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 rich technical knowledge and extensive production expertise in the development and manufacturing of electrical insulation rubber sheets. We are fully capable of satisfying diverse customer demands in terms of the scale of our production facilities, dielectric grades, thickness and hardness ranges of our products. In our modern production base, we implement a complete and standardized manufacturing process, covering core procedures such as rubber formula mixing, high-precision calendering, professional vulcanization, and strict quality testing. Every step is carried out under standardized management to ensure stable insulation performance, reliable quality and consistent specifications of our electrical insulation rubber sheets.

Our strong production capacity is supported by a complete and advanced production equipment system: 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 automated length measurement system, which greatly improves production efficiency, dimensional accuracy and product consistency.

Ensuring Quality at Every Stage: Product Inspections

Our comprehensive product and manufacturing inspection services are designed to rigorously uphold the quality standards of electrical insulation rubber sheets throughout every stage of the manufacturing process. By implementing systematic inspections, we help you maintain consistent insulation performance, reliability, and compliance with international electrical safety standards and customer requirements. Our professional inspectors conduct thorough verifications to confirm that all rubber sheet specifications are strictly met. These key parameters include dielectric strength, tensile strength, elongation rate, vulcanization time, hardness, color consistency, and dimensional accuracy. Every critical characteristic is checked and documented to ensure the final product aligns with your predefined standards.

To achieve full-process quality control, our inspections cover the entire production lifecycle, from initial manufacturing to final shipment. This includes the initial production check to validate setup and early-stage quality, in-process inspections to monitor ongoing production stability, container loading inspections to safeguard product integrity during packaging, pre-shipment inspections to confirm readiness for delivery, and continuous production monitoring to identify and resolve issues in real time. Through this end-to-end inspection system, we help you minimize defects, improve production efficiency, and deliver high-quality electrical insulation rubber sheets that meet both your expectations and global market demands.

Package: Focusing on efficiency & performance

To ensure the electrical insulation rubber sheets remain in perfect condition during storage and transportation, we have implemented a complete and reliable packaging system. Each roll or sheet is first covered with a protective plastic film to prevent scratches, dust, moisture, and contamination. The rubber sheets are then neatly arranged on sturdy, fumigation-free plywood pallets that meet international export standards. To enhance stability and avoid shifting during transit, we use high-strength packing straps to securely fasten the entire load. Protective corner guards and rubber pads are installed at all potential contact points to avoid pressure marks, deformation, or damage caused by friction or strapping. We also use waterproof, wear-resistant labels that clearly show product specifications, batch number, thickness, size, voltage grade and quantity for easy identification.

For overseas shipments, the entire pallet can be covered with stretch film or waterproof shrink film for extra protection against humidity and rain. With these standardized packaging measures, we ensure that our electrical insulation rubber sheets arrive clean, undamaged, and ready for direct installation at your facility.

FAQs

Q1: What are the core advantages of electrical insulation rubber sheet? 

A1: Electrical insulation rubber sheet boasts excellent dielectric strength to resist high voltage and avoid electric shock risks. It features good abrasion resistance and anti-aging performance, stable physical properties and moderate hardness. It is the essential safety material for power stations, distribution rooms and electrical maintenance work.

Q2: What voltage grades of insulation rubber sheets can you supply? 

A2: We provide insulation rubber sheets covering common grades including 5kV, 10kV, 15kV, 20kV, 35kV. Different thickness corresponds to different withstand voltage standards. We support customized specifications according to local electrical safety standards.

Q3: Can electrical insulation rubber sheets be used in damp indoor environments?

A3: Yes. Our insulation rubber sheets feature good moisture resistance. However, long-term immersion in water is not recommended. Keep the surface dry to maintain its optimal insulation effect and extend service life.

Q4: Can I get free samples of electrical insulation rubber sheet for testing? 

A4: Small test samples are available. Customers only need to bear the courier freight cost. Please inform us of the required voltage grade, thickness, hardness and surface texture for sample arrangement.
