This is a class of ultra-speeding accelerators that are acidic. The vulcanization rate is extremely fast, the flattening range of the vulcanization curve is small, and the scorch time is short, so the rubber is prone to early vulcanization during processing, and the vulcanization operation is unsafe.

Pará rubber tree (Hevea brasiliensis) In the wild, the rubber tree will grow to heights of 100 to 130 feet, and can live up to 100 years. Its most famous feature is the milky white sap, known as latex, which flows freely from the tree when a sliver of bark is removed. A rubber tree, also referred to as rubberwood, can be tapped for latex once it reaches approximately six years of age.

dithiocarbamate

Dithiocarbamate

A dithiocarbamate is a functional group in organic chemistry. It is the analog of a carbamate in which both oxygen atoms are replaced by sulfur atoms (when only 1 oxygen is replaced the result is thiocarbamate). A common example is sodium diethyldithiocarbamate.
