Edgetek™ PKE Glass-Filled Formulations The Edgetek PKE Glass-Filled (GF) series consists of specialty engineered, glass-reinforced polyketone (PK) thermoplastics.

Edgetek™ PKE High Impact Formulations The Edgetek™ PKE High Impact (HI) series consists of specialty engineered, impact modified polyketone (PK) thermoplastics.

Suitable for both vertical and horizontal cable systems, the materials offer safe, sustainable and efficient solutions for low voltage power cable systems, including in solar and other specialty market applications.

Beyond finding the best material combination—Bergamid™ nylon copolymer and GLS™ TPEs—our global presence and expertise across an array of specialty polymers and colorants, combined with local service and support, helped Victorinox to accelerate development work, streamline production and reach their design goals.

LubriOne™ PKE Formulations The LubriOne PKE series consists of specialty engineered, internally lubricated polyketone (PK) thermoplastics.

GLS™ TPEs with Antimicrobial Technologies This specialty line of GLS™ thermoplastic elastomers has imbedded antimicrobial additives that inhibit bacterial growth by 99.9% or more (log 3) and resist fungal growth to protect molded plastic parts.
