• Long-Lasting Durability: Both materials are known for their durability, ensuring that the sheet maintains its properties even under prolonged use and repeated stress, making it a cost-effective solution.
• Superior Hygiene: The anti-microbial properties of Poron Medical, combined with the hypoallergenic nature of Plastazote LD24, ensure that the sheet remains hygienic and safe for extended contact with the skin.
• Versatile Applications: The unique combination of properties makes this sheet suitable for a wide range of applications, from medical and orthotic devices to protective padding and seating solutions.

Customisation and Fabrication

• Easy to Fabricate: The sheet can be easily cut and shaped to meet specific requirements. Whether you need custom orthotics, padding, or inserts, the dual-layer sheet can be tailored to your exact specifications.
• Remouldable: The Plastazote layer is mouldable, allowing healthcare professionals to create custom fits that adapt to patient needs. This makes it ideal for dynamic and changing requirements in medical treatments.
• Adhesive Compatibility: Both layers are compatible with medical-grade adhesives, ensuring secure bonding in multi-layer constructions and composite devices.

Dual-Layer Poron Plastazote Sheets comprising Plastazote LD24 and Poron Medical represents a pinnacle of material engineering, offering unmatched comfort, support, and durability. Its versatile applications and superior properties make it an essential component in medical, orthotic, and protective solutions. Whether for custom orthotics, protective padding, or supportive devices, this composite sheet is designed to enhance patient care and comfort, setting a new standard in medical material technology.

Why Poron and Plastazote are Combined in Orthotics

Poron® and Plastazote® are often combined in orthotic devices because they each bring unique properties that, when layered together, create a more effective and versatile orthotic for different clinical needs.

1. Complementary Properties

• Poron is a polyurethane foam known for its shock absorption and resilience. It compresses under pressure but returns to shape without permanent deformation, making it ideal for reducing impact forces, especially under high-pressure areas like the heel or metatarsal heads.
• Plastazote is a cross-linked polyethylene foam valued for its conformability, lightweight structure, and low shear/friction surface. It moulds slightly to the foot (especially with heat or pressure) and is widely used in diabetic foot care due to its low risk of causing shear injuries.

When used together:

• Poron cushions impact
• Plastazote reduces shear and moulds to the foot

This synergy allows for both comfort and protection.

2. Layering for Custom Foot Orthotics

In orthotic construction, the materials are often layered for specific functional benefits:

• Poron is used as a middle or bottom cushioning layer to manage shock and dampen ground reaction forces.
• Plastazote is used as a top cover layer, in direct contact with the foot, helping to reduce skin irritation and shear.

3. Clinical Applications

This combination is especially beneficial for:

• Diabetic foot care: Reduces the risk of pressure ulcers through shock absorption and low-friction contact.
• Rheumatoid arthritis and elderly patients: Provides a gentle, forgiving surface with deep cushioning.
• Post-surgical orthotics: Helps prevent pressure injuries during recovery.
• Sports orthotics: Protects against repetitive impact injuries and enhances comfort during high activity.

4. Durability vs Custom-Fit

• Poron resists compression over time, keeping the orthotic effective for longer use.
• Plastazote can be thermoformed or milled to fit the foot precisely, ideal for semi-bespoke or fully bespoke orthoses.

Poron and Plastazote are combined in orthotics because they:

• Enhance comfort and reduce injury risk
• Offer excellent pressure redistribution
• Provide a custom fit with long-lasting shock absorption

Together, they create an ideal material pairing for a wide range of foot health needs, from diabetes care to high-impact sports support.
