Overview
Cable elastomer granules are thermoplastic polymer compounds engineered for extrusion into cable jackets and insulation layers. They combine rubber-like elasticity with plastic processability, making them ideal for dynamic cable applications requiring repeated bending (e.g., robotics, trailing cables). Primarily based on TPE (thermoplastic elastomer), TPV (thermoplastic vulcanizate), or TPU (thermoplastic polyurethane), these granules are formulated to meet international standards like IEC 60502 and UL 62. Their popularity stems from replacing traditional PVC in eco-conscious markets due to halogen-free formulations.
Physical and Chemical Properties
These granules exhibit Shore A hardness ranging from 60 to 90, with elongation at break exceeding 300% in premium grades. Their volume resistivity (>10¹⁴ Ω·cm) ensures excellent electrical insulation, while additives provide UV stability for outdoor use. Key testing parameters include tensile strength (typically 5–15 MPa) and cold resistance (-40°C to -60°C for Arctic-grade variants). Flame-retardant versions achieve VW-1 vertical flame ratings through hydrated alumina or phosphorus-based compounds without compromising flexibility.
Main Applications
Industrial automation cables account for ~45% of consumption, where granules provide oil resistance and torsion stability. Offshore wind farms use them for submarine cable sheathing due to saltwater resistance. Automotive applications include high-temperature engine compartment wiring (125°C rated). Emerging uses include data center cables (halogen-free low-smoke formulations) and medical device wiring (implant-grade biocompatible versions). Solar cable sheathing leverages their weather resistance, with UV-stabilized grades lasting 25+ years in direct sunlight.
Safety and Storage
Most commercial grades are REACH-compliant and non-hazardous at room temperature. However, processing above 200°C requires local exhaust ventilation due to potential fume emission. Storage pallets should be kept 10cm above floors in humidity-controlled warehouses (<60% RH). Bulk shipments typically use 25kg moisture-proof bags with 12-month shelf life. Cross-contamination risks necessitate separate storage from PVC compounds. Fire safety protocols should address melt dripping hazards during thermal decomposition.
B2B Procurement Guide
Industrial buyers should specify: 1) Required certifications (UL, CE, CPR), 2) Color stability requirements, 3) Minimum order quantities (often 1-ton pallets), and 4) Lead times (2–8 weeks for custom formulations). Sample evaluation should include extrusion trials to check for die buildup. Reputable suppliers provide batch-specific test reports covering dielectric strength (≥20 kV/mm) and hot set tests (≤175% elongation after heating). For large projects, consider dual sourcing to mitigate supply chain disruptions.
