HD Blow Moulding BL3 / HF4760

Polyethylene BL3 is also known as HF4760. HDPE BL3 is a heavy polyethylene copolymer with 1-butene as a comonomer. It is a blow molding grade resin that is manufactured by the suspension polymerization of ethylene monomer. This polymer comes with a density of 0.954 g/cm³ and its high load melt flow index (MFI) is 23 (190 °C/21.6 Kg). It is available in the form of granules (pellets) and contains additives such as antioxidants, process stabilizers, lubricants, and acid scavengers.

• Injection molding temperature: 200 – 2800 C   ​​​​​​​​​​​​​​

High density and stiffness

This attribute refers to the polyethylene’s rigidity and high molecular weight. Polyethylene with high stiffness can maintain its shape under loads and is less prone to warping or deformation under stress or temperature changes.

Good flowability

This feature refers to the ability of polyethylene to flow smoothly and efficiently during processing resulting in higher versatility and productivity. It comes with low melt viscosity and a high melt flow index.

Good impact strength

Polyethylene with excellent impact resistance can maintain complete integrity under sudden, high-force impact without failing or breaking because it can absorb and distribute the energy. Products made from this polyethylene are less likely to break or crack when dropped or struck.

Good stress crack resistance

High ESCR (Environmental Stress Crack Resistance) is an important property of high-density polyethylene materials. It is related to the resistance of a plastic material against cracking in exposure to stress and aggressive chemicals. Weather, chemical, and pressure resistance provide durability and safety for the products made of this polyethylene in various applications.

BL3’s high rigidity and good flowability make it suitable for use in bottles and small blow molding goods. It is generally recommended for the production of small containers (less than 5 liters) used for various products such as detergents, medicines, and surfactants. This grade is also suitable for food contact to conform to EEC regulations.
