Understand the process and material selection requirements of silicone tableware

Dongguan Tufeng Rubber Co.,Ltd | Updated: Nov 06, 2018

Silicone tableware refers to tableware used in the production of silicone materials. Non-toxic, tasteless, high temperature resistant, molded with food grade silicone.


Compared with ceramic, plastic and metal tableware, silicone tableware is compatible with temperature. Whether the food is cold or hot, it can protect the temperature of the food itself, reduce the temperature change and loss, and put it in a silicone bowl or basin for a period of time. The food can also maintain its original temperature and will not pass the corresponding temperature to the user during use. And the special nature of the silicone material itself is different from other materials, so that the products made by it have amazing effects. For example, the silently filled food utensils will not produce harmful substances after being cooked at a high temperature. Moreover, the tableware can be folded, kneaded, and can be turned over, and does not occupy space in the pocket, nor does it absorb oil. It has a desiccant function and does not mold and change due to long-term storage.


Because of the temperature resistance of silicone rubber, it can withstand temperatures up to 240 ° C without deformation, and does not cause hardening at -40 ° C. Therefore, this is a multi-productive product, very practical, we can easily put in without classification. Inside the microwave oven, you don't have to worry about melting, aging and yellowing, and it is easy to clean. It can be used less or even without chemicals. It is very practical and convenient, and it is suitable for use in life.


In real life, we have a variety of different materials, ceramics, plastic glass and stainless steel, but in use we will find: ceramic tableware shape design is very beautiful, people feel very at first sight Ok, but the ceramic itself is too hard, so if you accidentally touch it, it will be broken or broken. At that time, it can only be thrown away. Although the plastic tableware does not appear ceramic, it has been used. Friends know that plastic tableware is difficult to clean after it is dirty. Sometimes it is necessary to go to the hot water and detergent. Everyone knows that the detergent contains more or less chemicals, and it is not good to use more. The last thing to say is the stainless steel tableware. The stainless steel meal looks beautiful and durable, but if it is not properly protected, it will easily rust, and it is not allowed to place salt, soy sauce and vinegar for a long time. It is also not possible to wash with baking soda, bleaching powder, sodium hypochlorite or the like. Because these substances are strong electrolytes, they will react electrochemically with stainless steel, so the following factors should be noted in raw material selection and process:


1. Environmental protection requirements: Silicone tableware products should pass the corresponding international environmental protection requirements, such as: REACH, RoHS, halogen, LFGB or FDA;


2, material properties requirements: the need for high anti-yello odorless bridging agent (vulcanizing agent) or platinum bridging agent (platinum vulcanizing agent) (according to different customer requirements), high temperature resistant color masterbatch, resistant to secondary vulcanization Primer (products containing silica gel), can pass the environmentally-friendly fumed silicone rubber, especially when using silicone rubber release agent, otherwise it will not meet the food-level testing requirements;


3, process requirements: In order to protect the product environmentally safe, all silicone rubber tableware products should be subjected to secondary sulfurization for 2-4 hours under the condition of hot air flowing at a temperature of 180 ° C - 200 ° C, such as the use of platinum bridging agent for vulcanization molding In the case where the measurement can pass the LFGB or the FDA, the secondary vulcanization time can be appropriately shortened.
