Appearance: Yellow powder Application: Insoluble Sulfur can improve the resistance to both fatigue and ageing of all kinds of rubber products. It is used as the best vulcanizing agent for rubber. And it is widely used in the manufacture of the rubber chemistry such as tire, rubber pipe, shoes, cable and wire, insulating materials, latex, and all kinds of automobile rubber parts, especially for radial tires. Advantages: The rubber doesn't spout frost during storage time. It can keep the uniform function of the rubber material. And it prevents the pollution to the rubber product and the models. It has no moving phenomenon between rubber layer, and can protect the surfaces to form stickiness. Reduce coking during the mix smelting and storage time. Shorten vulcanization time, reduce the consumption of sulfur and improve the rubber product's anti-oxidize property. Packing: The wrapper is plastic woven bags or superior vellums, and the plastic bonded in two layers. The bags will be sewed by machine after be folded. We may differ according to your specific order.
