◇Product Overview: HyPer C100 is an energy-saving and environmentally friendly lubricant with a high molecular weight and a \"super-branched\" structure, developed independently by the company. It is non-volatile and does not decompose, and it combines multiple functions such as improving fluidity, increasing elongation, enhancing dispersion, boosting compatibility, and increasing the level of filling. Its comprehensive performance is far superior to that of traditional lubricants with single functions such as spirocyclic (CBT) resins, EBS, and silicones, and it can be used in various composite material systems including PA, PC, PET, PBT, PC/ABS, and PC/PMMA. The products meet the international environmental standards of RoHS and REACH, as well as the ISO 9001 quality management system certification standards. The technology has been recognized as reaching international advanced levels; it holds over 30 patented technologies and is globally leading in this field. It has been widely applied by renowned companies in China, Italy, South Korea, Vietnam, and other countries. ◇Basic physical properties: solid particles or powder with a density of 1.0–1.1 g/cm3, a melting range of 160–180°C, and high heat resistance. ◇Performance features: (1) Low melt viscosity, no volatilization; initial thermal decomposition temperature is around 300℃ ; (2) Effectively reduces melt pressure and main machine current, improving melt flow and processing performance ; (3) Significantly improves the dispersion degree of pigments, fillers, or glass fibers in the system ; (4) Improve the surface gloss of the product, enhance its appearance, and eliminate sharkskin and floating fiber phenomena ; (5) Increase the filler filling ratio to reduce the overall cost of the product. ◇Application Areas and Advantages (1) The flow modifier for engineering plastics and their composites, HyPer C100, possesses strong wetting capacity. It is compatible with various fillers (calcium carbonate, talc, wollastonite, silica powder, glass microspheres), fibers (carbon fiber, glass fiber), stabilizers, flame retardants, release agents, and pigments. Its strong wetting ability enables it to effectively suppress the \"shark skin\" phenomenon in materials with high filler content. (2) As a dispersant for pigments (red, orange, yellow, black, blue, purple, etc.), a pigment dispersant requires only 0.2–1.0 wt% of the material added to achieve color masterbatches with good dispersion, resulting in vivid and rich colors that appear more realistic. (3) A very small amount of blended rheology modifier can significantly improve the fluidity, melt index, and mechanical properties of the resin ; It reduces energy consumption during blending and increases production capacity; it can also significantly lower the current or decrease the processing temperature by 10–20°C, resulting in notable energy and cost savings. ◎Application areas (1) Fiberglass-reinforced resin (PA, PP, PC, LCP, PBT, etc.) systems ; (2) Filler/pigment-filled resin (PP, PE, PET, etc.) systems ; (3) Blended modification (PC/ABS, PC/PMMA, PP/HDPE, etc.) systems ; (4) Spray-free materials (ABS/copper powder, ABS/aluminum powder, PA/magnetic powder, PP/pearl powder, etc.) ; (5) PVDF membrane (wastewater treatment membrane) ; (6) Nylon spinning industry, etc. ◎ Application examples: Application example 1: Preparation of nylon composites with a high glass fiber content (≥50%) (data from a company in South Korea). The overall performance of HyPer C100 is superior to that of CBT-100 resin and dendrimers; the product surface has a high level of smoothness, without any sharkskin effect or floating fibers, and its mechanical properties such as tensile strength and impact strength are not affected. Application Example 2: Preparation of nylon composites made of nylon + 50% glass fibers (data from a listed company in Tianjin). Testing parameters: PA-6+50%GF, PA-6+50%GF+0.7%HyPer C100, PA-66+50%GF, PA-66+50%GF+0.7%HyPer C100. Melt index (275°C/2.16 kg): 9.7, 6.8, 17.5, 31.2. Tensile strength (MPa): 217, 220, 174, 178. Flexural strength (MPa): 263, 283, 271, 282. Notch impact strength (kJ/m2): 18.3, 19.2, 13.1, 14.5. HyPer C100 can increase the melt index of PA-6/PA-66 systems with 50% glass fibers by 80%, effectively eliminating the problem of floating fibers on the surface of highly glass-fiber reinforced nylons; it also improves the tensile strength, flexural strength, and impact strength.
