Imitation of silica gel TPE material TPE to replace silica gel raw material
There are many types of new environmental protection materials and high similarities. Currently, organosilicon products are difficult to distinguish, such as TPE materials, TPR materials, PVC materials, TPU and TPE materials. On the surface, many of them are identical in terms of bones, but in fact they have some differences in performance and longevity. For example, the current TPE material is one of them. In practice, what is the difference between it and silicone products?
When it comes to TPE materials, it is one of the most popular new materials in recent years. It is a highly elastic(or even better), high-strength, high-elastic, high-wear resistant thermoplastic elastomer material, and is used in conjunction with silicone rubber products. It also has environmentally friendly, non-toxic human skin contact. On the contrary, it can also be used for medical treatment and necessities of life. Many materials can be replaced. Silicone products.
In all aspects of performance, silica gel has the following advantages:
1. Hardness and softness: TPE is harder than silicone, but TPE is softer and softer than the human body. (TPE is a new material developed in recent years)
2. Aging resistance: When TPE is larger than silicone, TPE is more than 6-8 years old, and the two materials can be used normally at room temperature.
3. Abrasion resistance: TPE is superior to silicone, mainly because the silicone is too soft to scratch. TPE is a high-density mixture that is relatively scratch resistant.
4. High temperature resistance: Silicone material is better than TPE material, silicone material can withstand high temperature 220 °C, TPE material can withstand high temperature 60 ~ 100 °C.
5. Oil resistance: Silicone has good oil resistance. Silicone gel material in ozone and oil environment, its performance is better than TPE, can be used as silicone rubber sealing ring, oil sealing gasket.
6. Reentry: There are more TPE materials, TPE materials with different hardness can be extended to more than 1,000 %, and the stretch of silica gel is about 300-500 %.
Cost: Silicone materials are rubber, made of a variety of materials, and the production process is complex. Silicone manufacturers can choose a variety of methods of production and processing, and different raw materials have different raw material cost prices. Therefore, the raw material price of the above raw materials is higher, but the processing cost is higher.
Thermoplastic elastomer is a kind of thermoplastic material, but its adhesive content is very high and can be recycled. The method has the advantages of good processing performance, no need for vulcanization, recyclable use, and reduced cost. It can be used for secondary injection molding, and can be coated and bonded with PP, PE, PC, PS, ABS, PA, etc.. And can be formed separately.
Will silicone be replaced by TPE materials? Do you really know about thermoplastic TPE?
Therefore, compared with the above materials, thermoplastic elastomers and silicone are materials that are easily available to us, while thermoplastic elastomers are new materials that are more helpful in different fields. Silicone materials can already make many products, but there are also some areas and products that can not be done, and TPE or other materials just fill this gap.
