Usage

Description

DI-OCTYL TIN DIACETATE, also known as Dicetyl tin oxide or Bis(2-ethylhexyl)tin diacetate, is a chemical compound that serves as a stabilizer in the manufacturing of polymers, such as plastic and PVC. It is a colorless liquid with a slightly aromatic odor and is recognized for its ability to prevent material degradation caused by heat or other adverse conditions. However, it is also known to be harmful if swallowed or if it comes into contact with the skin or eyes, leading to strict regulations and safety handling recommendations in many countries due to its toxicity and potential environmental effects.

Uses

Used in Polymer Manufacturing Industry:
DI-OCTYL TIN DIACETATE is used as a stabilizer for preventing the degradation of materials like plastic and PVC during manufacturing processes. Its application reason is to ensure the durability and quality of the final product by protecting the polymers from heat and other adverse conditions that could cause degradation.
Used in Plastic Industry:
DI-OCTYL TIN DIACETATE is used as a stabilizer in the production of various types of plastic materials. The application reason is to maintain the structural integrity and performance of the plastic products by preventing damage caused by heat or other environmental factors.
Used in PVC Production:
DI-OCTYL TIN DIACETATE is used as a stabilizer in the manufacturing of PVC (polyvinyl chloride). The application reason is to enhance the stability and longevity of PVC products by reducing the risk of degradation and ensuring a consistent quality throughout the production process.
