Blade Panels

Panels

GRP faced plywood has been the default panel type in the UK for decades.  Despite being fairly durable, it's heavy, it deteriorates and is virtually impossible to recycle.  Today, Don-Bur offers many options, but which should you choose and why?  Do you specify the lightest, the stiffest, the most resilient to damage or even a recyclable option?

Skin Fixation Strength
Rigidity Scale
Acute Impact Resistance Grade
Environmental Effect Moisture ingress into plywood leading to eventual delamination and core deterioration. Rigidity is affected by variances in heat.  Material also affected by UV light. Material affected by long-term UV light NIL NIL
Damage Degradation Water ingress into plywood leading to delamination, surface deterioration and rot. As above As above Subject to surface oxidisation if paint surface is broken. Self-healing zinc skin.  Subject to oxidisation if galvanised surface is broken.
Flammability Self fuelling active flame. Self fuelling active flame. Includes glass retardant. High heat resistance.  Rated as slow burning. Melting point 660°C  Auto-extinguishes
Recyclability Not recyclable Due to the mixture of compounds these plastic types are hard to recycle and not generally recycled in the UK De-Lamination required. Due to the mixture of compounds these plastic types are hard to recycle and not generally recycled in the UK Smelts to pure recyclable product. Low cost process. Steel skin can be smelted. Polyethylene core is commonly  downcycled in the UK
Absorbency Moisture content fluctuates between 8/12% at time of milling to 30%.  Trailer can fluctuate in weight by +/-240kgs 0.03% 0.1% NIL < 0.01%
