The chemical composition of high-temperature penetrant JFC-M (CAS No.: 5689-56-3) is isomeric tridecanol polyoxyethylene ether. Compared to common traditional JFC penetrants available in the market (typically made from C8-C10 linear fatty alcohol polyoxyethylene ethers or ordinary isomeric alcohols), its molecular structure features significant branching characteristics. The branched chain structure of isomeric tridecanol endows JFC-M with a lower critical micelle concentration (CMC is only 0.005%~0.01%) and superior surface activity. It can rapidly reduce the surface tension of the working solution (28~32 mN/m) at very low dosages, achieving fast penetration with a penetration index requiring only ≤5 seconds, far exceeding conventional products.
The most prominent core competitiveness of JFC-M lies in its dual tolerance to high temperature and high alkali. The product's cloud point reaches as high as 85~95℃. Even under high-temperature and high-pressure dyeing conditions (typically 130℃), it still maintains good penetration activity and does not precipitate or fail due to a low cloud point. At the same time, its alkali resistance can reach 200g/L NaOH, performing stably in high-alkali pretreatment processes such as desizing and scouring. In contrast, the penetration power of most traditional penetrants decreases significantly when the alkali concentration exceeds 80~100g/L, and they may even undergo hydrolysis or salting out. This dual tolerance characteristic of "high temperature + high alkali" endows JFC-M with excellent process adaptability in one-bath processes.
In addition, JFC-M offers the advantages of low foaming characteristics and high active content (≥99%). The low-foaming formulation reduces the additional addition of defoamers during production, lowering overall costs; high purity means fewer impurities and low free alcohol content (≤1.0%), which has little impact on subsequent processing. Its compatibility in various fields such as textiles, papermaking, and pesticides is significantly better than that of ordinary penetrants. From a safety perspective, the product is a non-hazardous chemical with low acute toxicity (LD₅₀ > 2000 mg/kg), ensuring safety during actual operation.
