Types and classification basis of rubber softener

Rubber softener is one of the most common chemical substances closely related to our life and production, but there is still a lack of authoritative or professional information about rubber softener. It is difficult to find articles related to it on the Internet, which is a big obstacle to people's understanding of it. The following small make up to give you a simple introduction about its classification of knowledge.

Types and classification basis of rubber softener

I. Classification according to mechanism of action

1. Physical plasticizer: plasticizer molecules into the rubber molecules, increase molecular spacing, weaken the intermolecular force, this rubber softener can make the molecular chain easier to slide.

2. Chemical plasticizer: also known as plastic solution, this rubber softener through mechanochemical action, so that the rubber macromolecule chain, increase plasticity.

Most of the aromatic thiophenol derivatives such as 2- naphthalene thiophenol, diphenylthiophenol, pentachlorothiophenol, etc.

Ii. By source:

1. Petroleum plasticizer

2. Coal tar plasticizer

3. Turpentine plasticizer

4. Adipose oil is plasticizer

5. Synthetic plasticizer
