HyPer C100 – a high-temperature resistant, multi-functional flow and dispersion aid (Winner of the First Prize for Technical Invention in Hubei Province). Product overview: HyPer C100 is an energy-saving and environmentally friendly lubricant with a high molecular weight, featuring a \"super-branched\" structure; it was developed independently by the company and holds independent intellectual property rights. It combines multiple functions such as enhancing flow, increasing elongation rate, improving 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 cycloaliphatic (CBT) resins, EBS, and silicones, and it can be applied to various material systems including PA, PC, PET, PBT, PC/ABS, and PC/PMMA. Its quality has reached an internationally advanced level; it boasts over 30 patented technologies and is at the global forefront in this field. It is already being used by well-known companies in the United States, Italy, Sweden, Vietnam, China, and other countries. Basic physical properties: Solid particles or powder with a density of 1.1 g/cm3, a melting range of 140–180°C, high heat resistance, and no volatility. Performance features: low melt viscosity, no VOCs, with a thermal decomposition temperature of up to 300℃ ； Effectively reduces melt pressure and main machine current, improves melt flow properties, and significantly enhances processing performance ； Significantly improves the dispersion of pigments, fillers, or glass fibers within the system, thereby enhancing the material properties ； Increase the surface gloss of the product, improve its appearance, and eliminate sharkskin and floating fibers ； Increase the filler content ratio to reduce the overall cost of the product and improve its quality. Application Example 1: Preparation of nylon composites with a high fiber content (≥50%) (data from a company in South Korea). The overall performance of HyPer C100 is superior to that of many lubricants available domestically and internationally, such as CBT-100 resin and dendrimers; it also features a high surface finish without any sharkskin effect or floating fibers, and it does not affect mechanical properties such as tensile strength and impact strength. Application Example 2: Preparation of nylon composite materials containing nylon + 50% glass fibers (data from a company in Tianjin). Testing parameters: PA-6+50%GF, PA-6+50%GF+0.7%HyPer C100, PA66+50GF, PA-66+50%GF+0.7%HyPer C100. Melt index (275°C/2.16 kg): 9.7, 16.8, 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 the material by 80%, effectively eliminating the problem of loose fibers on the surface of high-glass-fiber-reinforced nylons; it also improves the tensile strength, flexural strength, and impact strength. Test items: PA-66+50%GF, PA-66+50%GF+1wt%C100, PA-66+50%GF+2wt%C100. Melt index (275°C/2.16 kg): 2, 4, 16 respectively. Tensile strength (MPa): 232, 237, 237. Flexural strength (MPa): 349, 353, 338. Impact strength (kJ/m²): 5.932, 5.636, 5.476. Application example 3: Preparation of highly flowable reinforced nylon-66 (data from a company in Shenzhen). By adding 1wt% of HyPer C100 to PA-66+50% short glass fibers, the melt index can be doubled; when 2wt% is added, the melt index can be increased by 7 times, with no changes in other properties. Adding 0.7% HyPer C100 to a black nylon-6+30% long glass fiber matrix effectively resolves the issue of floating fibers, improves the surface gloss of the product, and doubles the melt index, while other properties remain unchanged.
