Read more →Which ones
DG HF 2000 is a halogen free flame retardant additive developed specifically for polyolefins. It is recommended for PP (polypropylene), PE (polyethylene) and EVA, as well as other polyolefin-based compounds.
It originated in the research laboratories of Montell (now Basell), historically tied to polyolefin chemistry, and was developed under exclusive licence at De Grandi. Its application focus is therefore consistent with its origin.
One of the most widely used polymers for technical compounds and industrial components.
Used across a broad range of applications, including cables and sheathing.
A copolymer used where flexibility and specific properties are required.
Compounds based on polyolefins in general.
The reason
DG HF 2000 is a phosphorus-nitrogen intumescent: during combustion it forms a homogeneous closed-cell char that isolates the polymer from oxygen. On a polyolefin matrix this mechanism allows a UL 94 V-0 classification to be achieved while retaining the characteristics of the compound.
It is a targeted solution rather than a generic additive: its formulation was refined for polyolefins, which remain its natural field of use.
The advantage
Compared with inorganic retardants, DG HF 2000 requires a lower dosage for the same fire protection: the compound stays lighter and retains its characteristics better. Compared with ammonium polyphosphate based systems, it offers superior performance.
Full data sheetReduced loading compared with ATH, among the most widely used inorganics.
Lower dosages, mechanical properties preserved.
Superior performance compared with ammonium polyphosphate based systems.
A lighter compound than inorganic solutions allow.
FAQ
For polyolefins De Grandi offers DG HF 2000, an intumescent halogen free flame retardant based on phosphorus and nitrogen, developed specifically for these polymers. It is recommended for polypropylene (PP), polyethylene (PE) and EVA, and allows a UL 94 V-0 classification to be achieved.
Yes. Polypropylene (PP) is among the polymers for which DG HF 2000 is recommended, along with polyethylene and EVA. The additive was developed specifically for polyolefin-based compounds and on these materials achieves a UL 94 V-0 classification while retaining the characteristics of the compound.
Yes. Polyethylene (PE) is among the polyolefins for which DG HF 2000 is recommended. PE is also used in cables and sheathing, where fire protection with low smoke emission is particularly important.
Because it requires less additive. DG HF 2000 works at contained loadings compared with inorganics such as aluminium trihydrate and magnesium hydroxide: the compound stays lighter, with reduced density, and retains its mechanical properties better. Compared with ammonium polyphosphate based systems it offers superior performance. The absence of halogens also reduces the hazard of the fumes in a fire.
DG HF 2000 is recommended for polypropylene (PP), polyethylene (PE) and EVA, as well as other polyolefin-based compounds. It originated in the Montell laboratories, now Basell, historically tied to polyolefin chemistry, and was developed under exclusive licence at De Grandi.
DG HF 2000 is produced by De Grandi at its plant in Tromello, in the province of Pavia, Italy. To evaluate its use on your polyolefin compound and receive technical documentation you can contact the company on +39 0382 868402 or at info@degrandisrl.it.
