No 32 Rubber Bands

Our no 32 rubber bands are made of 100% natural milk fabric (NR70 grade) precision manufactured, conforming to ASTM D2000 international material standards. Inner diameter 3/8 English size (9.5 mm), cut surface diameter 1/16 English size (1.6 mm), standard size, suitable for high-speed steel. The sulfurization technology has improved molecular structure under 150°C, and has a strength of 28-32 trillion volumes (according to ASTM D412 standard).

We have no 32 rubber bands that can be stretched after 72 minutes, with a 95% expansion rate, acceptable >500% expansion rate, and no permanent change. 3 times more abrasion resistant than mixed resin, withstands temperatures between -40°C and 100°C. Biodegradation was possible, and the filling rate was low at 67%. It is safer to use, anti-rupture design ensures high strength use, and no heavy metals.

The performance of the general merchandise is excellent, the tensile strength is 30±2MPa, the fracture elongation rate is 850±50%, the use of high iron is zero fracture, the end environmental performance is determined, and the drop-down stop mechanism is lost. Our products have high performance efficiency, 3 times more abrasion resistance than the mixed rubber, 5 times longer service life, 35% more efficiency, 22% less annual wear and tear, and 40% less manpower input. Our supply chain is strong, with a monthly production capacity of 3,000 tons, a 48-hour response time for urgent orders, a dimensional tolerance of ±0.03mm, which can effectively avoid out-of-stock losses, and 100% production line compatibility.
