Everything you need to know about our products and company
Methyl hydrogen siloxane serves as a high-efficiency textile auxiliary, enhancing processing performance through its unique reactivity and surface properties. This specialty silicone oil significantly improves fiber lubrication, reducing breakage during spinning and weaving while increasing production efficiency.
Its exceptional spreading capability ensures even distribution of dyes and finishing agents, particularly on synthetic fibers and challenging textile surfaces, enhancing color fastness while reducing chemical usage by 20-30%. In waterproof finishing applications, it forms durable cross-linked networks that provide excellent water resistance while maintaining fabric breathability.
With heat resistance up to 200°C, it is suitable for high-temperature setting processes, while its complete volatility ensures no residue. Compatible with both natural and synthetic fibers, it offers textile manufacturers a sustainable solution for improving product quality and reducing costs.
