Polyethylene Foam Sheets – 30kg Closed Cell PE Foam Protective Foam

Closed cell polyethylene foam sheets are lightweight, waterproof and highly resilient cushioning materials used for packaging protection, insulation and vibration control. Manufactured with a 30kg density, this PE foam provides the ideal balance of flexibility, strength and long-term durability for industrial and commercial applications.

Available plain or with a high-shear acrylic adhesive backing, this PE foam is ideal for packaging, insulation, acoustic control, flotation and protective padding in demanding environments. Please note this material is acid free.

✅ Important Manufacturing & Lead Time Notice

⚠️ All thicknesses are made to order and manufactured specifically for each customer.
Standard lead time is 4–5 working days. A4 Samples avaliable upon request.

👉 If you require material urgently, please contact our office before ordering and we will advise on current production availability.

✅ Key Performance Features

• Density: 30kg/m³ – lightweight yet durable

• Closed cell structure: Waterproof, airtight and non-absorbent

• High compression recovery: Retains shape under repeated impact

• Strong & abrasion resistant: Long service life

• Chemically resistant: Withstands oils, solvents, acids and alkalis

• Thermal insulation: Low thermal conductivity (~0.030 W/mK)

• UV, ozone & weather resistant: Suitable for indoor & outdoor use

• Flexible yet rigid: Bends without sagging or collapsing

• Optional adhesive backing: High-shear acrylic scrim adhesive

✅ Typical Applications

• Shock absorption for shipping & transit protection

• Tool case inserts, protective padding & custom packaging

• Thermal insulation (pipe lagging, equipment insulation)

• Acoustic soundproofing for walls, floors & machinery

• Damp proofing & insulation layers

• Flotation & buoyancy aids (does not absorb water)

• Vehicle insulation (sound & thermal barriers)

• Gaskets, seals, spacers & protective barriers

• Camping & yoga mats (thicker grades)

• Medical & rehabilitation padding (splints, braces, wheelchair seating systems)

✅ Why Choose Closed Cell Polyethylene Foam Sheets for Shock Absorption?

Polyethylene foam is one of the most effective materials for impact protection and vibration damping. Its closed-cell structure traps millions of air pockets, allowing it to absorb heavy loads and repeated impacts without permanent deformation.

• High impact resistance – protects against knocks, drops & compression

• Lightweight yet durable – strong protection without excess weight

• Moisture resistant – maintains performance in wet conditions

• Versatile use – packaging, construction, flooring & industrial protection

• Long-term performance – resists fatigue, tearing & compression set

Trusted across packaging, construction, medical, automotive and marine industries, PE foam delivers reliable cushioning with excellent cost efficiency.
