silicone liquido

Teknofluor Srl is a reference in the production of industrial rubber and plastic gaskets, with a particular focus on high quality materials such as liquid silicone (LSR). For more than three decades, the company has been distinguished by its constant commitment to research and development of innovative technical solutions, processing various materials and meeting the needs of the most demanding sectors.

Application fields

Teknofluor Srl’s range of LSR gaskets includes a wide range of red liquid silicone or transparent liquid silicone o-rings, lanyards and even design items. It targets a number of industrial sectors, including:

  • Automotive: seals for advanced systems, resistant to extreme temperatures and wear.
  • Medical: solutions meeting the highest standards for safe contact with the human body.
  • Food: materials certified FDA, BGA, KTW and MOCA for use in contact with food, guaranteeing safety and hygiene.
  • Electronics and electrical engineering: seals with excellent dielectric properties and resistance to external agents.
  • Ecology: components that meet the criteria of sustainability and durability.

Characteristics of Liquid Silicone 

This material, obtained by combining two liquid components, is transformed through injection molding into elastic precision articles, that is the gaskets of Teknofluor Srl. Its chemical and physical properties, such as the ability to withstand temperatures from -60 °C to +250 °C and its stability over time, make it perfect for applications in critical environments.

Liquid silicone gaskets offer a number of advantages that make them irreplaceable in many industrial applications:

  • Thermal resistance: excellent stability at high and very low temperatures.
  • Flexibility and durability: maintain elasticity and performance even after years of use.
  • Chemical stability: high resistance to ozone, UV rays and aging.
  • Food and medical compatibility: compliance with major international certifications including FDA, BGA, KTW and MOCA
  • Colour customization: possibility to obtain items in a wide range of colours, thanks to the use of specific colouring pastes.

Teknofluor Srl is able to develop special variants of LSR silicone for particular needs, such as:

  • Resistance to oils and fuels.
  • Flame retardant properties.
  • Electrical conductivity for specific technical uses.

Standard duretings and colours

The liquid silicone gaskets produced by Teknofluor Srl can be made in a wide range of hardness ranging from 20 to 80 Shore A. We have a large stock of LSR o-rings, with standard ropes 1.78, 2.62, 3.53, 5.34, 7.00 mm brick red or transparent, but we can also handle different sizes and colors depending on the customer’s choice.
