Benefits of Liquid Silicone Rubber From a Musensil Raw Material Manufacturer

There is a wide range of different types and grades of liquid silicone rubber (LSR) to suit many different applications.musensil lsr raw material manufacturer They have a variety of elastic properties, can be soft and tacky or have a harder, more solid feel. They can also have a wet or oily surface. There are LSRs that are specially formulated to withstand high temperatures, as well as those that have a self-lubricating effect when used in oily environments. There are also conductive-grade versions that can be used in electrical contacts and cables.

One important difference between LSRs and thermoplastics is that the raw material must be injected into a mold to become a finished product.musensil lsr raw material manufacturer This is accomplished by a process known as injection molding. The injection process can be manual or automated. In most cases, the two components of the LSR, referred to as Part A and Part B, are mixed together in a static mixer, then pumped into the injection machine at a 1:1 ratio. The injection machine is then heated to a specific temperature to initiate the curing reaction.

A key advantage of this technology is that the cured silicone will stay clamped together once it has been injected into a mold.musensil lsr raw material manufacturer This reduces cycle times considerably compared to high-consistency gum based and organic materials. Injection molded LSRs typically cure in less than 30 seconds, while high-consistency gum based products require six or more minutes. Another benefit of LSRs is that they can be bonded directly to various thermoplastic substrates without the need for priming. This is known as 2C or simultaneous injection of technical plastics with LSR.

Another key benefit of LSRs is that they can withstand sterilization processes that are normally used in the manufacture of medical devices, personal care items and baby toys. This ability, combined with the flexibility of the material, allows manufacturers to create watertight barriers for showerheads and faucets, vibration resistant sealed housings for electric shavers and toothbrushes, and soft pliable surfaces for baby bottle caps and soothers.

In addition to the physical benefits of LSR, it is easy to work with due to its low viscosity. This makes it possible for small parts to be molded with complex shapes. This is particularly useful for companies that need to create custom molded parts for unique application requirements. The quality of the molded parts is dependent upon a number of factors including the type and grade of the raw material, the injection equipment, and the mold. Early quality planning and visual inspections will help to ensure that the resulting parts meet the required quality standards. ISO certifications such as ISO 13485 for the medical industry and IATF 16949 for automotive manufacturers provide further assurance that an LSR supplier has the quality systems and commitment to quality needed to deliver consistent, reliable parts.
