Machning & Prototyping Medical Device Turning Plastic CNC Parts

Polyethylene Terephthalate
( PET )
1. Good creep resistance, fatigue resistance, abrasion resistance and dimensional stability.
2. Low abrasion and high hardness, with the largest toughness among thermoplastics.
3. Good electrical insulation performance, little influence by temperature, low water,but corona resistance difference.
4. Non-toxic, weather resistance, good chemical resistance stability, absorption, resistance to weak acids and organic solvents,
but not resistant to hot water immersion, not resistant to alkali.

Polycarbonate
( PC )
1. It has high strength and elastic coefficient, high impact strength, wide temperature range, low forming shrinkage and good
dimensional stability.
2. It has the advantages of high strength, good fatigue resistance, stable size and small creep (little change at high
temperature).
3. Excellent electrical characteristics (stable electrical performance can be maintained in humidity and high temperature, which
is an ideal material for manufacturing electronic and electrical parts), dielectric coefficient: 3.0-3.2 and the arc resistance is
up to 120s.
4. Heat aging resistance: the enhanced temperature index is 120 ~ 140 ºC (outdoor long-term aging is also good) .
5. Solvent resistance: no stress cracking.
6. Tasteless and odorless, harmless to human body, in line with health and safety.
7. It is easy to decompose when encountering water under high temperature and humidity.
 

Polypropylene
( PP )
1. PP is non-toxic, odorless.It is low density. The strength, stiffness, hardness and heat resistance are better than low pressure
polyethylene. It can be used at about 100 degrees. there is no environmental stress cracking problem.
2. It has good electrical properties and high-frequency insulation.It is not easy to be affected by humidity.But it becomes
brittle,not wear-resistant and aging at low temperatures. It's suitable for the production of general mechanical parts,
corrosion-resistant parts and insulation parts.
3. It has excellent anti-hygroscopicity, anti-acid corrosion and anti-solubility. However, it is not resistant to aromatic
hydrocarbon (such as benzene) solvents, chlorinated hydrocarbon solvents etc.
4. Polyethylene is very sensitive to environmental stress (chemical and mechanical effects), easily aging under the action of
heat, oxygen and light.
