Excellent High Viscosity & Melt Strength: The stable viscosity of 2.85 provides robust melt support, preventing strand breakage during high-speed extrusion and ensuring uniform drawing. It is perfectly suited for demanding monofilament and film casting processes.
Exceptional Mechanical Toughness & Impact Resistance: This grade exhibits outstanding tensile strength (60.7 MPa) and elongation at break (48.1%), enabling it to withstand intense physical stretching and external impacts, resulting in highly wear-resistant and durable finished products.
Good Self-lubrication & Chemical Resistance: It possesses natural resistance to motor oils, lubricants, aromatic solvents, and various chemicals, coupled with a low coefficient of friction, making it ideal for industrial components in contact with chemical media.
Superior Surface Gloss & Processability: Despite its high viscosity, the chips feature exceptional purity with low gel levels and minimal residual monomer, ensuring smooth, fine surfaces on injected or extruded products while lowering defect rates.
Modern Fishery & Textile Monofilaments: Benefiting from its high viscosity and high tensile strength, YH800 is extensively used to manufacture premium marine fishing nets, trimmer lines, industrial filter meshes, and high-end textile monofilaments.
Specialized Packaging Films: Utilized in the production of Biaxially Oriented Nylon (BOPA) films, primarily applied in food barrier packaging and medical packaging where high barrier properties and puncture resistance are required.
Automotive & Mechanical Components: After fiberglass reinforcement or flame-retardant modification, it can be applied to manufacture automotive engine peripheral components, bearing cages, gears, and various high-load industrial fasteners.
Electrical & Electronics Enclosures: Used for manufacturing switch panels, connector housings, and cable ties that require high heat resistance and sound electrical insulation performance.
Q1: Does Sinopec Baling PA6 YH800 require drying before processing? What are the recommended drying conditions?
A: Yes, polyamide 6 (PA6) is highly hygroscopic. To prevent bubbles, silver streaks, degradation, or embrittlement during processing, the material must undergo strict drying. Although the factory water content of YH800 is controlled under 0.07%, due to international logistics (such as high-humidity marine transit) or exposure after unsealing, it is recommended to dry it in a desiccant or hopper dryer at 80 °C – 90 °C for 4 – 6 continuous hours, or in a vacuum dryer at 80 °C for 3 – 4 hours, ensuring the moisture content drops below 0.05% before processing.
Q2: As a high-viscosity grade, what is the recommended temperature range for YH800 during injection molding?
A: The melting point of Yuehua PA6 YH800 lies between 215 °C and 220 °C. Due to its high molecular weight and slower flowability compared to low-viscosity injection molding grades, it is advisable to increase the processing temperature and injection pressure appropriately. Typical barrel temperature settings are as follows:
Rear (Feed Zone): 220 °C – 235 °C
Middle (Compression Zone): 235 °C – 250 °C
Front (Metering Zone): 245 °C – 260 °C
Nozzle Temperature: 245 °C – 255 °C
Mold temperature is recommended to be maintained at 60 °C – 80 °C to achieve optimal crystallinity and surface gloss.
Q3: Does this product comply with international environmental and export compliance standards, such as RoHS / REACH?
A: As a premium virgin material manufactured by a top-tier Chinese state-owned petrochemical enterprise, Sinopec Baling PA6 YH800 strictly complies with international quality and environmental management systems. The material fully aligns with the EU RoHS Directive, REACH Regulations, and halogen-free standards, containing no heavy metals, polybrominated biphenyls (PBBs), or polybrominated diphenyl ethers (PBDEs). We can provide complete third-party authoritative testing reports and compliance certificates based on the entry requirements of your overseas buyers or markets in the Middle East and Europe.
