🌍 About RUBASIA RUBBERTECH INDUSTRIES PTFE Sheet

RUBASIA RUBBERTECH INDUSTRIES is a leading manufacturer and supplier of high-performance PTFE (Polytetrafluoroethylene) sheets, known commercially as Teflon sheets, across Sabah, Sarawak, and Brunei Darussalam.

Our PTFE sheets are precision-manufactured from virgin, high-purity fluoropolymer resins, offering exceptional resistance to chemicals, temperature, and environmental degradation, while maintaining low friction and superior dielectric performance.

PTFE’s unmatched versatility allows it to replace conventional plastics, rubbers, and even metals in high-demand environments — from chemical process plants, food industries, and oil & gas refineries, to aerospace, pharmaceutical, and semiconductor fabrication facilities throughout Borneo.

 

⚙️ Material Composition and Technical Construction

PTFE (C₂F₄)n is a fully fluorinated polymer consisting of carbon and fluorine atoms bonded in a linear chain structure. The strong C–F bond energy (485 kJ/mol) gives PTFE its unique combination of stability, chemical inertness, and non-stick surface behavior.

Manufacturing Process

1. Cold Compression Moulding of PTFE resin powder.
2. Sintering at 360°C–380°C to achieve uniform density and crystallinity.
3. Cooling & Annealing under controlled conditions to prevent warping.
4. Skiving / Sheet Cutting into precision thicknesses (0.5mm – 6mm).
5. Surface Finishing for uniform gloss and smoothness.

🌡️ Key Technical Properties of PTFE Sheet

1. Chemical Inertness

PTFE’s unique molecular structure makes it resistant to strong acids, alkalis, oxidizers, and organic solvents, including hydrochloric acid, nitric acid, sulphuric acid, ammonia, acetone, benzene, and petroleum derivatives.
This makes it an ideal lining or gasket material for chemical plants in Bintulu, Miri, Labuan, and Brunei’s Seria industrial zone.

2. Thermal Stability

With a continuous working range of -180°C to +260°C, PTFE performs flawlessly in cryogenic systems, heat-sealing bars, and high-temperature chemical reactors.
Even at high heat, it emits no toxic fumes and maintains structural integrity.

3. Low Friction Coefficient

PTFE’s friction level (0.04) is lower than any known solid material, enabling smooth, wear-free movement.
It is the go-to material for bearings, bushings, seals, piston rings, and slide plates in factories from Kota Kinabalu to Kuching.

4. Non-Stick Surface

PTFE’s non-wettable surface prevents adhesion of materials — perfect for heat press liners, packaging seal layers, and mould release plates used in food processing plants across Borneo.

5. Electrical Insulation

With excellent dielectric properties, PTFE is widely used for electronic components, PCB spacers, high-voltage insulation, and RF shielding systems.
Miri, Kuching, and Brunei electronics industries rely heavily on PTFE for safe electrical design.

6. Weather & UV Resistance

PTFE is unaffected by UV light, ozone, humidity, and salt exposure, ideal for coastal environments like Kudat, Semporna, Lahad Datu, Bintulu, and Brunei coastal zones.

7. Non-Toxic and Food Safe

Certified for FDA, EU, and LFGB standards, PTFE is biocompatible and inert — suitable for food packaging, bakery equipment, beverage tubing, and pharmaceutical contact surfaces.

🏗️ PTFE Sheet Installation and Fabrication Techniques

1. Cutting:
   Use carbide-tipped tools or precision CNC cutters. Avoid excessive heat buildup.
2. Bonding:
   PTFE’s non-stick nature requires special etching (sodium-naphthalene treatment) before gluing to metal or other substrates.
3. Machining:
   Excellent machinability for turning, milling, and drilling — suitable for creating custom washers, seals, or spacers.
4. Welding:
   PTFE cannot be welded by conventional means; instead, fusion bonding or heat pressing is used for joining.
5. Storage & Handling:
   Store flat to prevent warping. Avoid stacking under heavy weight for long durations.
