HDPE 56200
HDPE 56200 is a premium-grade, narrow molecular weight distribution high-density polyethylene resin formulated explicitly for high-velocity injection molding architectures. Equipped with built-in thermal stabilization compounds, this grade offers an outstanding melt index of 20 g/10 min, ensuring excellent melt fluidity, low molding orientation stress, and optimal automated cycle speeds. Balancing a rigid structural density of 0.956 g/cm³ with an adaptive 970 MPa flexural modulus, it delivers high dimensional precision, stable heat deflection properties (64°C), and verified impact endurance. It is the definitive industrial grade for manufacturing plastic beverage closures, container caps, food packaging boxes, premium housewares, and high-safety children's toys.
