The waterproof ring made of silica gel as raw material is called the silica gel waterproof ring, the silica gel waterproof ring is generally O type, is a classification of silica gel products, is made of silica gel ring items, generally in the need for waterproof and sealed place to use the silica gel waterproof ring. Then the following by our Lanxin Rubber and Plastic Co., Ltd. to tell you about the silicone waterproof ring!
First, raw materials. Let's start with the ingredients:
(1) General silica gel raw materials can be divided according to the performance, divided into ordinary silica gel and meteorological silica gel;
Ordinary silica gel: named precipitation silica gel, tensile rate can reach 400 percent, generally used for the production of silica gel miscellaneous, silica gel buttons, conductive silica gel, etc., generally used for the production of middle and low grade silica gel products.
Weather silica gel: named pure silica gel, transparent, its density is generally 1.1-1.2g /㎡, the stretching rate can reach 700 percent, because of its transparency and strong stretching ability, generally used to make silica gel tube. Protective cover and other products, but this silicone cost is higher.
② If according to the physical properties of silica gel raw material, it can be divided into liquid silica gel and solid silica gel;
Solid silica gel: generally made of molded molding process, used to make silica gel kitchenware, silica gel buttons, silica gel cover, etc.;
Liquid silica gel: generally made by extrusion process, used to make silica gel pacifier. Silicone tube, etc.
Two, silica gel waterproof ring is a good waterproof sealing material, because the silica gel waterproof ring is resistant to high and low temperature, sealing and insulation is good and environmental protection, the hardness of the general silica gel waterproof ring is 19-89 degrees.
Three, what are the characteristics of the silicone waterproof ring?
① Non-toxic and harmless;
(2) This material has strong plastic properties;
③ The ambient temperature ranges from -59 degrees to 199 degrees;
④ Its hardness is generally 29-69 degrees;
(5) with high pressure aging resistance, weather resistance;
Oil resistant, so oil resistant environment is not suitable for use, but in the climate resistant environment is commonly used, but the price is more expensive.
Four, silicone waterproof ring is often used in electronic equipment. O ring, washer, protective ring, waterproof sleeve, etc., can also be used for mechanical insulation, sealing.
The above is the whole content of this article, you now have a certain understanding of the silicone waterproof ring? Feel free to leave a comment below!
