What are the melt temperature ranges for polyethylene in outdoor seating molding?
The melt temperature ranges for polyethylene (PE) in outdoor seating molding vary depending on the type of polyethylene used. For High-Density Polyethylene (HDPE), the typical melt temperature range is between 190°C and 260°C (374°F to 500°F). For Low-Density Polyethylene (LDPE), the range is slightly lower, usually between 160°C and 240°C (320°F to 464°F). These temperatures ensure proper flow and molding while maintaining the material's structural integrity.
Maintaining the correct melt temperature is crucial for producing durable and high-quality outdoor seating. Too low a temperature can result in incomplete molding, while excessive heat may degrade the polymer. Always refer to manufacturer guidelines for specific resin grades and molding techniques.
