All delivery costs are shown clearly before you complete checkout.
Materials & product selection
Choosing the right foam sheet depends on how the material will be used.
Key factors to consider include:
- Density: lightweight vs high density foam
- Impact protection requirements
- Flexibility vs rigidity
- Environmental exposure (e.g. moisture, chemicals or repeated handling)
Each category page provides practical guidance on material properties, helping you select the right foam sheet for:
- Packaging
- Protection
- Cushioning
- General-purpose applications
If you already know the material you need, you can order directly using the product specifications provided.
These are three commonly used closed cell foam materials, each suited to different applications.
- Plastazote foam sheets: Closed cell polyethylene foam widely used for packaging, protection and general industrial use.
- Evazote foam sheets: Flexible EVA-based foam offering excellent resilience and repeated impact absorption.
- Supazote foam sheets: High-purity polyethylene foam with consistent structure, often selected for applications requiring reliable performance and cleanliness.
Selecting the correct material helps ensure the foam performs as expected in your specific application.
A closed cell foam sheet is a material where the internal cells are sealed rather than open.
This structure provides:
- Low water absorption
- Good durability
- Reliable cushioning and protection
- Consistent long-term performance
Closed cell foam is widely used for packaging, transport protection and general-purpose cushioning.
Services & additional support

- Contact Kewell Converters for practical advice
Our goal is simple: to help you choose the right foam and order with confidence.
Material surcharges in technical foam
What UK manufacturers need to know
Recent reporting across UK manufacturing and plastics sectors highlights widespread cost increases and supply chain disruption, particularly in technical foam materials.
Below answers some of the most common questions we’re being asked by customers and partners.
Material surcharges are being driven by a combination of global factors affecting supply chains.
These include:
- Geopolitical tensions impacting raw foam material availability
- Volatility in energy markets
- Increased production and transportation costs
- Supplier-led price adjustments across specialist materials
Recent industry reporting indicates that cost pressures are now widespread across plastics and related sectors.
Not all foam materials are affected equally.
Surcharges are currently being seen across selected technical foam materials, particularly those used in:
- Aerospace and aviation applications
- Defence and military equipment
- High-performance industrial environments
These foam materials often involve specialist manufacturing processes and are more sensitive to global supply conditions.
In most cases, surcharges are introduced as temporary measures to manage short-term market volatility.
However, the duration can vary depending on:
- Stability of global supply chains
- Energy costs
- Ongoing geopolitical developments
As a result, timelines are not always fixed and are reviewed regularly.
Recent industry data suggests that the vast majority of plastics and materials manufacturers are experiencing cost increases, with many reporting significant disruption to supply chains and pricing.
In practical terms, this means:
- Surcharges are becoming more common
- Lead times may fluctuate
- Pricing stability is harder to guarantee in the short term
Suppliers are taking steps to reduce the impact wherever possible.
These include:
- Using existing stock to delay cost increases
- Negotiating with material manufacturers
- Optimising production planning
- Reviewing material usage and efficiencies
At Kewell Converters, we focus on clear communication and practical support to help customers plan effectively.
Surcharges are typically applied as a percentage adjustment to affected foam materials or products.
To maintain transparency:
- They are clearly shown within quotes or pricing breakdowns
- They relate to specific foam materials or product types
- They are reviewed in line with supplier updates
If you have any questions, our team will be happy to explain.
There are several practical steps that can help manage cost and supply risk:
- Plan ahead where possible to secure foam materials earlier
- Review foam material specifications to ensure they remain the best fit
- Maintain close communication with suppliers
- Consider alternative design approaches where appropriate
Early planning and collaboration can make a significant difference.
In some cases, alternative design approaches may help reduce cost or improve availability.
However, this depends on the application, particularly in sectors such as aerospace, defence and medical, where performance and compliance are critical.
A technical review is often required to ensure any changes meet the necessary standards.
Lead times may be impacted where foam material availability is constrained.
This can vary depending on:
- The material type
- Order volumes
- Supplier capacity
We recommend discussing timelines early in your project.
Material volatility highlights the importance of proactive supply chain management.
Many organisations are now:
- Forecasting demand earlier
- Reviewing supplier strategies
- Reducing reliance on multiple suppliers
- Prioritising reliability and technical support
Recent reporting from UK manufacturing and plastics industry publications highlights the scale of current cost pressures and supply chain disruption.
