Airtech RELEASE-EASE-234TFNP

Release Ease® 234 TFNP

Overview

Release Ease® 234 TFNP is a non-porous PTFE-coated fibreglass release fabric designed for composite moulding applications in aerospace and advanced manufacturing. Engineered to provide reliable release from conventional resin systems, it retains resin during curing while producing a smooth, high-gloss surface finish. Its durable construction allows multiple reuse cycles, helping reduce consumable costs and material waste in composite production.

Key Features & Benefits

• Provides excellent release from conventional resin systems.
• Non-porous construction retains resin during cure.
• Produces smooth, high-gloss moulded surfaces.
• Reusable design reduces consumable costs.
• Hard-wearing PTFE surface offers extended service life.
• Reduces post-mould finishing and polishing time.
• Excellent temperature resistance for demanding cure cycles.
• Suitable for repeated aerospace composite production.

Application Guidelines

• Place the release fabric directly against the composite laminate during lay-up.
• Use on flat or simple-shaped moulds for optimum performance.
• Inspect the fabric before reuse for damage or contamination.
• Test under specific cure cycles where maximum temperatures approach the service limit.
• Clean and store the fabric carefully after use to maximise service life.

Compatibility & Limitations

• Compatible with conventional composite resin systems.
• Non-porous construction retains resin rather than allowing bleed-through.
• Intended primarily for flat and simple mould geometries.
• Maximum operating temperature depends on cure duration and process conditions.
• Tygavac recommends process-specific qualification before production use.
