product overview
Our small thick black rubber bands are precision-made from 100% natural rubber. Designed for industrial durability, each rubber band has a compact size (standard inner diameter 15–30mm), thickened cross-section (3–5mm), and matte black surface, suitable for high-intensity scenarios. Its tensile strength exceeds 18MPa, and its elasticity retention rate after 10,000 stretches is >95%, and its lifespan is more than 3 times that of ordinary rubber bands.
Product advantages
Our small thick black rubber bands have an average thickness of 4.2mm and a sulfur-enhanced vulcanization process that allows them to resist 25N tear force. They remain flexible and do not crack in environments ranging from -30°C to 120°C. They also have good anti-slip properties, and the laser-engraved micro-texture on the surface increases friction by 60% compared to smooth rubber, effectively preventing slipping on oily/wet surfaces. They are also corrosion-resistant and can withstand oils, weak acids (pH>3) and 1,000+ hours of UV exposure (equivalent to 3 years of outdoor use).
