Duroplast – the material
Why DUROPLAST?
DUROPLAST, or more precisely duromers, are plastics that cure in three dimensions and can no longer be deformed after curing. This makes thermoset components suitable for replacing metal components. DUROPLASTICS are therefore genuine lightweight construction materials and can be used in a wide range of applications.
High dimensional stability, dimensional stability and thermal resilience are just some of its strengths. Even under challenging operating conditions, such as high service temperatures, DUROPLASTS retains their electrical and dielectric properties as well as its resistance to chemicals and organic solvents.
In addition, DUROPLAST offers very high design freedom for technical and optical components and, in its target design, permanent dimensional stability.
With properties such as high dimensional stability thanks to low coefficients of thermal expansion, advantageous fire behavior, high tracking resistance, abrasion resistance and self-extinguishing behavior, DUROPLAST is ultimately completely convincing.
We offer you innovative complete solutions in component production, from thermoset-compatible design to the production of prototypes and large series. We are a global supplier of DUROPLAST molded parts for the automotive, electrical and other industries. We see ourselves as DUROPLAST experts and therefore as a professional customer partner.
After processing and curing, thermoset materials develop their full range of profitable, individual and specifically desired properties. The preliminary products are usually synthetic resins mixed with fillers and colorants, while the end products are no longer deformable in their target design, as they contain hard, firmly bonded polymers that are three-dimensionally cross-linked. DUROPLAST components are characterized by extreme dimensional stability and resistance as well as high compressive strength due to their close-meshed cross-linking. Nevertheless, they can be individually adapted to your requirements using fillers, so-called additives such as glass beads, glass fibres, etc.
DUROPLASTS are no longer deformable after curing by heating or other measures. They contain hard, amorphous, insoluble polymers and are tightly cross-linked. The precursors are usually synthetic resins mixed with fillers and colorants. DUROPLAST components are extremely hard and dimensionally stable due to their close-meshed cross-linking. They also have a high compressive strength. The high thermal load-bearing capacity of DUROPLASTEN, which is enhanced by the addition of glass beads or glass fibers, among other things, can be significantly increased by the addition of inorganic fillers. In this way, thermoset components achieve a dimensional stability that can withstand a thermal load of several hundred degrees Celsius over many minutes.
After processing and cross-linking reaction, thermoset components have excellent media resistance. These include most fluids in the automotive environment, but also many alkaline solutions and other aggressive media. In particular, thermoset overmoulding/coating can effectively protect sensitive elements, such as electronics or sensors, from negative environmental influences.
The chemical structure and the fillers and ingredients used give thermoset components excellent electrical insulation properties. It is well known that thermoset materials are used in both domestic and high-voltage applications due to their insulating properties and simultaneous dimensional stability under high temperatures.
Thermoset materials can be designed as thermally conductive/insulating materials using selected fillers and ingredients. They protect high-quality add-on parts or overmolded electronic components from “heat death”. Thermoset materials can be real problem solvers, especially in applications with high currents or generally high operating temperatures.
