In glass fiber manufacturing, the sizing formulation plays a critical role in the performance of the final composite. Among all the ingredients, silane coupling agents are the key because they create a strong bond between inorganic glass fibers and organic resin systems such as epoxy, polyamide (PA), and polyurethane (PU). Two of the most widely used silanes are KH-550 (Amino Silan

Foam can reduce production efficiency and product quality in industries such as textiles, wastewater treatment, coatings, and cleaning chemicals. That's why dimethyl silicone fluid (PDMS) is widely used as the key ingredient in silicone defoamers. The performance of a defoamer depends largely on choosing the right viscosity and using an effective emulsification process. How V

If you work with addition-cure liquid silicone rubber (LSR), you've probably run into one of the most frustrating problems: the silicone simply won't cure. Sometimes it stays sticky on the surface, and sometimes it doesn't cure at all. In most cases, this isn't caused by poor-quality silicone. The real issue is something called platinum catalyst poisoning. Addition-cure silic

In industries such as composites, coatings, and adhesives, silane coupling agents are often called the "bridge" between organic polymers and inorganic materials. Their job is to create a strong chemical bond between the two, improving overall performance. However, if you use a low-quality silane coupling agent—or simply choose the wrong one—it won't strengthen the interface as inte

Silicone oil is a polymer material, so analyzing its composition is essential for quality control, process optimization, and regulatory compliance. Today, silicone oil testing goes far beyond traditional chemical titration methods. Most laboratories rely on advanced chromatographic and spectroscopic instruments to obtain accurate and reliable results. As long as testing is performe

Yellowing, oily residue, white powder on the surface, and unpleasant odors are some of the most common quality issues found in silicone rubber products. These problems don't just affect the product's appearance and feel—they can also raise concerns about product quality and safety. In most cases, these issues are related to the curing system, raw material quality, and post-processi

One of the most common questions in the silicone industry is whether there's still a significant gap between domestic silicone oils and well-known international brands such as Dow. The answer depends on the application. From today's market perspective, domestic silicone oils have become highly competitive in most standard industrial applications. However, for highly specializ

In industries such as silicone rubber, coatings, adhesives, and other polymer materials, silica (SiO₂) is one of the most important reinforcing fillers. Among the available options, fumed silica and precipitated silica are the two most widely used. Although both are silica, their manufacturing processes give them very different properties, performance, and costs. Choosing the right type

France has some of the strictest regulations in the world for food contact materials (FCMs). Under DGCCRF Regulation 2004-64 and Guideline AP2004-5, the content of volatile organic compounds (VOC/VOM)—especially low-molecular-weight cyclic siloxanes such as D3-D10—must not exceed 0.5 wt%. In recent years, more silicone products have been rejected or returned because their VOC levels exce

The introduction of silicone hydrogel materials has been one of the biggest breakthroughs in the contact lens industry, helping solve the long-standing problem of corneal oxygen deprivation. As the key component responsible for oxygen transport, polysiloxane plays a critical role in determining oxygen permeability, wearing comfort, and biocompatibility. That's why polysiloxanes used in silicone
