This is a type of super speed accelerator, which is acidic. The vulcanization speed is extremely fast, the vulcanization curve has a small flat range, and the scorch time is short. Therefore, the rubber material is prone to early vulcanization during the processing process, and the vulcanization operation is unsafe. Improper control of vulcanization conditions can easily lead to under- or over-sulfur phenomena. If used properly, the physical and mechanical properties and aging resistance of the vulcanized rubber will be superior, and it will not pollute. It is suitable for the vulcanization of thin products, room temperature vulcanized products and latex products that are vulcanized at high temperature and short time. The most commonly used are the following zinc salt varieties: Zinc Dimethyldithiocarbamate The trade name is accelerator PZ. Also known as accelerator ZDMC. This product is white powder, tasteless and non-toxic. But contact with the skin can cause inflammation. The specific gravity is 1.65~1.74. The melting point is 240~255℃. The vulcanization critical temperature is about 100°C, and the vulcanization activity is similar to that of accelerator TT, but the activity is greater at low temperatures and the tendency to scorch is greater. This product is easily dispersed in rubber, and the product is tasteless, non-toxic and non-polluting. Mainly used in latex products, natural vulcanized glue, rubber cloth products and cold vulcanized products, light-colored and colored products, and edible rubber products. The dosage in the latex material is generally 0.3 to 1.5 parts.
