Qiyu silicone rubber for the first time developed a new automotive air conditioning silicone hose
Study on technology of silicone tube from the beginning of the industrial field to the field of today's hospitals and food industries. Recently, Qi Yu rubber developed a can meet the use of a new generation of refrigerants HFO-1234yf requirements of automotive air conditioning hose AC6B 11. The products have been began to automotive air conditioning manufacturers supply the air conditioning hose the main equipment in specifically for the European market models.
Automotive air conditioning hose generally use from the outside to the inside in order to outer rubber, strengthen yarn, rubber inner layer structure, the inner side of the inner rubber in order to prevent the leakage of the refrigerant, usually coated with polyamide resin. HFO-1234yf is in the use of long-term decomposition gradually increased, the properties of acid production. Therefore, the original hose resin is easy to corrosion problems exist. Therefore, new product coated in the inner side of the inner rubber polyamide resin with acid neutralizer used to successfully prevent resin corrosion and leakage of refrigerant.
In the automotive air conditioning refrigerant, HFC-134a is widely used, its destructive effect on the ozone layer than small freon. But with global warming coefficient (GWP), carbon dioxide is 1, while the HFC-134a is up to 1300. Therefore, the automobile air conditioning refrigerant to Europe as the center is to the GWP for HFO-1234yf conversion, and in the future the U.S. auto industry for HFO-1234yf is adopted to estimate the will also increase. Therefore, Qiyu silicone rubber will be aimed at the European automotive air conditioning manufacturers and automobile manufacturers, strengthen the sales of new products.
