PTFE material has the following characteristic
(1)Physical properties: smooth surface, waxy, ivory and opacity, average density is 2.2
(2)Mechanical properties: tensile strength is 20.0~30.0MPa, elongation at break is 300%~400%, modulus
of elasticity is 400 MPA, surface hardness is 55-70HS, friction coefficient between PTFE is 0.1-0.2
(3)Chemical properties: can resist most strong corrosive material, no solvent can’t dissolve, it under
300℃, strong weather ability, can store more than ten years
Advantages:
1. Wear and corrosion resistance
2. Efficiency steaming treatment
3. Reduces friction and ensure smooth rod reaction
4. PTFE banded piston
5. It is equipped with piston rings to provide a good seal between the cylinder wall and piston
6. Increased seal durability
Applications:
Car or motorbike shock absorbers
Competitive Advantage:
