Physical and chemical properties and main hazardous
A little bitter taste. Specific gravity: 1.45--1.54. Grayish-white or pale yellow powder (particles), non-toxic, with a melting point above 160℃, soluble in chloroform, partially soluble in benzene, ethanol, carbon tetrachloride, insoluble in gasoline, water and ethyl acetate.
Application
Given flat, moderately fast cures in NR and SR. Also used in a wide range of general purpose rubber. Non-staining/non-discolouring in "white" socks; use as a plasticiser and/or retarder in polychloroprene rubber. Secondary acceleration is usually required for synthetic polymers. Better scorch safety than Accelerator MBT.
Packaging
25kg plastic woven bag, paper with plastic film bag, kraft paper bag or jumbo bag
Packaging should include:material state,thickness,losure,inner lining,outer,lining,securing and unit weight.
Storage
Keep container tightly closed in a cool, well-ventilated place. The recommended maximum storage life is 2 years when stored under normal conditions.
Emergency medical treatment
If it gets into your eyes, immediately rinse them with plenty of water for at least 15 minutes. If the symptoms do not disappear, you should see a doctor immediately. For example If it gets on your skin, remove the contaminated clothes immediately and rinse with clean water. You can also wash with soap.
Method of fire fighting
Firefighters should wear protective clothing, including self-rescue breathing equipment. They should extinguish the fire in a safe area and use water to cool it down. Do not pour it into the drainage ditch.
Method of leakage
If it is in the form of particles, use a vacuum cleaner or place it in a covered container for cleaning. Avoid generating dust. Handle it wearing protective clothing.
Formula should be indicated for a single substance and main components for a mix ture Properties should include state,color,odour,melting point,flash point,explosion
limits,poisonous concentration LD50/LC. The testing reports issued by technical inspection organizations should be attached. Compatibility between the cargo and others,description of the danger of the cargo in contact with others.
