High Purity Diethylene Glycol DEG for Antifreeze, Coolant & Hydraulic Brake Fluid Production,
,

Diethylene Glycol (DEG) is a vital raw material for preparing industrial antifreeze, engine coolant and hydraulic brake fluid, well known for its low freezing point, high boiling point and outstanding heat transfer performance. It is miscible with water in any proportion, and the mixed solution can form a stable low-freezing system to protect pipelines, equipment and mechanical systems from frost damage in low-temperature environments. In brake fluid manufacturing, DEG serves as the base polyol component, contributing to stable viscosity within a wide temperature range, good lubricating property and excellent compatibility with rubber sealing parts, which prevents swelling or aging of rubber seals in hydraulic braking systems. Our high purity diethylene glycol has low acidity and low ash content, avoiding corrosion to metal pipelines and equipment. It can be applied in industrial circulating cooling systems, pipeline antifreeze solutions and automotive brake fluid formulas. The product is sealed in export-grade drums and IBC containers with anti-corrosion lining. We support long-term bulk orders for coolant factories, brake fluid manufacturers and industrial fluid producers worldwide, offering professional technical support on mixing ratio and storage requirements.
