What kind of silicone products are of high quality?

1. Whether the self-healing edge of the product feels rough or not, the size of the mold closing line determines the workmanship of the product mold, and the mold workmanship determines the overall effect of the product. Self healing is very important!

2. The vulcanization effect of the product and the uneven hardness and softness of the product feel; Poor stretch resilience and rebound effect; It is related to the manufacturer's vulcanization time and the issue of raw materials.

3. The color and odor of silicone products depend on the uniformity of the manufacturer's mixing process. The longer the time, the better the color saturation.

4. Silicone raw materials are non-toxic and odorless, but when sulfurizing agents are added to the raw materials and subjected to high-temperature hydraulic molding by silicone manufacturers, a glue smell may appear. However, after secondary sulfurization and prolonged storage, it will gradually disappear! So having no odor is normal!

5. When choosing silicone products, we first look at the color. High quality colors are more vibrant, with a smooth surface that feels good when touched by friends; Poor quality silicone products feel rough to the touch and have a cloudy color.

6. Smell the odor. When smelling silicone products, there may be a slight odor due to residual sulfurizing agents, but this is normal. Generally, after being left in the air for a few days, the odor will be completely eliminated; Poor quality silicone products have a foul odor and a pungent smell.

7. In terms of usage, good silicone products are not easily deformed or twisted when pulled, have elasticity, and have bright colors:; Poor quality silicone products are prone to fading, deformation, and insufficient explosion resistance, making them easy to age.

8. Wear resistance is the ability of silicone products to withstand wear and tear during production and molding. Good silicone products generally have a surface that is rarely rubbed off by external factors, and does not affect the appearance, appearance, or color of the product. And the surface characters of low-quality silicone products are prone to falling off.

9. Elasticity, silicone products have good elasticity because high elasticity mainly comes from the movement of silicone molecular segments. Therefore, when purchasing silicone products, first check the elasticity of the silicone product to determine its quality.

10. Fatigue resistance: The phenomenon in which the structure and properties of silicone products change when subjected to alternating stress (or strain) is called fatigue. The phenomenon of damage to silicone products during the fatigue process is called fatigue failure. So fatigue resistance is also a method of identifying the quality of silicone products.

11. Hardness and tensile stress are important indicators of the rigidity (stiffness) of silicone materials, which are the forces required for silicone products to undergo certain deformations. It is also a method of identifying the quality of silicone products.

12. In terms of characteristic and tactile feel, silicone products have good toughness and elasticity, and are not easily deformed by external forces. Moreover, the tactile feel is relatively smooth, while counterfeit silicone products are prone to deformation and feel rough.

13. In terms of characteristics, silicone products are non-toxic, odorless, colorless, with good texture and no harm to the human body. However, it is difficult for counterfeit silicone products to achieve these effects. Counterfeit silicone products are generally toxic, have a pungent odor, and are also relatively rough!

14. At the same time, it is also very useful to judge the authenticity of silicone products through the convenience of flame combustion. Counterfeit silicone products have excellent smoke residue as black powder when burned, while real silicone products emit white smoke and white powder residue no matter what color they are burned.
