HOCP

Product Overview

Modern lubricant formulations require advanced polymer technologies capable of maintaining stable viscosity performance under demanding operating conditions, elevated temperatures, and long service intervals. The selection of an appropriate viscosity index improver plays a critical role in achieving consistent viscosity control, formulation stability, and reliable finished lubricant performance.

HOCP (Hydrogenated Olefin Copolymer) is a hydrogenated olefin copolymer viscosity index improver supplied by SiNDA through qualified international manufacturing partners for lubricant manufacturers and formulators.

Developed through hydrogenation technology, HOCP provides improved polymer backbone stability by reducing unsaturation within the polymer structure. This modification enhances resistance to thermal and oxidative degradation, allowing lubricant manufacturers to develop advanced formulations with improved viscosity retention and long-term performance stability.

Compared with conventional OCP viscosity improvers, HOCP technology is designed to provide enhanced polymer durability, improved high-temperature performance, and reliable viscosity modification in demanding automotive and industrial lubricant formulations.

HOCP supports lubricant manufacturers in developing modern multigrade lubricants requiring stable viscosity behavior, improved formulation durability, and consistent performance throughout the lubricant service period.

Compatible with commonly used base oil systems, including Group I, Group II, and Group III base oils, HOCP provides formulation flexibility for mineral, semi-synthetic, and synthetic blend lubricant technologies.
