Engineers in the rubber and plastics industry all know that TPE and silicone are very similar in both materials, and the use environments and roles of both silicone products and TPE products are similar. In some mechanical and electronic accessories, the waterproof sealing effect is Children’s gift toys, etc. can be used in these two materials, and now the two materials are more widely used in which one is more biased towards you, but what remains to be seen is who will soon have the advantage and advantage in the modern technology era?
It is necessary to know that the silicone material originated in the 18th century, and the thermoplastic TPE was born in the middle of the 19th century. It began commercialization at the end of the 19th century and gradually developed thermoplastic plastics used as some hard plastic products. However, from a historical point of view, the development time is still far. Far behind the silicone material, and from the technical point of view today’s TPE material has gradually improved in the past decade, from 1972 began to study the use of soft thermoplastic elastomer to soft TPE used for nearly 50 years, obtained today widely used!
The difference between silicone products and TEP products:
Silicone rubber products:
1. Environment-friendly silicone can be used as a medical grade to contact the interior of the human body
2. Good resistance to environmental and solvent properties
3, good pull back elasticity, no deformation, no fading
4, high and low temperature resistance, aging resistance, good corona resistance
5, good heat insulation, high density, wide range of use
6, the original material deployment, silicone products manufacturers need to carry out the mixing process to dissolve the raw materials into the vulcanizing agent in the add color paste to cut
TPE products:
1, has good elasticity, weather resistance, aging and oil and ozone resistance
2, single processing, injection molding, extrusion, blow molding, forming, trimming
3, heat welding, small tolerances, high precision, high efficiency, rich colors
4, soft material, strong rebound, good fatigue resistance, good aging performance
5, simple and superior processing performance, no vulcanization, can be reused
To sum up, TPE and silicone material have no better and the best, but still need to prescribe the right medicine, spotting the use of the product to prove that silicone rubber products can be called with environmental protection materials, but as mechanical seals, oil seals and construction engineering industry accessories accessories Such as can still choose TPE, but must choose the environmental protection is strong, the resistance high temperature is good, pulls up the springback strength to be good or selects the silicone rubber material to be better, the different environment and the function selects the different material.
