High-temperature heat-shrinkable sleeve/fluororubber heat-shrinkable tube/oil-resistance for aircraft engine has excellent high and low temperature resistance, oil resistance and chemical reagent resistance, especially in places requiring heat resistance (e.g. electrical and hydraulic systems near automobile engines or fuel tanks) and in environments requiring chemical solvent resistance, as well as cable harnesses in these environments. Insulation protection and stress relief to protect electronic and electrical equipment from damage.
Contraction ratio 2:1
High temperature resistance, solvent resistance, chemical corrosion resistance, radiation resistance
Excellent oil resistance
High flame retardancy
PCBs, PBBs, PBBOs, PBBEs and PBDEs, which do not contain chloride compounds, meet the environmental protection requirements of RoHS environmental protection directive and SONY SS00259 standard.
Heat shrinkable sleeve for automobile wiring harness
At present, the market share of heat-shrinkable materials used in automobile manufacturing in China is very low, only about 20%. The global market share of 80% is occupied by the United States and Japan. With the comprehensive adoption of domestic certification in the automobile industry and the advantages in cost, the market share of cable sleeve, wire sleeve and automobile heat-shrinkable sleeve is very low. It is expected to be further improved. Guangzhou Kehong Electronics Co., Ltd. specializes in the production of Teflon high temperature heat shrinkable tubes, automotive special double-wall heat shrinkable tubes and other casing products.
At present, the price of domestic automotive double-wall heat shrinkable sleeve is only 20% - 50% of that of American Rikan and Japanese Sumitomo. According to the analysis of domestic supply situation of automobile industry at present, if all of them are replaced by heat-shrinkable sleeve made in China, the average value of each automobile is about 100-200 yuan, while the price of heat-shrinkable sleeve made abroad is 200-500 yuan. Assuming that the market share of thermal shrinkable sleeve for automobile in China is increased to 40%, and the annual output of 70 million sets worldwide, the market space of thermal shrinkable sleeve for automobile in China will reach about 4.2 billion. At present, the gross interest rate of automotive heat shrinkable sleeve is between 40-50%, which is higher than the average level of the industry.
Halogen-free environmental heat shrinkable sleeve is made of high-quality polymer, which is blended into polymer alloy by scientific formula and mechanical blending. After forming, the product is irradiated by electron accelerator and crosslinked and expanded continuously. Its products have the advantages of softness, flame retardant, fast shrinkage and stable performance. Widely used in wire connection, solder joint protection, wire end, wiring harness, electronic components protection and insulation treatment; body parts and steel structure surface protection; anti-rust and anti-corrosion treatment of related products; identification of wires and other products.

目前国内生产的汽车用双壁热缩套管的价格只有美国瑞侃、日本住友的20%-50%。按照国内目前对汽车行业的供货情况分析，如果全部换成中国产汽车用热缩套管，平均每台汽车的使用价值大概为100-200 元人民币，而使用国外的热缩套管的价格为200-500 元。假设中国汽车用热缩套管的市场占有率提高到40%，全球每年7000 万台的产量计算，中国汽车用热缩套管的市场空间将会达到42 亿左右。而且目前汽车用热缩套管的毛利率在40-50%之间，高于行业平均水平。
