quality Silicone Rubber Keypads & Conductive Rubber Keypads manufacturer

In the rubber industry, with the development of production and the improvement of the performance of rubber products, the problem of increasing heat generation in the process of rubber processing has appeared. Therefore, how to ensure the safety in the process of processing has become an important topic. Now the main method is to add a small amount of anti-coke agent in the process to improve the safety of the processing process, increase the storage life of the rubber or glue, when adjusting the vulcanization system is difficult to achieve the required operation safety, adding anti-coke agent can often easily meet the requirements of the scorch performance of the rubber. In the process of storage and processing, due to the effect of heat, early vulcanization (cross-linking) will occur and lose the fluidity and reprocessing ability, which is the scorch phenomenon. The burning of rubber is one of the common problems in the process of rubber processing. The burning problem is more likely to occur in the modern characteristics of high temperature, fast and efficient processing technology and the mixing agent that is easy to cause burning (such as reinforcing resin, intermethyl white system adhesive, fine particle carbon black, etc.). Coke burning can be solved by adjusting the vulcanization system, but be careful to change the properties of the compound; The storage or processing conditions of the adhesive can be improved by cooling, but complex equipment is needed, and the use of anti-coke agent is a simple and easy way to prevent scorch. Therefore, the anti-coke agent has become an important operating assistant for the safety of rubber processing.

Basic testing standards for silicone products   1. Material safety testing First of all, the material safety of silicone products is the primary consideration. This includes harmful substances such as heavy metals in silica gel raw materials (lead, mercury, cadmium, etc.), harmful additives (such as plasticizers), volatile organic compounds (VOCs), etc. These tests are usually carried out in accordance with relevant international or domestic safety standards, such as the European Union's ROHS directive and REACH regulations As well as China's GB/T standards, etc., to ensure that the product is harmless to the human body and meets environmental protection requirements.   2. Physical performance test Physical property test is an important step to evaluate the basic properties of silicone products. This includes, but is not limited to, hardness testing (e.g. Shaw Hardness), tensile strength, tear strength, resilience, wear resistance, aging resistance, etc. These tests are intuitive The durability and service life of silicone products ensure their stability and reliability in various application environments.   3. Weather resistance test The weather resistance test of silicone products is also essential. This includes high temperature resistance, low temperature resistance, ultraviolet resistance, ozone resistance and so on Tests to simulate the use of products in extreme environments to assess their performance changes and degree of aging. Especially for Outdoor use of silicone products, such as seals, gaskets, etc., weather resistance testing is particularly important.   Inspection standards for specific application areas   1. Silicone products for medical devices For medical device silicone products, in addition to the above basic testing, biocompatibility testing is also required. This includes cells Toxicity test, sensitization test, intradermal irritation test, etc., to ensure that the product will not cause adverse reactions when in contact with the human body Yes. At the same time, it also needs to meet the relevant regulations and standards for medical device registration, such as ISO 10993 series standards.   2. Food grade silicone products The testing standards of food-grade silicone products are more stringent, and it is necessary to ensure that the product will not release harmful substances when in direct contact with food Quality. This includes the purity requirements of the silica gel raw material, the testing of migratory substances (such as heavy metals, plasticizers, etc.), smell and taste Dao test, etc. At the same time, it also needs to meet the regulatory requirements of various countries on food contact materials, such as the US FDA and the EU LFGB Let's wait.   3. Electronic and electrical silicone products Electronic and electrical silicone products need to be tested for electrical performance because of the particularity of their application environment. This includes insulation resistance Voltage resistance testing, flame retardant testing, etc., to ensure that the product will not cause electrical safety problems during use. In addition For some silicone products for specific purposes, such as conductive silicone buttons, electrical conductivity testing is also required.

In modern industry and daily life, the application of electricity is everywhere, and the accompanying electrical safety problems are increasingly attracting people's attention. Silicone products have a wide range of applications today, silicone gloves as a common protective equipment, its insulation and anti-electrical properties play an important role in ensuring the safety of personnel.   1. Insulation performance of silicone gloves Silicone gloves are protective gloves made of silicone material with good elasticity and wear resistance. More importantly, the silicone material itself has a high resistivity, which makes the silicone gloves have excellent insulation properties. When the human body comes into contact with the charged body, the silicone gloves can effectively block the current path and reduce the damage of the current to the human body. Therefore, silicone gloves are widely used in electric power, electronics, chemical and other industries need to contact live bodies.   2. Electric resistance of silicone gloves The electric resistance of silicone gloves is not only related to its material characteristics, but also closely related to its production process, thickness, use method and other factors. Generally speaking, the higher the insulation resistance of silicone gloves, the better their electrical resistance. At the same time, the thickness of the gloves is also an important consideration, and thicker gloves usually have better insulation. However, over-thick gloves can affect hand flexibility, so insulation and comfort need to be weighed in practical applications.   3. Application of silicone gloves Silicone gloves are widely used in the following situations because of their excellent insulation and anti-electrical properties: Power industry: When conducting power equipment maintenance, maintenance and other operations, silicone gloves can effectively protect staff from electric shock damage. Electronic industry: In the process of production and maintenance of electronic products, silicone gloves can prevent electrostatic damage to sensitive components. Chemical industry: When handling certain chemicals, silicone gloves can effectively isolate chemical substances from skin contact, reducing the risk of chemical burns.
