Description

T321 Sulfurized Isobutylene (Standard Process)

Product Overview

T321 is an advanced sulfur-based additive synthesized through catalytic reactions of sulfur monochloride, isobutylene, and sodium sulfide, followed by reactinons such as addition, sulfurization, and dechlorination. As a key extreme pressure (EP) and antiwear agent, it is widely used in gear oils and industrial lubricants. The product is an orange-amber transparent liquid with superior performance characteristics.
