Among all aspects of performance, silica gel and TPU have their own advantages:
Hardness: TPE is harder than silica gel, but TPE softness is closer to the human body, and the hand feels softer (TPE is a new material coming out in recent years)
Aging resistance: TPE is more suitable for normal use under normal temperature than silica gel. Both materials can meet more than 10 years.
Wear resistance: TPE is better than silica gel. The silica gel is too soft, it is afraid of scraping. TPE is a high-density mixture, which is relatively scratch-resistant.
High temperature resistance: Silicone material is better than TPE material, silicone material can withstand temperature of 220 degrees, and TPE material can withstand temperature between 60-100 degrees.
Oil-resistant liquidity: Silicone has better oil resistance. It is also placed in ozone and oil environment. Silicone material is superior to TPE, so it can be selected as silicone seal, oil seal gasket, etc.
Stretch rebound: TPE material is more, its material can be stretched to more than 1000% with different hardness, and silica gel is about 300%-500%.
The cost is high and low: the silicone material is synthetic rubber, which is made up of various materials, and the production process is complicated. The silicone product manufacturers can choose various methods for production and processing, and different materials have different raw material cost prices. Therefore, the raw materials for the above are expensive but the processing cost is high.
TPE is a thermoplastic material, but it has a high amount of glue and can be recycled. Excellent processing performance, no need to vulcanize, can be recycled to reduce cost, can be double injection molding, coated with PP, PE, PC, PS, ABS and other base materials, or can be molded separately.
Therefore, in combination with the above comparison, both TPE and silicone rubber materials are easy to use, and TPE is an emerging material, which can help more in different fields. Silicone materials can always do many products, but they also do TPE or other materials just fill the gap.
