These are elements that form part of high performance fastening systems for railways. The main purpose is to provide a high level of attenuation to the noise and vibrations caused by trains passing over the rails, and which are transmitted to the buildings near the railway installations.
Due to the way these pieces work and the need to achieve a high level of elasticity that lasts over time, the most commonly used raw material is natural rubber, to which agents are added that reinforce its behaviour in the face of environmental aggression (climatic shocks, UV rays, etc.) that are characteristic of the places where it is installed.
To ensure the good quality of the products installed on the railway networks, there are a number of European standards, which indicate the demanding tests that these must pass.
The pieces injected by Junta3 comply perfectly with the European standards applied to this type of product.
