Difference between silicone seal ring and TPE seal ring

Jan. 26, 2021

The performance of silicone sealing ring is as follows:

1.   The tensile strength can reach 1500 PSI and tear resistance can reach 88 LBS, with good elasticity and good compression ratio.

2.   It has good resistance to neutral solvent.

3.   Excellent heat resistance. Silicone rubber has much better heat resistance than ordinary rubber, can be used almost forever at 150 without performance change, can be used continuously at 200 for 10000 hours, and can be used for a period of time at 350. Widely used in heat-resistant occasions, thermos sealing ring, pressure cooker ring heat-resistant handle.

4.   Excellent cold resistance. The ordinary rubber is -20-30, that is, silicone rubber still has good elasticity at -60-70. Some special formulations of silicone rubber can also withstand very low temperature, can be heated at high and strong temperature, do not deform, and do not produce harmful substances. For example: low temperature sealing ring.

5.   Excellent resistance to ozone and oxide erosion.

6.   Corona resistance, arc resistance, high and low temperature resistance, good aging resistance, high temperature resistance, meet the FDA and SGS standards.

7.   Excellent electrical insulation, long-term use of no yellow and no fading.

TPE (Thermoplastic Elastic) is a thermoplastic elastomer material with the characteristics of high strength, high resilience, injection molding, wide application, environmental protection, non-toxic and safe, and excellent coloring. TPE sealing ring products can be divided into oil resistance and non-oil resistance, oil resistance toluene, gasoline, oil, alcohol and so on, the product elasticity is good compression resistance permanent deformation, and can be bonded with PP.

1.   TPE plastic processing advantages include: injection molding, extrusion, blow molding, easy processing, hot welding, small tolerance, high precision, rich color.

2.   TPE materials have excellent elasticity, oil resistance, weather resistance, aging resistance, flexural resistance, ozone resistance and chemical properties.

3.   Waste can be recycled 100%, greatly reducing the processing cost of products, has become the latest material to replace traditional rubber, but also the latest environmental protection materials.

4.   Compared with rubber processing, it saves mixing, mixing and vulcanization, and reduces energy consumption, labor consumption and environmental damage.
