A Comprehensive Guide to Understanding the Properties of Silicone Rubber

图片
  Silicone rubber is widely used in various industries due to its unique properties. It is a synthetic elastomer with a wide range of applications, including sealing, insulation, and vibration dampening. Understanding the properties of silicone rubber is crucial for selecting the appropriate material for specific applications. In this article, we will provide a comprehensive guide to understanding the properties of silicone rubber. Temperature Resistance: Silicone rubber exhibits excellent temperature resistance and is capable of enduring temperatures up to 250°C. It retains its flexibility even at extremely low temperatures, making it ideal for use in harsh environments. Chemical Resistance: Silicone rubber is resistant to a wide range of chemicals, such as acids, alkalis, and solvents. It also resists degradation from exposure to water, oils, and UV light. Electrical Insulation: Silicone rubber is an excellent electrical insulator due to its high dielectric strength, lo...

Liquid Silicone Rubber (LSR) Will Get Wider Application In Medical Industry

   With the continuous progress of science and technology, all fields of society are developing, among which the development of the medical industry is changing with each passing day, and many medical problems are constantly being overcome. Although the development of medicine depends on medical talents, "the work is good, must first improve its tools" Good medical skills also need some medical equipment and medical materials to assist, silicone is now an important material in the medical field.   In modern medicine, medical silicone rubber has been widely used either in medical equipment or implanted into the human body. This also benefits from the stable physical properties of silica gel: non-toxic, physiological inertia, resistance to biological aging, small reaction to human tissue, good biocompatibility, and no harm to the human body. But not all silicone can be used in medicine and the human body, in the matter of human health, everything has strict standards. Ther...

What is Liquid Injection Moulding?

  I. What is liquid silicone rubber molding? Liquid silicone rubber (LSR) molding, sometimes called liquid injection molding (LIM), is a thermosetting process in which two compounds are mixed and then heat-cured using a platinum catalyst inside a mold to create flexible silicone parts. Low compression permanent deformation and the ability to resist extreme temperatures make LSR molded pieces durable and ideal for challenging applications. LSR elastomers offer superior optical clarity, durability, and design flexibility while operating over a wide temperature range (-50℃ to 250℃). LSR injection molding is suitable for manufacturing complex geometric shapes, and because of its design and mold flexibility, multiple functional components can be combined into a single part. LIM has considerable advantages in terms of product reliability and total tooling cost. II.How is LSR different from injection molding? LSR molding is very similar to the way traditional injection molded parts are ...

The Reasons For Affecting the Precision of Silicone Seals

 The reason for affecting the precision of silicone seals ? For products with high precision requirements, it is necessary to function within the range of its tolerance. In the silicone rubber industry, the precision tolerance requirements of products are not very strict. There are often some special silicone rubber electronic parts, silicone rubber precision accessories, and other products that need high precision requirements. So there are some difficulties in the custom processing of silicone rubber products that want to achieve high precision. The primary reason is the horizontal calibration of the machine. The precision silicone manufacturing machines. The size of the silicone products is better, and the deviation of the larger product size is 0.3-0.5mm or so, which is a common phenomenon. The problem of the machine mainly stems from whether the upper and lower bearings are symmetric, whether the template is symmetric and whether the ground is symmetric and other factors! The ...

What is The Difference Between Silicone Overmolding and Doubt-shot Molding?

图片
   Silicone overmolding and doubt shot molding are two silicone molding technologies widely applied in custom silicone products & parts. The two silicone molding technologies are complex and difficult to operate and grasp because they need to obey strict tolerance. Silicone overmolding is done with a normal injection molding machine, and then take out the first forming products, and add another injection molding machine. The Double Shot Molding is completed by a Double color injection Molding machine, a molding that can have two kinds of color effects and different materials. Here, we will discuss double-shot molding and the difference between the two silicone molding and their advantages.   I. Silicone Overmolding   Silicone overmolding is the silicone rubber material forming sheet, and plastic parts, such as tubing and plate shape. In general, the substrate material (the first block to bonding with other materials) is into the injection mold, then coating form...

How To Choose High-quality Silicone Foam Tubing?

  With the more prosperous silicone products industry, the silicone products industry has become a more widely used product, such as industrial fields, daily necessities, medical, recreational, and sports activities, because of the rapid development of the silicone rubber products industry, the market demand for silicone rubber products is also increasing. Among the many silicone products, many silicone products are popular and widely used. Among them, silicone foam tubing is a more common one. Silicone foam tubing is made by extrusion process. So it creates a lot of little holes in it. General silicone foam tubing is used for sealing operations. It also has a nickname for "silicone sponge tubing". Silicone foam tubing not only has high and low-temperature resistance but also has good insulation, aging resistance, and ozone resistance. General silicone foam tubing is used in construction, car, ship Windows and other sealing, cable wire and other parts, and some industrial pro...
