From polymer electronical performance to flame resistance and heat transfer, our diverse portfolio meets the complex and challenging demands of wire and cable applications.
Cables typically have metallic wires at their core through which electrical energy flows and are often surrounded by insulation material to guide and protect the current flow. One of these insulation layers is often made of cross-linked polyethylene (PEX), which is extremely temperature- and chemical resistant and also improves the electrical properties of the cable. Silanes like DYNASYLAN® enhance the stability of PEX against mechanical stress.
Moreover, silanes are also used in halogen-free flame-retardant cables (HFFR). HFFR cables are usually made from polymers such as polyethylene or ethylene-vinyl acetate (EVA). The plastic is filled with mineral fillers that release water at elevated temperatures, which can extinguish many cable fires in their early stages. If a fire does occur, HFFR cables produce significantly less smoke—thanks in part to the special silanes and silane oligomers from the DYNASYLAN® range.
Enhancing Cable Insulation and Jacketing with VISIOMER® Specialty Methacrylates
Traditional materials like polyethylene (PE) and plasticized PVC are commonly used in cable insulation and jacketing but are limited by their thermoplastic properties. VISIOMER® Specialty Methacrylates—including VISIOMER® TMPTMA and VISIOMER® TRGDMA—serve as powerful crosslinking agents and radiation sensitizers.
These additives convert thermoplastics into thermoset materials that offer superior thermal stability, mechanical durability, and chemical resistance. Their high efficiency allows for improved crosslinking density and reduced radiation dosage, even at lower concentrations.
In PVC plastisols, multifunctional methacrylates such as 1,4-BDDMA, EGDMA, and PEG 200 DMA replace volatile plasticizers, significantly boosting adhesion, hardness, and mechanical strength. These enhancements make them ideal for high-performance cable coatings in demanding environments.
