From Mass to Class
Elastomers are long-chain polymers that have thermoplastic properties in the uncrosslinked state. They soften with increasing temperature and are thus extrudable. Only through vulcanization (crosslinking) is a narrow- or wide-meshed structure formed. Depending on the material, crosslinking is carried out by halogen-free peroxides or by radiation crosslinking. This gives elastomers many additional qualities, such as high temperature stability, flexibility and good mechanical resistance, even at very low temperatures. Due to their high elasticity, elastomers return to their original shape after tensile and compressive stress.
For example, elastomers are used for:
- Cables and lines for medical technology
- Military cables (navy/air force)
- Heating cables- link to heating cables
At Habia we have excellent expertise in the processing of elastomers. In our in-house compounding department, we develop and produce application-optimized sheathing and insulation materials, which are processed using state-of-the-art production equipment. This results in numerous application possibilities and products that are precisely tailored to the needs of our customers.
Manufacturing Competencies Elastomers
Solid silicones (HTV)
Solid silicones are copolymers of dimethylsiloxanes (main chain) and isolated vinylmethylsiloxanes (functional group). Due to their low intermolecular interaction, they have a soft, pasty consistency. With a viscosity of 10,000 to 50,000 Pa-s, solid silicones are easy to process at room temperature.
Liquid silicones (LSR)
Liquid silicones are usually 2-component systems consisting of the platinum catalyst (component A) and the Si-H crosslinker (component B), which are crosslinked exclusively by addition. Due to short-chain linear polysiloxanes with a viscosity of approx. 5-500 Pa-s and a relatively low filler content (max. 30%), liquid silicones have a pourable to pasty consistency and are mainly processed by injection molding.
