How does Hyfran Plus stack up against the competition? Let's compare it to three common materials.
| Feature | Hyfran Plus | Standard Rubber Foam (NBR) | Polyurethane (PUR/PIR) | Mineral Wool | | :--- | :--- | :--- | :--- | :--- | | Water Absorption | Virtually Zero (<1%) | Moderate (5-10%) | Low (<2%) | High (Sponge-like) | | Compression Set | Excellent (<15%) | Fair (>25%) | Excellent (Rigid) | Poor (Crumbles) | | UV Resistance | Good (Requires coating for long term) | Poor (Degrades rapidly) | Poor (Chalking/Disintegration) | Good (But gets wet) | | Flexibility | High (Can bend around elbows) | High | Low (Needs fittings) | Zero (Needs cutting) | | Install Speed | Fast (Glue & Press) | Moderate | Slow (Multiple layers) | Slow (Vapor seals required) | hyfran plus
The Verdict: For dry, indoor HVAC, standard rubber might suffice. For wet, cold, or heavy-load scenarios, Hyfran Plus wins by a significant margin. How does Hyfran Plus stack up against the competition
| Property | Traditional Superplasticizer (SNF) | Hyfran Plus (PCE) | |----------|-------------------------------------|-------------------| | Max water reduction | 20–25% | 30–40% | | Slump retention | 30–60 minutes | 90–120 minutes | | Dosage range | 0.8–2.0% by cement weight | 0.2–1.5% by cement weight | | Chloride content | May contain up to 0.2% | Chloride-free (<0.1%) | | Compatibility with cement | Sensitive to C₃A | Wide compatibility | For wet, cold, or heavy-load scenarios, Hyfran Plus
Hyfran Plus exhibits controlled retardation through "delayed adsorption." The PCE molecules initially remain in solution, gradually adsorbing onto hydrating cement grains over 60–120 minutes. This prevents slump loss, making it ideal for ready-mix concrete transported over long distances or hot-weather concreting.
When combined with anti-washout agents, Hyfran Plus produces cohesive, non-dispersible concrete that flows through tremie pipes without washout.
Walking into a -20°C freezer warehouse, you will often find Hyfran Plus used as floor insulation panels or door frame thermal breaks. It resists the freeze-thaw cycle that turns standard concrete or wood into crumbling hazards. Furthermore, its closed-cell structure prevents ice crystal formation inside the material itself.
