properties:
white needle-like crystal powder , relative density 1.32-1.38.
uses:
used as the sulphidizing agent and accelerating agent for natural rubber and synthetic rubber. it can decompose active sulfur with the assay of 27%. it can be used safely and happen no coke even it is working with high abrasion furnace black. because slow curing speed, it mostly is working with accelerant such as thiazole type, thiram type and dithiocarbamate, etc. foe better performance, you can add sulfur. salicylic acid type of products can decompose this product and speed the curing rate, but can offer bad effects on physical performance. no frost, color change, pollution and easy to disperse. it is suitable for tire, thick products, cable, wire, heat-resisting product and thin products, particularly applicable to butyl rubber, with good resistance to heat, age and distortion. sulphur donor vulcanizing agent for efficient vulcanization and semi-efficient vulcanization cure system; provide heat/reversion/aging resistance in nr and synthetic rubbers; non-blooming; excellent storage safety.
dosage is 2-4%, or 0.5-2%.
packing:
pe film bag lined pp woven bag or laminated kraft bag, net wt 25kg.
storage:
stored in cool and dry place, avoid fire, insolation and moisture.
