German speciality chemicals major Wevo-Chemie has expanded its materials portfolio with the launch of WEVOSIL 23010 and WEVOSIL 23030, two liquid silicone rubbers engineered for modern textile coatings and high-precision sealing applications.

The company says the new LSR systems are designed to boost automation, durability and production accuracy across industries ranging from smart textiles to fuel cell technology.

Both materials offer a wide operating temperature range of –60°C to +200°C and show strong results in thermal shock testing, making them suitable for demanding environments. Their formulation is optimised for consistent dispensing onto textiles, plastics and metals — a requirement increasingly critical for high-volume, automated manufacturing.

WEVOSIL 23010, an extra-soft LSR is engineered for textile applications requiring flexibility and strong mechanical performance. Despite its softness, the material delivers an elongation at break of more than 900% and a tensile strength of 5.5 N/mm². It also adheres well to textiles and polymer surfaces without primers, accelerating production workflows.

Wevo positions 23010 as a key enabler for smart textiles, from firefighter and military protective gear to advanced sportswear. Its ability to bond textile layers and encapsulate embedded electronics allows manufacturers to integrate sensors, wiring and functional elements directly into fabrics.

The second new material, WEVOSIL 23030, is offering higher strength while maintaining excellent elasticity. It reaches an elongation at break of over 500% and a tensile strength of 5.0 N/mm². After post-curing, it delivers strong adhesion to metals and plastics, making it suitable for sealing and coating components exposed to high thermal and mechanical loads.
