Ningbo Changqi Fluoroplastic Products Co., Ltd. was established in 1993 and is a professional manufacturer of polytetrafluoroethylene (PTFE) products. It is a high-tech enterprise, a credit-based AAA enterprise and a tax-based A enterprise. It is the drafting unit of the PTFE raw material belt industry standard.

The more than ten raw material belts operated fully automatic production lines are of advanced level. The invented (with invention patents) raw material tape additive recycling technology and device are leading technology.

The produced ultra-wide, high-precision PTFE calendered films are widely used outside the sealing field. It is also used in insulation fields such as cable wrapping.

The newly developed aviation sealing materials have the main technical indicators such as strength and low temperature performance, tested and approved by the Lanzhou Institute of the Chinese Academy of Sciences. It has attracted the attention of AVIC First Aircraft Design Research Institute.

The newly developed graphite, copper, nickel and other metal materials are filled with PTFE raw materials that have special properties and uses.

The PTFE multi-layer elastic plate, which has now been put into production, has obtained the national key new product certificate issued by the Ministry of Science and Technology, the Ministry of Environmental Protection and the Ministry of Commerce.

The PTFE bidirectional stretched microporous filter membrane that has entered the industrialization is a project of the Ministry of Science and Technology 863. Now the modification technology of microfiltration membrane has been developed successfully, which has changed from hydrophobicity to hydrophilicity and is widely used in the fields of environmental protection and new energy.
