Introduction Of Natural Antistatic EVA Compound
- LC168A is a natural antistatic EVA compound formulated with EVA resin a certain amount of permanent antistatic agent, and other additives like ZNO, ZNST, and BIPB. This antistatic compound is designed for foaming molding. The surface resistance of the specimen after foaming is 10^7-10^9 Ohms/sq. It is mainly used to make slippers or soles. It can effectively eliminate the accumulation of natural charges and play a role in transmitting static electricity that may be generated when the human body contacts the ground.
- Natural antistatic EVA foam grade is a natural permanent antistatic compound, the main components of which are ethylene vinyl acetate and permanent antistatic agent. Traditional antistatic EVA uses carbon as a conductive filler. The biggest advantage of natural antistatic EVA foam grade is that the appearance is natural color, or can be colored.
- LC170A is a customized ESD compound that can be colored, has an expansion ratio of 1.25(125%), hardness of 60-65 C, long-lasting antistatic performance, oil resistance, and wear resistance. It is used to produce ESD EVA packaging materials, which play a role in buffering and protection.
Characteristics Of Natural Antistatic EVA Compound
- Colorable: Natural antistatic EVA foam grade has a long-lasting antistatic effect, and masterbatches can be added to create other colorful colors.
- Cushioning and shock absorption: In addition to the antistatic function, antistatic EVA foam also has excellent cushioning and shock absorption effects, which can protect the product from impact and vibration during transportation, storage, and use.
- Soft and comfortable: The soft texture and lightweight can provide better comfort, such as insoles, sports equipment, etc.
- Chemical corrosion resistance: Natural antistatic EVA foam grade has a good tolerance to certain chemicals and can maintain stable performance in different environments.
- Easy to process: It can be processed by cutting, stamping, hot pressing, and other methods to meet the needs of various shapes and sizes.
Applications Of Natural Antistatic EVA Compound
- Electronic and electrical industry: Natural antistatic EVA can be used as packaging materials for electronic products, such as the lining of packaging boxes for mobile phones, computers, cameras, etc., which play a role in shock absorption, anti-skid, and anti-static.It can also be used as packaging materials for electronic components, such as integrated circuit chips, resistors, and capacitors, to prevent static electricity from damaging sensitive electronic components.
- Precision instrument field: Natural antistatic EVA foam grade is used to make trays, packaging boxes, and other packaging materials for precision instruments. For example, the transportation packaging of large precision instruments such as electron microscopes and mass spectrometers can prevent vibration and collision during transportation from damaging the instruments, and also avoid the impact of static electricity on the instruments. It is also used for pads and table mats for laboratory equipment to provide a safe working environment.
- Medical industry: Adding natural antistatic EVA compounds to medical protective clothing, gloves, masks, and other protective equipment can reduce static electricity, prevent the adsorption of harmful substances such as viruses and bacteria, reduce the risk of infection, and avoid static electricity from interfering with medical equipment. Some medical equipment accessories, such as electronic blood pressure monitor cuffs and blood glucose meter test strip storage boxes, use antistatic EVA to avoid the use effect and measurement accuracy affected by static electricity adsorption of dust.
Is Natural Antistatic EVA Permanent Antistatic?
Natural antistatic EVA can achieve long-term antistatic performance for the following reasons:
- From the perspective of an antistatic agent: EVA with a permanent antistatic agent added because the permanent antistatic agent itself is a polymer substance and has a certain compatibility with the EVA matrix resin. After blending, it can build a mesh conductive channel inside and on the surface of EVA, conduct and release the generated static charge through ion conduction, and continue to play an antistatic role during the use cycle of EVA.
- From the perspective of material structure: Natural antistatic EVA is a polymer crystalline polymer elastomer with an alternating cycle structure of polar segments and amphiphilic segments. It has good compatibility with EVA. After being added to EVA, it can be highly dispersed in EVA without exudate affected by the external environment (temperature/humidity and wear). It continues to be antistatic during the service life of the material.
- From the perspective of actual effects: In actual applications, when high molecular antistatic agents and other ingredients are added in appropriate proportions to produce natural antistatic EVA, its surface resistance can reach a low level and be maintained for a long time, which can effectively prevent the generation and accumulation of static electricity and maintain antistatic properties for a long time.
