With professional Filled PTFE Article factory, Ningbo Kaxite Sealing Materials Co.,Ltd is one of the leading China Filled PTFE Article manufacturers and suppliers.

Product Detail

[ Features ]

Filled PTFE article is manufactured by moding method with filled PTFE resin. Filled PTFE resin is manufactured by compounding PTFE granular resin with fillers of many differents kinds. Amongst the many fillers suitable for compounding with PTFE, glass fiber, carbon fiber, Bronze and also lubricating materials like graphite, molybdenum disulphide, have been widely used in large scale production, Broadly speaking PTFE compounds have the following advantage over unfilled.

PTFE.

Improved compression strength

Improved thermal conductivity

Dereased thermal expansioin

Improved abrasion resistance
