ManySilicone TubeAfter production, some items require spraying according to customer specifications, but the silicone tube surface will have many small particles after spraying. Is this due to the product itself or the negative effects of the spraying?
Firstly, the main factors causing the formation of particles on the surface of the spray silicone tube are as follows:
Silicone hoses were not cleaned properly before spraying, such as having fine hair or dust on the surface. If they are sprayed without inspection, it's likely that particles will be present.
2、Silicone TubeInsufficient vulcanization time in the mold extrusion molding machine results in the silicone tube not being fully cured, with raw material on the surface and also the formation of granules.
3. Overheating during vulcanization results in air bubbles on the surface of the silicone tube.
4. There is residual material in the silicone extrusion tube machine or the mold is damaged.
Additionally, the purpose of spraying silicone tubes is to make the product feel smoother and more comfortable to the touch. However, not all silicone tubes require spraying, as those like food-grade silicone tubes and medical-grade silicone tubes that come into direct contact with the human body have undergone relevant tested certifications. Silicone touch oil is a surface ink coating, which is non-toxic but should not come into direct contact with the human body. Therefore, when purchasing silicone tubes, consider the product's intended use to decide whether to apply the touch oil.
