Adhesive tape material
Finished product
Liang-Haw Technology uses special formula and advanced production technology to develop the substrate of adhesive tape. Due to this type of product has soft and fitting characteristics, it can be used to cover uneven surface. It has the characteristics which cannot be achieved by using the substrate of thin film and paper.
Advantage：
The eFoam series products are cross-linked by electron beam (EB) radiation (without chemical corss-linker, such as DCP). These are closed-cell polyolefin foam products and can be supplied in rolls. Extremely low water absorption or moisture penetration rate. Good weatherability and chemical resistance. Non-toxic, no odor or no volatile organic compounds (VOC). Meet Taiwan EPA Eco Label Class 1 and Class 2. Comply with European Union (EU) RoHS requirements.
Characteristics：
Extremely low water absorption, excellent heat insulation, cold resistance without brittle, long durability, suitable for extensive temperature, UV and chemical resistance, double fine surfaces, can be as thin as 0.5mm with 300%~500% of elongation. The evenness could be controlled within 5%.
Use：
Adhesive tape, vehicle tape, medical foam pad, washer for electronic products, industrial double-layer foam tape, building insulation tape, wallpaper.
