< p > silicone products depending on the molding process, can be divided into several classes? < / p > < p > the silicone products are environmental protection, no pollution. Whether the refining of raw materials or finished products processing will not cause pollution and damage to surrounding environment. And the use of silica gel products temperature range is wide, especially for high and low temperature tolerance of other materials you never even. Minimum to minus 40 degrees highest can resist the high temperature of 230 degrees. In the pressure cooker and microwave oven can be safe and sound. < / p > < p > therefore, silica gel products depending on the molding process, can be divided into the following four categories: < / p > < p > < / p > < p > 1, liquid silica gel. < / p > < p > by silicone injection molding injection molding liquid silicone products, products, soft hardness can reach 10 ° C - 40 ° C, because of its soft features of simulation in human organs, medical silicone breast implants, such as widely used. < / p > < p > 2, silicone extrusion. < / p > < p > extrude silicone products usually by extrusion of silicone extrusion molding machine, extrusion silicone strip shape commonly, tube can be cut at random, but the shape of the extruding silicone have limitations, in medical apparatus and instruments, widely used in food machinery. < / p > < p > 3, molded silicone. < / p > < p > usually through high temperature mold mold silicone articles after the solid silica gel is put in the add curing agent raw materials through vulcanization machine pressure, high temperature sulfur solidification molding, molded silicone hardness at 30 ° C - usually 70°C。 Raw material with color paste according to the pantone number to bring up the color, the shape of the die determines the shape of the molded silicone products, molded silicone products is one of the most widely employed in the silicone industry. < / p > < p > 4, special products. < / p > < p > special silicone products are according to the chemical properties of the silicone or add some auxiliary materials, special silicone products can also be with high temperature resistant, Up to 330 degrees c) , food grade, Full compliance with FDA, LFGB standard) Levels, medical, flame retardant, by adding auxiliary raw material can also have, luminous, negative ions, discoloration, etc. < / p > < p > more exquisite silicone products, such as mobile phone silica gel set in zhe embellish too silicagelzrt. com


have manifold silicone cover effects, ranging from earbud accessories to earbud accessories.
During Dongguan ZheRunTai silicon Technology Co., Ltd’s existence in a market we didn’t receive any negative feedback from our customers.
These earbud accessories silicone cover are not only useful but also more cost effective than those traditional ones.
