Silicone resin: encapsulation and protection solutions

Silicone resin is a benchmark technical solution for industrial applications requiring high temperature resistance, durable flexibility and optimal component protection. It is particularly used in demanding environments where thermal, electrical, and mechanical constraints are high.

Thanks to its stability and ability to absorb stress, it helps to guarantee the reliability, safety and life span of electronic and electrical systems.

At ADDEV Materials, we support manufacturers in the Bespoke selection and packaging of silicone resins, in order to optimise their performance and integration into processes.

Silicone resin vs. other resins: What's the difference?

Silicone resin is positioned as a high-performance solution for extreme environments.

Silicone resin vs. epoxy

silicone → high thermal resistance, flexibility
Epoxy resins are a class of thermosetting polymers that are widely used in various applications due to their excellent mechanical properties, chemical resistance, and adhesive qualities. Here's a breakdown of "rigidité" and "résistance mécanique" in the context of epoxy: **Rigidité (Rigidity)** In the context of epoxy, rigidity refers to its stiffness and resistance to deformation under stress. A rigid material will maintain its shape and not bend or flex significantly when a force is applied. * **Young's Modulus:** This is the quantitative measure of a material's rigidity in the elastic deformation range. A higher Young's modulus indicates greater rigidity. Epoxy resins typically have a high Young's modulus, contributing to their use in structural applications. * **Dimensional Stability:** Rigid materials tend to have good dimensional stability, meaning they don't change shape or size easily with temperature fluctuations or under load. This is crucial for applications where precise dimensions are required. **Résistance Mécanique (Mechanical Strength)** Mechanical strength is a broader term that encompasses several aspects of how a material behaves under various types of stress. For epoxy, this includes: * **Tensile Strength:** The maximum stress a material can withstand before breaking when stretched or pulled. Epoxy resins generally exhibit good tensile strength. * **Compressive Strength:** The maximum stress a material can withstand before failing under compression. Epoxies are known for their high compressive strength. * **Flexural Strength:** The ability of a material to resist bending. While rigid, some epoxies can also have good flexural strength, allowing them to withstand bending forces without fracturing. * **Impact Strength:** The ability of a material to absorb energy and resist fracture when subjected to a sudden blow or impact. The impact strength of epoxy can vary significantly depending on the specific formulation, curing agent, and any additives used. * **Fatigue Strength:** The ability of a material to withstand repeated cycles of stress over time without failure. **In Summary for Epoxy:** When we say epoxy has "rigidité, résistance mécanique," we mean it is: * **Stiff and Doesn't Deform Easily:** It maintains its shape under load. * **Strong:** It can withstand significant forces applied in tension, compression, and bending before failing. * **Durable:** These properties make it suitable for demanding applications where structural integrity and long-term performance are essential. The specific values for rigidity and mechanical strength will vary greatly depending on the exact epoxy resin system (e.g., bisphenol A-based, epoxy novolacs) and the curing agent used, as well as processing conditions and post-curing treatments.
