Silicone vs. Natural Rubber: Technical Specifications Breakdown

Recently, I received an inquiry from a customer in Turkey who specializes in the production and sales of woodworking machines. Many of their vacuum laminating machines, used for covering wooden materials with PVC, rely heavily on rubber membrane sheets.

For years, they had been sourcing these membranes from Europe, but due to rising costs, they decided to explore alternative materials from China. To ensure they could find a suitable replacement, the customer shared technical specifications in image form for the membranes they currently sell.

After reviewing and organizing their information, I compiled the following technical data he mentioned for both natural rubber and silicone membranes, making it easier to compare and evaluate potential alternatives.

Understanding the Variability in Technical Specifications

The above specifications serve as reference values, but it’s important to note that each supplier may have slight variations based on:

• Raw material composition
• Manufacturing techniques
• Specific end-use applications

Key Takeaway: Choosing the Right Membrane

A higher specification does not necessarily mean better performance for every machine. Instead, compatibility with your vacuum press, application needs, and budget constraints should be the primary factors in selecting the ideal membrane.

My story with this Turkish customer is still unfolding, and the trial order has already been completed. If you’re interested in the follow-up, I’d be happy to share more details in a separate blog.

In the next section, we will explore the essential factors to consider when choosing between silicone and natural rubber membranes, helping you make a well-informed decision.

Key Considerations for the Right Vacuum Press Membrane

Whether you’re working with wood veneers, solid surfaces, or composites, a well-matched membrane ensures consistent performance, durability, and cost efficiency.

Here are the most important factors to evaluate:

1: Application Requirements: Matching the Membrane to Your Needs

Before looking at materials, start by identifying how the membrane will be used. Different applications require different properties:

• High-temperature thermoforming → Silicone membranes are best due to their 250°C heat resistance.
• Wood veneer and furniture laminating → Natural rubber membranes offer strong tear resistance and flexibility.
• Deep forming or curved surfaces → A thick, highly elastic membrane is ideal.

2: Compatibility with Adhesives & Processing Conditions

Not all membranes work well with all adhesives and press conditions.

• Silicone membranes resist most solvents, chemicals, and adhesives, making them ideal for high-heat vacuum pressing.
• Natural rubber membranes work well with wood veneers and PVC foils but may degrade when exposed to certain adhesives or excessive heat.

Check compatibility with your adhesives, temperatures, and vacuum press settings before making a choice.

3: Material Selection: Durability & Performance

The membrane material determines its resistance to heat, stretching, and wear.

• Silicone → Best for high-heat applications and materials requiring deep shaping.
• Natural Rubber → More cost-effective and suitable for woodworking and laminating applications.
• Polyurethane & PVC → Less common but used for specialized applications requiring moderate flexibility.

For demanding, high-temperature environments, silicone is the clear winner. For cost-sensitive applications, natural rubber is a strong contender.

4: Surface Texture – Why Both Smooth/Smooth and Smooth/Textured Exist

Silicone membranes are typically offered in two surface configurations: smooth/smooth and smooth/textured. So why both?

• Identification Made Easy: Some manufacturers only offer smooth surfaces on both sides, which can make it difficult to distinguish between brands or membrane types during use. By offering a smooth/textured option, it becomes easier to differentiate between the working surface and the backing layer.
• Application Flexibility: In most cases, customers use the smooth side as the working surface. However, the textured side can be beneficial when better airflow or breathability is required—such as in applications that involve curved parts or deep drawing.
• Manufacturing Advantage: From a production standpoint, the smooth/textured configuration helps reduce the risk of air entrapment between layers, resulting in fewer bubbles and a higher yield rate.

At Deer Hunter, both types are readily available. If you’re unsure which one suits your application best, our engineers strongly recommend testing a small sample first—we’ll ship it to you free of charge, including shipping.

5: Thickness: Strength vs. Flexibility

Membrane thickness affects durability and ability to conform to complex shapes.

• 1mm–2mm → Highly flexible, ideal for detailed shaping and deep forming.
• 2.5mm–3mm → Balanced durability and stretchability for general thermoforming and wood lamination.
• 4mm and above → More wear-resistant but less flexible, best for high-pressure applications.

6: Cost: Short-Term vs. Long-Term Value

Price varies based on material, thickness, and supplier, but focusing solely on cost can be misleading.

• Silicone membranes → Higher upfront cost but longer lifespan and better heat resistance.
• Natural rubber membranes → More affordable initially, but may require more frequent replacements.

Instead of just looking at price, consider long-term durability, replacement frequency, and overall cost-effectiveness.

7: Supplier & Product Quality

Reliable suppliers ensure consistent quality and optimal performance:

• Check for certifications and technical data that verify material quality.
• Request samples before placing bulk orders.
• Look for manufacturers offering custom sizing and expert support.

There is no universal best choice—your selection should depend on specific processing needs, material compatibility, and budget.

A well-matched membrane enhances lamination quality, operational efficiency, and overall durability.
