Recyclable PET Core
Manufactured from recyclable PET thermoplastic material supporting more sustainable composite manufacturing.
Low Resin Uptake
Closed cell foam structure helps minimise resin consumption during infusion processes.
High Shear Strain
Excellent shear strain properties provide improved fatigue resistance in composite sandwich structures.
Thermoformable Material
Easy to machine and thermoform for complex composite shapes and structural panels.
Common Applications
- Composite sandwich panels
- Marine composite structures
- Wind energy components
- Industrial composite panels
- Transportation composite structures
- Architectural composite structures
Technical Specifications
Compare Structural Board & Core Options
| Feature | Divinycell PL100 | Divinycell PL230 |
|---|---|---|
| Material type | PET structural foam core | PET structural foam core |
| Density | Approx. 100 kg/m³ | Approx. 230 kg/m³ |
| Weight | Lighter option | Heavier, higher density |
| Compressive strength | Lower than PL230 | Higher compressive performance for more demanding loads |
| Best suited for | General structural panels, lightweight sandwich construction, marine and industrial composite panels | Higher load areas, more demanding sandwich panels, reinforcement zones and areas needing improved compression resistance |
| Resin uptake | Low | Low |
| Moisture resistance | Very good | Very good |
| Machinability | Yes | Yes |
| Typical choice | When lighter weight and lower cost are priorities | When increased density and load handling are required |
PL100 is generally the lighter PET core option for structural sandwich panels, while PL230 is better suited to higher load applications where improved density and compression performance are needed.
| Feature | Divinycell PL100 | Divinycell PL230 | Coosa Bluewater 20 | Coosa Bluewater 26 | Marine Plywood |
|---|---|---|---|---|---|
| Material type | PET structural foam core | High density PET structural foam core | Fibreglass reinforced polyurethane board | Higher density fibreglass reinforced polyurethane board | Timber based marine panel |
| Density | Approx. 100 kg/m³ | Approx. 230 kg/m³ | Approx. 20 lb/ft³ | Approx. 26 lb/ft³ | Generally heavier than foam cores and often comparable to or heavier than Coosa depending on product |
| Weight | Very light | Light to medium | Lightweight board option | Heavier than Bluewater 20 | Heaviest option here |
| Structural role | Best used as a sandwich core | Best used as a higher density sandwich core | Structural replacement board | Higher strength structural replacement board | Traditional structural sheet material |
| Water resistance | Very good | Very good | Excellent | Excellent | Good initially but more vulnerable over time if exposed |
| Rot resistance | Yes | Yes | Yes | Yes | No |
| Moisture absorption | Low | Low | Very low | Very low | Higher |
| Best suited for | Lightweight composite sandwich panels, decks, hull sides, industrial panels | Higher load sandwich panels, reinforcement zones, demanding structural composite parts | General marine construction, cabinetry, deck cores, transom replacements where lower weight matters | Transoms, heavily loaded structures, premium marine and industrial parts | Traditional boatbuilding, general structural panels, lower cost replacement sheet needs |
| CNC machinable | Yes | Yes | Yes | Yes | Yes |
| Typical choice | When very low weight and sandwich construction are the priority | When higher core density is needed in a sandwich laminate | When replacing timber with a lightweight composite board | When replacing timber in more heavily loaded areas | When using a familiar timber panel and budget is a key factor |
Divinycell PL100 and PL230 are structural PET foam cores typically used inside sandwich laminates, while Coosa Bluewater 20 and 26 are structural replacement boards often used instead of timber. Marine plywood remains a traditional option but carries more risk of moisture related deterioration over time.
