Material Overview – Why PTFE Sheet Is the Ultimate Industrial Polymer
RUBASIA RUBBERTECH’s PTFE Sheet, manufactured from 100% virgin polytetrafluoroethylene resin, is recognized globally as one of the most inert and versatile materials in engineering plastics.
It possesses an extraordinarily low coefficient of friction, the widest operating temperature range (-180°C to +260°C), and complete chemical resistance to nearly all industrial reagents — including acids, alkalis, solvents, hydrocarbons, and oxidizers.
Because PTFE is non-stick, non-wettable, and non-reactive, it is a problem-solving material in harsh conditions where other plastics, rubbers, and metals fail.

CNC-machined PTFE components resist friction, wear, and chemicals — ideal for OEMs and maintenance workshops.
- Shaft Liners & Valve Seats:
Reduce energy loss and wear in moving assemblies.
- Bridge Expansion Bearings:
In construction, PTFE sheets act as low-friction sliding interfaces between concrete structures, allowing controlled movement under temperature changes.
Used in:
OEM and infrastructure projects across Sabah (Kota Kinabalu, Tawau) and Sarawak (Miri, Bintulu, Sibu).
5. Medical, Pharmaceutical & Laboratory Environments
Primary Functions: Sterility, non-reactivity, and contamination-free surface.
Detailed Applications:
- Lab Benchtops:
PTFE sheets line work surfaces exposed to solvents, acids, and reagents.
- Sterile Equipment:
Forms liners, test containers, and sample trays for sterilized environments.
- Biotech Reactors:
PTFE gaskets and diaphragms ensure no chemical leaching during sensitive pharmaceutical reactions.
- Medical Implants:
Due to biocompatibility, PTFE is used in joint implants, catheters, and surgical seals.
Used in:
Kuching General Hospital, Queen Elizabeth Hospital (Kota Kinabalu), Raja Isteri Pengiran Anak Saleha Hospital (Brunei).
6. Marine & Offshore Engineering
Primary Functions: Corrosion protection, sealing, and low-friction motion.
