Silicone finished products are famous for their superior elasticity and super high tear strength. Products made of silicone materials have long service life, comfortable hand feeling and flexible texture, which are incomparable to products made of other materials. Therefore, they are also widely used in many fields. In the production process of silicone products, it will be found that silicone finished products will appear brittle, which affects the production, and the brittle silicone finished product in the service life also can not meet the requirements, then, what are the elements of the occurrence of the brittle silicone finished product.
First, the structure of the finished silicone product or the design of the mold causes the product to split briefly, and the product structure or the design of the mold is unreasonable, causing the finished silicone product to split briefly during molding. The solution is to modify the structure of the product or the mold to end the improvement, for example, slightly thicken the excessively thin local area, slightly round the right angle, etc.
Second, the molding temperature is too high or the curing time is too long, resulting in brittle silicone products, the solution: lower the temperature to control the curing time.
Third, the secondary sulfur ventilation is not good or the temperature is too high to form a silicone finished product brittle, silicone products factory solution: carefully adjust the secondary sulfur ventilation and control the temperature.
Fourth, the material of silica gel itself and the elements of the glue itself constitute the primary elements of the brittleness of the finished silica gel product. Usually, the brittleness of the finished silica gel product is due to the poor quality of the glue itself and the tear strength cannot reach the request. In addition, many finished silica gel manufacturers now fill the glue with silica powder to reduce the cost in order to reduce the cost, which makes the glue whose original tear strength cannot meet the requirements more brittle.
How to choose a good silicone sleeve.
1. Material: It is divided into pure silicone and ordinary silicone. Pure silicone has good toughness and will not turn white when stretched hard, while ordinary silicone rubber products are easy to break, and will turn white when pulled lightly, indicating that there is silicon powder with cheap value added in it, which is shoddy.
2, feel: good feel smooth, poor feel sticky.
3. Appearance: The good color is uniform, the poor surface is rough, the color is different, and even impurities can be observed.
4. Taste: Silicone has more or less peculiar smell, and poor silicone has a particularly strong and unpleasant taste.
Secondly, the different molds, mold design is reasonable, fine degree, also different, which laid the silicone sleeve finished product quality, ease of use.
