Strong adhesion without delamination, excellent overmolding compatibility: Using polarity modification process, SEBS grafted maleic anhydride modified TPE substrate, with strong chemical affinity to PC, ABS, PC/ABS and other electronic shell substrates, peel strength at room temperature up to 5~10 N/cm, achieving a firm bonding effect of "tear TPE without delamination". It can withstand high and low temperature changes, slight impact without delamination or peeling, perfectly solving the industry pain points of poor adhesion and easy edge warping of traditional overmolding materials, suitable for long-term use of electronic shells. At the same time, it matches the thermal expansion coefficient of the substrate and TPE, with reduced adhesion strength degradation in -40~120℃ environment, excellent stability, suitable for different use environments of electronic devices.
•Environmentally friendly and non-toxic, compliant for electronics industry: Adhering to the concept of environmentally friendly R&D, using halogen-free, non-toxic, low-VOC formula, free of heavy metals, phthalates, nonylphenol and other harmful substances, no odor, no exudation, 100% recyclable, in line with the global electronics industry's sustainable development concept. It has passed RoHS, REACH, FDA, UL and many other authoritative environmental and electronics industry certifications, compliant for high-end scenarios such as consumer electronics, medical electronics, industrial electronics, meeting the core needs of electronic product export and domestic compliant sales, and is the core raw material support for compliant production of electronic brands.
•Rigid and flexible, balancing protection and texture: Perfectly combines the high strength and impact resistance of electronic shell substrates with the soft cushioning and anti-slip properties of TPE. Shore hardness can be flexibly adjusted between 35~90A, providing solid structural support for electronic shells while offering a delicate and comfortable touch, no burrs, non-scratch, excellent surface anti-slip effect, effectively preventing electronic devices from slipping. At the same time, it has good cushioning performance, which can mitigate the damage of collisions to electronic shells, improving the overall texture and durability of electronic products.
•Weather and corrosion resistant, suitable for multiple scenarios: Possesses excellent weather resistance, aging resistance and chemical corrosion resistance, outstanding UV resistance and anti-oxidation ability, can be used long-term in indoor, outdoor, humid and other complex environments without embrittlement, yellowing, or cracking; can withstand wiping with common electronic industry cleaners and disinfectants, not easily eroded, suitable for electronic shells of different scenarios such as home appliances, outdoor smart devices, instruments and meters, effectively extending the service life of electronic products.
•Easy processing, cost reduction and efficiency improvement with less worry: Excellent melt fluidity, strong compatibility with processing temperatures of PC, ABS and other substrates, can be formed by secondary injection molding, two-shot molding, overmolding and other processes, no complex pretreatment required, no additional tackifier needed, processing cycle shortened by 40% compared to traditional rubber, no material accumulation, no flash, reducing waste generation. The raw material contains no moisture, can be directly put into production, and runner materials can be recycled and reused, significantly reducing manufacturer production costs, suitable for mass production needs of electronic shells.
•Customizable appearance, suitable for diverse designs: The appearance can be provided in natural, translucent, transparent, matte and other options, supports custom colors on demand, can achieve glossy, matte, frosted and other surface effects. It can match the overall design style of electronic shells, and also enhance the shell's aesthetics through color-contrast edging, transparent overmolding, etc., meeting the personalized and simplistic design needs of mid-to-high-end electronic products, highlighting brand texture.
