Silicone LSR

Silicone is an inorganic polymer synthesized in 1907 by Frederick Kipping, based on a silicon-oxygen chain and organic groups linked to the silicon atoms. In the market you can find different types of silicone, with different characteristics and structures, some more gummy others more oily, and can be divided into areas of application, such as liquids, emulsions, compounds, lubricants, elastomers, plastics, etc. To obtain rubber objects of defined shape, it is possible to vulcanize silicone rubbers at both high temperatures and ambient temperatures. Silicone rubbers are polymer masses which can be vulcanized with the addition of a suitable catalyst or curing agent. They are classified as HTV (High Temperature Vulcanizing) if they vulcanize at high temperatures and RTV (Room Temperature Vulcanizing) if they vulcanize at low temperatures.

The rubbers known as LSR (Liquid Silicone Rubber) are liquid rubbers that are injected into moulds which, at the time of transformation, are mixed using two components. The time for the vulcanization varies depending on the type of catalyst or curing agent. This type of rubber has numerous advantages in the processing stage, among which we can mention:

  • Easy colouring
  • Odourless and tasteless
  • Transparency
  • Resistance to laceration at 25-50 kN/m
  • Working temperatures from -60 ° C to 250 ° C
  • And many others
