A question often asked in the industry: TPE or Silicone rubber? We will have to settle with: both materials have their strong sides. Thermoplastic elastomers, especially TPV, are well suited to endure more mechanical pressure and return to their original shape. Meanwhile, silicone rubber can take more heat! It has very specific applications as TPEs can temporarily reach above 90 degrees Celsius while silicone can be kept at 200 degrees Celsius without affecting sealing function. Of course, the production method varies, and so does the cost. Silicone is mixed at a cooled temperature, then heated to solidify and requires specific equipment, while TPE is heated to melt and cooled to solidify. The process takes less time, and the machines can be used for the various tonnage and hard plastic materials. You now understand the difference and why TPV is a material with a lower production cost.
