In the silicone products industry, the hardness of the product determines its functional role and appearance texture, while the silicone material is also divided into a variety of different hardness, for different product applications to choose different degrees of softness, such as silicone protective cover The use of 40 to 60 degrees, is moderate hard and soft, is also a relatively common hardness range, and the hardness of the silica gel determines the appearance quality of the product and the quality of the processing, and the advantages of low hardness silicone materials and What are the drawbacks?
Low-hardness silica gel materials are usually used in softer, softer cushioning products. They are more common in daily necessities. They can achieve good texture when in contact with skin. For example, silicone cleansing instrument skin care tools, the advantages of this type of product. It can achieve good results and the life of the product can be better, the texture is better, and the product has better compressive cushioning resistance, the product is not easily deformed after long-term stress, and the rebound efficiency after long-term stretching. fast.
In addition to the advantages of consumer use, low-hardness silicone rubber products will also have corresponding drawbacks in the production process. For example, some products are prone to edge breakage and bursting when produced by silicone products manufacturers. The main reason is due to the hardness of silicone materials. Too low, the fluidity of the product is relatively soft, the speed of placing the rubber can not keep up with the temperature of the mold, and the material has gradually solidified when the mold is clamped up and down. The edge is difficult to be combined and damaged, and the softness of the silicone material is too soft. The greater the phenomenon, such as the failure to strictly control the time of vulcanization and the time of entering and leaving the mold, it is likely to cause soft deformation of the product.
For consumers, the low-hardness silicone products are more difficult than the surface-treated products. Adsorption of dust has become the biggest drawback. Many friends who purchase softer silicone products should have this phenomenon. After long-term use, the surface will appear. The layer gradually darkens, and this is also a drawback of the lower hardness silicone products, but this phenomenon does not occur after antistatic treatment.
