  • GS has partnered with Latvian startup Phystep to incorporate Compo-SiL silicone rubber technology into their sportswear.
  • This collaboration aims to redefine sportswear by integrating kinesiology into activewear, offering athletes a 20 per cent increase in caloric burn with every movement.
  • The silicone rubber technology offers versatility for innovation.
General Silicones (GS), a globally recognised leader in silicone products for over half a century, has announced a transformative collaboration with Latvian activewear startup Phystep. By leveraging GS’s state-of-the-art Compo-SiL silicone rubber technology, Phystep is redefining the meaning of sportswear.

Harnessing customised silicone elastic film, Phystep ingeniously integrates kinesiology into their design protected activewear. The groundbreaking Compo-SiL adhesion technology propels this audacious endeavour, affording athletes an unparalleled edge—a 20 per cent increase in caloric burn with every stride or stretch with their leggings, the company said in a press release.

The Compo-SiL SR series combines resilience, stretchability, and skin-friendliness in a durable material that retains shape and elasticity—even after extended wear and multiple washes.

“We’ve tried dozens of materials, but only the Compo-SiL SR series delivered the essential shape retention and skin-friendly features that set it apart in our industry,” said Agris Muskars, founder of Phystep.

Ideal for both medical and athletic applications, the SR series is the go-to choice for companies aiming to enhance their products with kinesiology taping or elastic therapeutic tape. Its versatility makes it suitable for a wide range of end-products, from medical and sports protective gear to compression garments and supportive apparel like leggings and joint supports.

The malleable properties of Compo-SiL’s silicone rubber offer a vast canvas for innovation. The 1.4m wide, easy-to-cut Compo-SiL sheets ship in rolls readily adaptable to existing roll-to-roll mass production. The patented technology of Compo-SiL allows the silicon rubber to bond firmly and securely to textile surfaces through standard PUR or hot melt adhesion.

“Typical heat transfer materials come in sizes of 1m x 0.5m, which limits resource optimisation. The Compo-SiL SR series, however, is produced in a more accommodating 1.4-metre width, making it easier for us to cut efficiently,” added Muskars.

Phystep’s pioneering application showcases the extensive versatility of Compo-SiL technology. Beyond its current utility, Compo-SiL sheets can be enhanced to incorporate various value-additions like antibacterial and antiviral functionalities, flame resistance, and anti-slip properties. GS encourages forward-thinking product managers across sectors to seize this moment to catalyse innovation and diversification through Compo-SiL.
