Silicone tubes are the circulation and coating carriers for liquids, gases and other materials, and are widely used in modern industry, defense industry and daily necessities.
So how can silicone products reduce the hardness of silicone tubes? The hardness of finished silicone tubes that have reached product specifications cannot be changed. This is for vulcanized silicone. The main methods are as follows.
1. If you do not consider the cost, you can also increase the amount of oil in the silicone button, and just reduce the amount of carbon black appropriately. If the basic silicone material has not been produced, you must increase the amount of oil in the formula. The hardness of the finished silicone tube cannot be changed.
2. Either it depends on the material of the sealing ring silicone tube product, and it can continue to be vulcanized until it is over vulcanized. The hardness can also be reduced, but the performance of the product is not guaranteed.
3. An oven can be used to vulcanize the surface product back to its original state, thereby reducing the hardness. However, liquid silicone cannot guarantee the desired degree index.
