Vulcanization

Vulcanization or vulcanisation is a chemical process for converting rubber or related polymers into more durable materials via the addition of sulfur or other equivalent "curatives." These additives modify the polymer by forming crosslinks between individual polymer chains. Vulcanized material is...

   (29 CFR 1910.1200).

Direct contact should be avoided. Goggles, respirator, and gloves should be used. Primary health risks are:

• Sneezing and coughing (move to fresh air)
• Eye irritation (wash immediately)
• Skin irritation (wash with soapy water)
• Ingestion (drink large quantities of water and induce vomiting)

Properties

Sodium lignosulfonate has the following properties.

• CAS# 8061-51-6
• Flammable
  Flammability
  Flammability is defined as how easily something will burn or ignite, causing fire or combustion. The degree of difficulty required to cause the combustion of a substance is quantified through fire testing. Internationally, a variety of test protocols exist to quantify flammability...
