Traditional silicone-based defoamers are widely used for their low surface tension and rapid bubble-breaking ability. However, they often “malfunction” in complex coating formulations due to poor compatibility. The key lies in their hydrophilic-lipophilic balance (HLB): If the EO content is too high, the silicone oil becomes overly soluble in waterborne systems, preventing it from

As the new energy vehicle and large-scale energy storage sectors accelerate, battery thermal management has become critical to safety and service life. As a core component of thermal interface materials (TIMs), silicone oil is not something that can be “added arbitrarily”—its viscosity selection directly determines the thermal resistance performance and long-term reliability of the therma

Under the U.S. regulatory framework, food-grade silicone oil must comply with 21 CFR §177.2600 of the Code of Federal Regulations. The core requirement involves testing under simulated food-contact conditions (e.g., immersion in hot oil for 7 days), ensuring that non-volatile residues remain below specified limits to prevent harmful migration. However, this standard does not includ

“Many factories assume that the ‘thicker’ the silicone oil, the better the performance—but it’s actually the opposite,” notes an organosilicon application engineer. Experimental data show that when release agents are formulated with silicone oils having viscosities above 1000 cSt (high molecular weight), they form relatively thick films (>1.5 μm) on mold surfaces. Due to their long polymer cha

“As soon as we switch to a new batch of silicone oil—even with the exact same formulation—the emulsion breaks. More often than not, the problem isn’t the process; it’s the raw material,” shared a cosmetic formulator based in Eastern China. To address this pain point, several domestic high-purity silicone oil suppliers have now established dedicated quality control standards specifically for

“Power modules failing right out of the factory? Encapsulant full of bubbles, cracking, or peeling after high-temperature aging?” Such failures are costly. Surveys show that VOCs exceeding limits cause >18% device failures, with single-batch losses reaching tens of thousands of dollars. Experts warn: low-volatility silicone is essential. Excessive volatile content is the main cause of board

“Does your silicone emulsion separate after standing, stick to rollers during finishing, or cause yellowing on white fabrics?” These issues are common in textile dyeing and finishing plants. Industry surveys show that improper use of silicone oils can push rework rates to 20%, with single incidents causing losses of tens of thousands of dollars. Experts emphasize that 90% of these problems are

The Core Reason Ordinary Silicone Oils Fail In precision injection molding and metal die casting, demolding stability directly impacts product quality and productivity. Industry data shows that improper demolding agents can cause defect rates exceeding 15%, with standard dimethyl silicone oils performing especially poorly under high temperatures. Experts agree that only modified silicone

In addition-cured silicone systems, the structure and purity of the crosslinker directly affect curing efficiency and final performance. End-functional hydrogen-containing phenyl silicone oil IOTA-234 (Chemical Name: 3,5-Bis(dimethylsiloxy)-1,1,7,7-tetramethyl-3,5-diphenyltetrasiloxane, CAS: 66817-59-2) is a high-purity, low-molecular-weight hydrogen-containing phenyl siloxane. Thanks to its we

As a key active component of addition-cured phenyl silicone rubber, Phenyl Vinyl Silicone Oil IOTA-252 (Di-vinyl-terminated Phenyl Methylsiloxane, CAS: 225927-21-9) offers well-defined structure, controllable reactivity, and batch-to-batch consistency, and has been reliably used for years in high-temperature, radiation-resistant, and high-insulation silicone rubber applications.
