PTFE Filled Article

We have come forward to provide you a wide gamut of PTFE filled article that mainly includes PTFE filled article. 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. We have carved a niche as one of the leading PTFE article manufacturers and suppliers in India. 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
  • Decreased thermal expansion
  • Improved abrasion resistance
