Many people do not understand the difference between silica gel and TPU, because TPU is also soft, and silica gel belongs to soft rubber products, and even some Taobao sellers do not know, the soft are said to be silica gel. TPU belongs to the plastic category, the product is made by injection molding process, which is to melt the plastic rice grain by grain, and then shoot the gun into the plastic mold to make the product. Silica gel belongs to rubber, molding process is vulcanized molding.

 

Silica gel mold is open up and down mold, cut a piece of silicone raw material, put it in the mold, heating and pressure to make products. General plastic products will have a glue mouth, in the product after injection to trim, trim is not good very affect the appearance. The silica gel has no glue inlet, but there is a ring of rough edges around it to repair. If the mold is not good, the ring of rough edges will be more obvious.

 

From the feel, the hardness of the general TPU will be harder than the silica gel, the elasticity of the hand pinch is strong, the elasticity of the silica gel is slightly worse. TPU can be compared to the feel of muscle, silicone is compared to the feel of fat. TPU products are more high-grade, pattern changes are more than silica gel, can be more selective, from the outside, TPU can do the kind of very transparent, silica gel can not, the most transparent are very hazy like the thick fog that feeling, it is because of this transparent feeling of TPU, more popular with users.
