3. Consumer Electronics Housings and Protective Casings

Thermoplastic elastomers provide electronic casing manufacturers with essential anti-slip properties, impact absorption, and precise color matching for device housings such as smartphone bumpers, wearable device straps, headphone shells, and wireless remote grips. These applications integrate the material for its ability to pass migration, abrasion, and sweat resistance tests, while supporting demanding in-mold lamination or continuous extrusion procedures typical in modern electronics manufacturing.

Industry compliance standards

• IEC 62321 (Determination of certain substances in electrical products—RoHS relevant)

4. Sealing Systems for Food and Beverage Packaging

Major food packaging manufacturers use thermoplastic elastomers in cap liners, dispensing valves, container gaskets, and flexible closure seals requiring direct food contact approval and resistance to food acids and cleaning solutions. Our materials are engineered to retain sealing integrity over repeated cycles, supporting both hot-fill and cold-fill packaging lines, and allow precise formulation for automated closure molding or liner compression applications in high-speed production environments.

5. Cable Sheathing and Insulation in Industrial Wiring

Wire and cable manufacturers specify thermoplastic elastomers for outer sheathing and inner insulation layers on power and signal transmission cables installed in automation, building construction, robotics, and harsh outdoor environments. These applications demand compliant flame retardance, flexibility at low temperatures, resistance to environmental cracking, and dependable color stability. Downstream operations benefit from steady melt flow and easy color compounding for continuous extrusion runs at industrial scale.
