Our Main Materials
| Abbreviation | Name | Properties | Operating Temperature Range |
|---|---|---|---|
| PP | Polypropylene | Chemically resistant, lightweight, versatile | Up to 60°C |
| PPGV30S | Polypropylene + glass fiber | Glass-fiber reinforced, dimensionally stable, highly durable | Up to 110°C |
| PVDF | Polyvinylidene fluoride | High-temperature resistant, chemically resistant | Up to 135°C |
From December 31, 2026, this assessment basis will become mandatory for all products in contact with drinking water. We are currently the only supplier in the segment able to demonstrate this approval for all main materials.
Other Materials Processed
Chemical Resistance – Polypropylene (PP)
| Chemical | Concentration | Resistance | Remarks |
|---|---|---|---|
| Sodium hypochlorite (NaClO) | 0.1–0.5% | moderate to good | sensitive at >40°C |
| Chlorine (Cl₂, dissolved) | <1 ppm | moderate | oxidizing – causes damage under prolonged exposure |
| Sulfuric acid (H₂SO₄) | up to 30% | good | stable at room temperature |
| Hydrochloric acid (HCl) | up to 20% | good | resistant |
| Sodium hydroxide (NaOH) | up to 50% | very good | ideal for alkaline solutions |
| Acetic acid (CH₃COOH) | up to 10% | good | higher concentrations may be critical |
| Ammonia solution (NH₃ aq) | up to 25% | very good | no restrictions |
| Hydrogen peroxide (H₂O₂) | <5% | limited | prone to embrittlement |
| Sodium chloride (NaCl) | saturated | very good | fully resistant |
Chemical Resistance – PVDF
| Chemical | Concentration | Resistance | Remarks |
|---|---|---|---|
| Sodium hypochlorite (NaClO) | 0.1–0.5% | very good | also at higher temperatures |
| Chlorine (Cl₂, dissolved) | <1 ppm | very good | excellent resistance to oxidation |
| Sulfuric acid (H₂SO₄) | up to 98% | very good | also at higher temperatures |
| Hydrochloric acid (HCl) | up to 36% | very good | stable |
| Sodium hydroxide (NaOH) | up to 50% | very good | no restrictions |
| Acetic acid (CH₃COOH) | up to 100% | very good | fully resistant |
| Ammonia solution (NH₃ aq) | up to 25% | very good | no restrictions |
| Hydrogen peroxide (H₂O₂) | up to 30% | good | better resistance than PP |
| Sodium chloride (NaCl) | saturated | very good | fully stable |
Colour Coding for Slot Widths
| Slot Width (mm) | Color |
|---|---|
| 0.2 | Ivory |
| 0.3 | Green |
| 0.4 | Black |
| 0.45 | Sea green |
| 0.5 | Gray |
| 0.55 | Brown |
| 0.7 | Yellow |
| 0.8 | Blue |
| 1.0 | Black |
| 1.5 | Orange |
| 2.0 | Blue |
| 2.0 | Green |
| 2.5 | Ivory |
| 2.5 | Black |
| 5.0 | Gray |
Note:
The color code applies exclusively to nozzles made of PP and PPGV30S. PVDF cannot be colored, as the addition of a masterbatch would adversely affect its chemical resistance and mechanical strength. Components made of PVDF are therefore supplied in their natural color (opaque).
