Extreema® round slings are constructed using advanced parallel-laid fiber technology, forming the sling’s core. The core of every Extreema® round sling is made exclusively of 100% high-performance fibers, including Dyneema®, known as the world’s strongest fiber™, and Trosar® (general HMPE). These superior fibers ensure exceptional strength and durability, making Extreema® round slings an ideal choice for heavy-duty lifting and rigging applications.
Bio-Based Dyneema® Core
Bio-Based Dyneema® is an Ultra High Molecular Weight PolyEthylene (UHMWPE) fiber renowned for its unmatched strength-to-weight ratio. Developed by DSM in the Netherlands, this bio-based wonder fiber is often called “the world’s strongest fibre”™. Dyneema® yarn is manufactured in the EU and US, ensuring availability and quality for customers worldwide.
The secret behind Dyneema®’s superior performance lies in its incredibly long molecular chains, which distribute loads more efficiently across the polymer backbone. This results in a fiber that offers maximum strength and minimal weight, making it a top choice for high-performance applications where strength and weight are critical factors. Trust Dyneema® to deliver exceptional performance in the most challenging conditions.

Aramid Core
Aramid is a synthetic fibre known for its remarkable strength and heat resistance. Aramid fibres are commonly used in high-performance applications that require exceptional durability. The aramid core is known for its high strength-to-weight ratio, excellent cut resistance, and abrasion resistance. The combination of aramid and other high-performance fibres creates a round sling that is strong, lightweight, and versatile. Trust aramid core for reliable performance in the most challenging applications.
HMPE Core
High-modulus PolyEthylene (HMPE) is a strong and durable material due to its long chains, which efficiently transfer loads and enhance interactions between molecules. This results in a rigid material with the highest impact strength of any thermoplastic.
HMPE is highly resistant to corrosive chemicals (excluding oxidizing acids), has low moisture absorption and friction, and is self-lubricating and abrasion-resistant. Although there’s limited long-term research, HMPE is manufactured to consistent quality standards by DSM in the Netherlands in Asia, making it reliable and high-performing in various applications.
