Halogen-free and non-red phosphorus heat shrinkable sleeve introduction
Halogen-free and non-red phosphorus heat-shrinkable sleeve is a flame-retardant heat-shrinkable sleeve that does not contain halogen, does not use phosphorus-based flame retardant, and has no halogen-free red phosphorus heat-shrinkable sleeve made of radiation-crosslinked polyolefin material. Excellent electrical performance, suitable for electrical insulation of high-end fire safety and environmental protection requirements, solder joint rust and corrosion protection, mechanical protection and wire harness protection.
Where does the halogen-free and red-phosphorus heat-shrinkable sleeve come from:
In 2010, Matsushita Electric (China) Co., Ltd. Wuxi Matsushita Refrigeration Co., Ltd. produced a total of 29 models (the number of objects was 365,574) for the B20～B26/C23～C29 series produced between March 2007 and March 2009. The refrigerator issued a recall notice. The explanation for the reason for this recall is: “The red phosphorus flame retardant is used in the parts (refrigerant control valve) that controls the refrigerant (refrigerant). In the high temperature and high humidity environment, the refrigerant control valve coil may be caused. Broken wire, resulting in an abnormal phenomenon that 'refrigerating room is not cold' or 'cooling room is too cold'. When some models of refrigerators are used for a long time under fault conditions, very few products will generate refrigerant control valve refrigerant leakage, in extreme cases There are safety hazards in the case of smoke and fire. In addition, some types of refrigerators in the recall range have similar safety hazards when the L and N poles of the power outlet are reversed.. As soon as this notice came out, it immediately caused the industry's concerns about the use of red phosphorus flame retardants. Various speculations fly over the sky - some people think that in the high temperature and high humidity environment, "red phosphorus" can be converted into "white phosphorus", which will produce spontaneous combustion; some people think that "red phosphorus will produce phosphoric acid when wet, for metal components, electrodes, coils, etc. Corrosive, and even cause quality problems such as disconnection, poor contact, short circuit, etc.; suddenly a stunned, customers began to refuse to use red phosphorus products, so there is a "halogen-free red phosphorus" product. Although the final investigation of this incident was not related to the flame retardant used. But the shadow it left for people still exists, and there is still skepticism about products containing red phosphorus.
REACH certification in the heat shrinkable sleeve industry has a parameter standard for halogen-free and non-red phosphorus heat-shrinkable sleeves. In non-halogen flame retardants, red phosphorus is a better flame retardant with less added amount and resistance. High fuel efficiency, low smoke, low toxicity and wide application. Red phosphorus has been used as a flame retardant for more than 40 years. Since 1965, red phosphorus has become a famous high-efficiency flame retardant.
There are two types of halogen-free and non-red phosphorus heat-shrinkable sleeves: low flame retardant (no phosphorus) and high flame retardant (red phosphorus ≤ 1000ppm). The halogen-free and non-red phosphorus heat-shrinkable sleeve has the characteristics of no halogen, no red phosphorus, low smoke, no toxicity, softness and flame retardancy.
