Cause: Summer heat broadens molecular weight distribution (more low-MW fractions) and softens wax during production/storage. Humidity adds to stickiness. Not caused by: Melt viscosity or normal oil content. Negative effects: Disrupts plasticization, sticks to equipment, poor dispersion; causes blooming, lower thermal stability, printability issues. Solution: Adjust process, ensure cooling, store at low temperature.

A technical analysis of oxidized polyethylene wax selection criteria for polyolefin garment fiber masterbatch systems. The article focuses on the precise adaptability of SCG ox102P across critical indicators—low viscosity (≈200 cPs), high thermal decomposition temperature (>250°C), and moderate acid value (≈16 mg KOH/g)—and presents a side-by-side comparison with two typical general-purpose oxidized wax products on the market. It reveals the fundamental reason why products within the same oxidized wax category are not interchangeable: the magnitude of difference in viscosity and thermal stability constitutes an insurmountable process barrier. This analysis serves as a technical reference for raw material selection in fiber masterbatch enterprises.

Monoglyceride‌ is a natural emulsifier that leverages its "lipophilic-hydrophilic" dual nature to bind water and oil. Produced via ‌conventional synthesis‌ and ‌molecular distillation purification‌, the ‌high-purity form‌ (over 90%) delivers superior performance in food, cosmetics, and pharmaceuticals compared to the ordinary grade (40%), making it an "invisible helper" in enhancing product texture and stability.

‌Acid value is the core indicator determining the performance of plastic additives‌, as its level directly affects the additive's polarity, lubrication type, compatibility, and thermal stability. ‌High acid value (16–30 mgKOH/g) in high-density oxidized polyethylene wax‌ enhances internal lubrication, significantly accelerating PVC plastification, making it suitable for highly filled rigid products such as SPC flooring and pipes. ‌Low acid value (10–15 mgKOH/g) in low-density oxidized wax‌ emphasizes external lubrication, improving demolding and surface gloss, ideal for film applications. ‌EBS, oleamide, and erucamide‌ require strict control of acid value ‌≤7.0 mgKOH/g‌ to ensure minimal blooming, high thermal stability, and reliable performance—functioning respectively as lubricant-dispersants in PVC processing, fast-acting slip agents in general PE films, and long-lasting anti-blocking agents in high-speed packaging films. The acid value is deeply tied to the molecular structure and application environment of the additive. ‌Precise matching of acid value enables optimal balance between processing efficiency and product quality‌.
