Histif
Description
Histif is a high-density polyethylene brand built for a single job done well: extrusion blow-moulded L-ring drums and industrial containers for dangerous-goods transport. Where general-purpose HDPE distributors list a family of drum grades, Histif takes the opposite route with one grade, optimised end-to-end for the UN-approved dangerous-goods packaging use case. Genesis Polymers distributes Histif 5431 Z, purpose-built for the combination of stiffness, low-temperature drop performance and environmental stress crack resistance that dangerous-goods drums have to carry through their service life.
The dangerous-goods case is what defines Histif as a specialist brand within the HDPE family. UN-approved drums (1H1 closed-head and 1H2 open-head) have to pass drop tests from defined heights at −18 °C before they can carry hazardous liquids or solids across borders. That low-temperature drop requirement is where most HDPE grades struggle, since sub-zero brittleness is the usual failure mode, and where Histif's specific property profile is engineered to deliver.
Where Histif is used
L-ring drums: extrusion blow-moulded, 1H1 and 1H2 types for UN-approved dangerous-goods transport
Industrial dangerous-goods packaging: chemicals, fuels, hazardous liquids and solids
Large industrial containers: thick-wall extrusion blow moulding where low-temperature drop performance is a service requirement
Histif is not intended for food-contact or medical applications. The grade is built around industrial dangerous-goods duty.
Histif technical profile
Three properties have to hold together in a single resin across serial blow-moulded drum production:
Stiffness for structural integrity under stacking load
Low-temperature impact toughness to pass sub-zero UN drop tests
Environmental stress crack resistance (ESCR) to survive years of contact with aggressive chemicals
Histif 5431 Z delivers all three: tensile modulus 1200 MPa, notched Charpy impact of 80 kJ/m² at −30 °C (unusually high low-temperature toughness for an HDPE, where mainstream drum grades typically sit well below this value), and high ESCR. Density 0.954 g/cm³ and HLMI of 2.6 g/10 min give the high melt strength and stable parison formation needed for thick-wall extrusion blow moulding of large industrial drums. Antioxidant stabilisation is built in for processing stability during long production runs.
The Histif grade
Histif 5431 Z: HDPE for UN-approved dangerous-goods packaging. Tensile modulus 1200 MPa, notched Charpy 80 kJ/m² at −30 °C, density 0.954 g/cm³, HLMI 2.6 g/10 min. The reference grade for L-ring drums, 1H1 closed-head and 1H2 open-head containers, and large industrial dangerous-goods packaging where sub-zero drop performance is a UN certification requirement.
Choosing Histif vs. Hostalen
Application | Recommended grade |
|---|---|
UN-approved dangerous-goods L-ring drums with −18 °C drop requirement | |
General-purpose blow-moulded jerry cans and drums (no sub-zero drop requirement) | Hostalen ACP 5331 A, ACP 5531 B |
Heavy-duty industrial blow moulding without dangerous-goods certification | Hostalen ACP 5831 D, ACP 6031D |
Histif's sub-zero toughness carries a specification and cost premium over general-purpose HDPE. For drums that stay within normal service-temperature ranges and don't carry hazardous cargo, mainstream Hostalen grades are the more economical choice.
Frequently asked questions about Histif
What is Histif 5431 Z used for?Histif 5431 Z is used for extrusion blow-moulded L-ring drums and large industrial containers built to UN dangerous-goods packaging standards. It is the reference grade for 1H1 closed-head and 1H2 open-head plastic drums carrying hazardous liquids and solids, where sub-zero drop performance and long-term environmental stress crack resistance are certification requirements.
What's the difference between Histif and mainstream Hostalen HDPE?
Histif: engineered specifically for UN-approved dangerous-goods drums, with notched Charpy impact of 80 kJ/m² at −30 °C for reliable sub-zero drop performance
Hostalen: general-purpose HDPE for blow moulding, beverage closures, pressure pipe and industrial packaging. More economical when sub-zero drop testing is not a certification requirement
Does Histif meet UN dangerous-goods packaging standards? Yes. Histif 5431 Z is built for UN-approved 1H1 closed-head and 1H2 open-head plastic drums, which have to pass drop testing at −18 °C before they can carry hazardous liquids or solids across borders. The grade's low-temperature toughness and ESCR are engineered against that certification profile.
Is Histif suitable for food-contact applications? No. Histif is intended for industrial dangerous-goods duty, not food or medical applications. For food-contact HDPE, see the Hostalen range; for healthcare-grade closures, see Purell ACP6541A.
