In the global consumer electronics, industrial electronics and precision electronic equipment industries, electronic devices are becoming increasingly lightweight, miniaturized and high-precision, putting forward stricter requirements for internal cushioning, sealing and insulation protection. Electronic device silicone foam is a professional flexible protective material specially developed for electronic applications, designed to solve common problems such as internal component vibration damage, dust and moisture intrusion, circuit short circuits and heat accumulation in electronic equipment. Tengye provides high-performance electronic device silicone foam, manufactured with electronic-grade silicone raw materials and precision foaming technology, to deliver safe, stable and long-lasting protection for various precision electronic components and equipment shells.
Electronic-Grade Silicone Material & Precision Foaming Process
Our electronic device silicone foam adopts imported high-purity electronic-grade silicone raw materials, with a halogen-free, low-smoke and environmentally friendly formula, specially optimized for the internal working environment of electronic equipment. We adopt advanced closed-cell or open-cell foaming process to form a uniform and delicate porous internal structure, balancing ultra-soft texture, high resilience and reliable sealing performance, and avoiding material defects that may cause abrasion or corrosion to precision electronic components.
This professional electronic-grade silicone foam features a wide operating temperature range of -60℃ to 230℃, maintaining stable flexibility and resilience even under the long-term heating of electronic components or extreme low-temperature environments, without hardening, cracking, softening or deformation. It has excellent electrical insulation properties, effectively isolating circuits and preventing static damage and short-circuit risks, and also boasts good chemical resistance, resisting corrosion from electronic cleaning agents, weak acids and alkalis. All products comply with RoHS 2.0, REACH, UL 94 V-0 and other international electronic industry certifications, non-toxic, odorless and pollution-free, with authoritative third-party test reports (SGS/Intertek) available for verification.

Precautions for Use
To ensure the performance and service life of electronic device silicone foam, and give full play to its cushioning and protection effects, please abide by the following guidelines during installation and use:
-
Before installation, thoroughly clean the bonding surface of electronic equipment to keep it dry, smooth, free of oil, dust and burrs, ensuring a tight fit between the foam and the equipment surface.
-
Control the compression ratio reasonably during installation, generally controlled at 25%-50%, avoid excessive compression to prevent permanent deformation of the foam, which will affect cushioning, sealing and insulation performance.
-
Store the product in a cool, dry and ventilated environment before installation, avoid long-term exposure to strong sunlight, high-temperature heat sources and open flames, and keep away from corrosive chemicals to prevent premature aging.
-
Select the appropriate product specifications, thickness and performance grade according to the actual use scenario, internal structure of electronic equipment and industry safety requirements.
-
During transportation and installation, avoid sharp scratches and heavy pressure on the foam, so as not to damage the foam structure and affect its normal protection performance.
