Silicone in the construction sector

Silicone in the construction sector is essential, due to its versatility, durability and adaptability to the most avant-garde designs.

We can find this material in countless applications. They are located in the exteriors and interiors of buildings, such as interior design, lighting and decoration elements. Due to its characteristics of excellent behavior against heat, UV rays, abrasion, deformation, aging and permeability, it is guaranteed that the useful life is high, which helps to maintain the structural integrity of the building, while ensuring a good insulating behavior of pollution, dust, water, etc. It also has excellent results when absorbing tensions and vibration movements.

In Merefsa we can design any project, test and customize according to the needs of our customers:

Silicone strengths

Silicone strengths

Mechanical: Great resistance, due to its excellent deformation behavior, is ideal for sealing, maintenance of tightness and insulation against dust and other weather agents. It also has a good behavior to absorb vibrations and movement of structures. Fluoridated silicone is used in those applications that, in addition to working at high temperatures, need high resistance to corrosion.

Thermal: unbeatable response to temperatures -60 ° C to 300 ° C l makes it essential in situations of continuous exposure to the sun and extreme weather agents (Uv rays , etc.).

Chemical: Thanks to specific formulations of hardness, color, transparency, etc., it can be adapted to any construction design on facades as in interior design solutions.
