In modern electronics and household appliance manufacturing, the reliability of bonding materials directly affects product safety, durability, and production efficiency. As devices become more compact and assemblies more complex, manufacturers are increasingly demanding adhesive solutions that combine mechanical strength, dimensional stability, and long-term performance. Rubber Based MOPP Tape has emerged as a highly effective solution in this context, offering dependable bonding for applications where stability and resistance are non-negotiable.
Understanding MOPP Tape Technology
MOPP Tape, short for Monoaxially Oriented Polypropylene Tape, is engineered using a monoaxially stretched polypropylene film as its backing material. During the orientation process, polymer chains are aligned in a single direction, creating a highly ordered crystalline structure. This molecular alignment significantly enhances the tape’s mechanical strength and dimensional stability compared to conventional polypropylene films.
One side of the MOPP film is coated with a pressure-sensitive adhesive, while the opposite side is treated with a release agent or undergoes corona treatment to improve surface energy and adhesion consistency. When paired with a rubber-based adhesive system, MOPP Tape delivers both immediate tack and durable long-term bonding.
Key Performance Advantages of Rubber Based MOPP Tape
Exceptional Dimensional and Thermal Stability
Dimensional stability is a critical requirement in electronics and appliance assembly, where even slight material deformation can affect component alignment. Under standard conditions (23±2°C, 50±5% RH), Rubber Based MOPP Tape typically exhibits longitudinal (MD) thermal shrinkage below 1.5%, with high-performance grades achieving levels under 1.0%. Transverse (CD) shrinkage remains significantly lower than that of conventional films.
This stability is achieved through the monoaxial orientation process, which releases internal stress within the film and minimizes its response to temperature fluctuations. As a result, the tape maintains consistent performance during both assembly and long-term use.
Reliable Weatherability and UV Resistance
Polypropylene is inherently inert, making it resistant to oxidation and moisture absorption. The dense crystalline structure of MOPP film further enhances its barrier properties, reducing the risk of adhesive degradation caused by environmental exposure. When combined with appropriate UV stabilizers, Rubber Based MOPP Tape demonstrates strong resistance to ultraviolet radiation, making it suitable for applications where indirect UV exposure or extended service life is required.
Strong Electrical Insulation Properties
Electrical insulation is essential in electronic device assembly. Polypropylene offers excellent insulating characteristics, with a volume resistivity reaching up to 10¹⁶ Ω·cm or higher. This makes Rubber Based MOPP Tape a reliable choice for securing internal components without compromising electrical safety or performance.
Why Choose Rubber-Based Adhesive Systems?
Rubber-based adhesives are valued for their superior initial tack and long-term bonding strength. Unlike some adhesive systems that may lose adhesion over time, rubber-based formulations maintain flexibility and adhesion stability, even under vibration or mechanical stress.
When applied to MOPP film, rubber-based adhesives form a robust bonding system that adheres well to a wide range of substrates, including plastics, painted metals, and coated surfaces commonly found in electronics and household appliances.
Practical Applications in Electronics Manufacturing
Mobile Device Packaging and Assembly
In smartphones, tablets, and other mobile devices, internal space is limited and component placement must be precise. Rubber Based MOPP Tape is widely used for secure mounting of batteries, modules, and structural components within device housings or packaging structures.
Its strong adhesion ensures components remain firmly in place during transportation and daily use, while its dimensional stability prevents stress or warping that could affect sensitive electronic parts.
Household Appliance Assembly
Household appliances such as refrigerators require bonding materials that can withstand mechanical impact, temperature variation, and long-term operational stress. Rubber Based MOPP Tape is commonly used for fixing exterior panels, securing insulation layers, and stabilizing internal components.
The tape’s resistance to shrinkage and environmental factors helps maintain structural integrity, contributing to improved durability and reduced maintenance issues over the product’s lifecycle.
Manufacturing Efficiency and Process Compatibility
From a production standpoint, Rubber Based MOPP Tape supports efficient assembly processes. Its pressure-sensitive adhesive allows for quick application without the need for curing time, reducing assembly complexity and improving throughput. The tape’s consistent thickness and tensile strength also make it suitable for automated or semi-automated application systems.
Manufacturers seeking a balance between performance reliability and process efficiency often turn to Rubber Based MOPP Tape as a dependable bonding solution.
Product Reliability Backed by Material Engineering
The performance of Rubber Based MOPP Tape is not the result of a single feature, but rather the integration of material science and adhesive engineering. The monoaxially oriented polypropylene backing provides structural stability, while the rubber-based adhesive delivers strong, lasting adhesion across diverse applications.

Meeting Industry Demands with Confidence
As electronics and household appliances continue to evolve, bonding materials must keep pace with higher performance standards and stricter quality requirements. Rubber Based MOPP Tape offers a proven solution for manufacturers seeking long-lasting adhesion, dimensional stability, and reliable performance in demanding environments.
By selecting well-engineered materials and adhesives, manufacturers can enhance product reliability, optimize assembly processes, and deliver consistent quality to the market.
