Silicone membranes for vacuum presses

Vacuum press membranes, also known as vacuum membranes or silicone membranes, are primarily used in woodworking vacuum presses to bend, form, laminate and veneer both flat and curved workpieces all over the world. Our silicone membranes have earned a strong global reputation owing to their excellent elasticity and long service life.

With a wide working temperature range and superior resistance to both high and low temperatures, our silicone membranes deliver great adaptability across diverse application scenarios. Unlike natural rubber membranes, our silicone rubber membranes are offered in multiple hardness grades, with options of smooth or textured surface finishes. This comprehensive product range allows every customer to select the ideal silicone membrane for veneer pressing, wood bending and composite lamination processes.

Building on our proven market performance, Deer Hunter continues to invest in the research and development of custom thermoforming silicone sheets, which are specially designed to meet the diverse requirements of various industries.

Key Features

It delivers excellent elastic recovery, capable of enduring repeated vacuum pressure and high‑temperature pressing without permanent deformation. It also features good airtight performance to maintain stable vacuum negative pressure throughout production. With a broad temperature resistance range, it works reliably from -40℃ to 180℃ and resists thermal aging effectively. The membrane offers great wear and tear resistance, ensuring a long service life even under frequent mechanical friction. Its smooth surface will never scratch wood, metal or composite workpiece surfaces during operation.

Advantages

Our silicone products feature excellent temperature adaptability and remarkable high‑ and low‑temperature resistance, enabling stable performance even under extreme operating conditions and expanding their applicable scenarios greatly. They also comply with strict safety and environmental standards: non‑toxic and odor‑free, the materials are eco‑friendly and suitable for export applications in the food, medical and consumer goods sectors. Boasting well‑rounded properties including weather resistance, electrical insulation, flame retardancy, high tensile strength and tear resistance, these silicone products help customers lower long‑term maintenance and part replacement expenses. Furthermore, we provide full customization services, with multiple options for color, thickness and dimensions to satisfy the unique export‑oriented application needs of each client.

Applications

Silicone rubber sheets have extensive applications in global export markets, as detailed below:

Owing to their excellent insulating properties, they are processed into sealing elements, gaskets and cushioning components for electronic and electrical equipment. Complying with non‑toxic and eco‑friendly standards, they are also manufactured into accessories for the food and medical industries. Additionally, they can be fabricated into automotive parts that withstand the high and low temperature conditions inside vehicles, insulation and flame‑retardant components for machinery, pipelines and HVAC systems, sealing and protective parts for outdoor equipment, as well as various daily rubber products.

From raw materials to finished products, We do it all.

As a professional rubber sheet manufacturer with more than 15 years of industry experience, we have accumulated profound technical expertise and rich production experience in the R&D and manufacturing of SBR rubber sheets. We are fully capable of satisfying customers’ diverse demands in terms of production capacity, density specifications and product hardness grades. At our modern production facility, we implement a complete set of standardized manufacturing procedures covering key processes including rubber compound mixing, high‑precision calendering, professional vulcanization and strict quality inspection. Standardized management is applied throughout every production step, ensuring our SBR rubber sheets deliver stable performance, reliable quality and uniform specifications batch after batch.

Our strong production capacity is supported by a complete lineup of advanced manufacturing equipment, including 6 open mills, 6 internal mixers, 4 calendering machines, 10 drum vulcanizers and 5 flat vulcanizers. In particular, each drum vulcanizer is equipped with an automatic length measurement system, which greatly improves production efficiency, dimensional accuracy and product batch consistency.

Ensuring Quality at Every Stage: Product Inspections

We provide comprehensive product and in‑process inspection services to uphold strict quality standards for SBR rubber sheets throughout every stage of manufacturing. Systematic inspection protocols ensure stable product performance, reliable quality, and full compliance with both industry standards and customized client requirements. Our experienced QC inspectors conduct thorough testing and verification to confirm that all technical specifications for the rubber sheets are met precisely. Major tested parameters include tensile strength, elongation rate, vulcanization time, hardness, color consistency and dimensional accuracy. All critical performance attributes are inspected and documented to ensure the finished products fully meet your predefined quality standards.

To enforce full‑process quality control, our inspection covers the entire production cycle from the start of manufacturing all the way to final shipment. Our inspection procedures include initial production checks to validate equipment setup and early‑stage product quality, in‑process inspections to monitor ongoing production stability, loading inspections to safeguard product integrity during packaging, pre‑shipment inspections to confirm delivery readiness, plus continuous production monitoring to identify and resolve potential problems in real time. Backed by this end‑to‑end inspection system, we help clients cut defect rates, improve operational efficiency, and deliver high‑grade SBR rubber sheets that meet your expectations and market demands.

Package: Focusing on efficiency & performance

To maintain SBR rubber sheets in excellent condition during storage and transportation, we have established a comprehensive and reliable packaging system. Each roll or sheet is first wrapped in protective plastic film to prevent scratches, dust, moisture and surface contamination. The rubber sheets are then neatly stacked on sturdy fumigation‑free plywood pallets that meet international export standards. High‑strength packing straps tightly secure the entire shipment to enhance loading stability and stop cargo from shifting while in transit. Protective corner guards and rubber cushion pads are installed on all vulnerable contact points to prevent indentation, deformation and abrasion damage caused by friction or strap compression. Furthermore, we attach waterproof, wear‑resistant labels printed with clear details including product specifications, batch number, thickness, dimensions and quantity for fast and easy product identification.

For overseas shipments, each loaded pallet can be wrapped with stretch film or waterproof shrink film to add extra protection against humidity and rainwater. Following these standardized packaging procedures, we ensure that our SBR rubber sheets reach your destination clean and undamaged, and can be put into use right away upon delivery to your premises.

FQAs
