TPE Material for Electronic Shell Accessories

Strong adhesion without delamination, excellent overmolding compatibility: Using polar modification technology, SEBS grafted with maleic anhydride modified TPE substrate is selected, which has extremely strong chemical affinity with PC, ABS, PC/ABS and other electronic shell substrates. The peel strength at room temperature can reach 5~10N/cm, achieving a firm bonding effect of "peeling TPE without adhesive residue". It can withstand high and low temperature changes and slight impacts without delamination or detachment, perfectly solving the industry pain points of traditional overmolding materials having weak adhesion and easy edge lifting, and adapting to the long-term use needs of electronic shells. At the same time, it matches the thermal expansion coefficients of the substrate and TPE, with reduced bonding strength decay in environments from -40 to 120°C, outstanding stability, and adaptability to different usage environments of electronic devices.

•Eco-friendly and non-toxic, compliant for the electronics industry: Adhering to the concept of eco-friendly R&D, it uses a halogen-free, non-toxic, low-VOC formula, free of harmful components such as heavy metals, phthalates, and nonylphenol, with no odor and no exudation, and can be 100% recycled and reused, aligning with the global sustainable development concept of the electronics industry. It has passed multiple authoritative environmental and electronics industry certifications such as RoHS, REACH, FDA, and UL, and is compliant for high-end scenarios including consumer electronics, medical electronics, and industrial electronics, meeting the core needs of electronic product export trade and domestic compliant sales, and serving as the core raw material support for compliant production by electronic brands.

•Combining rigidity and flexibility, balancing protection and texture: It perfectly integrates the high strength and impact resistance of electronic shell substrates with the soft cushioning and anti-slip properties of TPE. The Shore hardness can be flexibly adjusted from 35 to 90A, providing solid structural support for electronic shells while also offering a delicate and comfortable touch, with no burrs or scratching. The surface has excellent anti-slip effects, effectively preventing electronic devices from slipping, and also has good cushioning performance to alleviate impact damage to electronic shells, enhancing the overall texture and durability of electronic products.

•Weather and corrosion resistant, suitable for multiple scenarios: It has excellent weather resistance, aging resistance, and chemical corrosion resistance, with outstanding UV resistance and oxidation resistance. It can be used long-term in complex environments such as indoors, outdoors, and humid conditions without embrittlement, yellowing, or cracking; it can withstand wiping with common cleaners and disinfectants used in the electronics industry, is not easily eroded, and is suitable for electronic shells in different scenarios such as home appliances, outdoor smart devices, and instrumentation, effectively extending the service life of electronic products.

•Easy to process, cost-effective and worry-free: excellent melt fluidity, strong compatibility with processing temperatures of substrates such as PC and ABS, can be formed through various processes including secondary injection molding, two-color injection molding, and overmolding, without complex pretreatment, without additional tackifiers, processing cycle is 40% shorter than traditional rubber, no material buildup, no flash, reducing waste generation. The raw material is moisture-free and can be put directly into production, and sprue waste can be recycled and reused, significantly reducing manufacturer production costs, suitable for large-scale production needs of electronic housings.

•Customizable appearance, adaptable to diverse designs: the appearance can be provided in natural color, semi-transparent, fully transparent, matte, and other options, supports customizing any color on demand, and can achieve various appearance effects such as glossy, matte frosted, and sandblasted, matching the overall design style of electronic housings, while also enhancing the appearance through contrasting color edging, transparent overmolding, and other methods, meeting the personalized and minimalist design needs of mid-to-high-end electronic products, showcasing brand quality.
