55Kn/m; the fire rating is 94v-0; the temperature resistance range is -40- 220c; ductility is 100%. Moreover, it has excellent electrical properties and chemical stability, water resistance, easy operation, non-toxic and tasteless, low linear shrinkage, and weather aging resistance. If we use foamed silica gel, the recommended ratio is: curing agent raw material 1:1, curing temperature 120°C, curing time 13-20min. Do not contact with any other condensed silica gel, otherwise it will cause poisoning of the curing agent, resulting in the phenomenon that the silica gel will not cure, and organic tin catalysts, acids, alkalis, water, sundries, sulfur, phosphorus, and other organic substances can affect The curing of silica gel should not be mixed or contacted with these substances during use.
How to use foamed silica gel:
1. All tools, utensils, containers and other items in contact with liquid silica gel must be clean, and avoid contact with phosphorus (P), nitrogen (N), sulfur (S) compounds and metal organics, otherwise the product catalyst will fail and non-vulcanization will occur.
2. Mix the curing agent and raw materials according to a certain ratio, and stir for 2-3 minutes to ensure that the materials are mixed evenly
3. Fully stir the raw materials before use to avoid uneven distribution of some raw materials caused by storage
4. The recommended ratio is curing agent: raw material = 1:1, curing temperature: 120°C, curing time: 13-20 min
The birth of foamed silica gel can be said to be a major development and progress in the silica gel industry. It is also one of the products and projects that major silica gel entrepreneurs compete for. Getting a new product and a new industry term can be said to affect this company. direction of development.
