PRECITE® E is our brand for polyethylene-terephthalate compounds. PET-Compounds have higher stiffness and strength than PBT-Compounds with same reinforcement level. PET can be used at elevated temperature and has an excellent surface, even at high temperature.
PRECITE® E – our PET based compounds are the right choice if high stiffness and strength is required at elevated temperature.
PET offers a 20% higher stiffnes than PBT compounds with same fiber content. The excelent surface, even in high reinforced compounds can be also helpfull for tribological applications. As PET is a polyester, it offers excellent dimensional stabilty due no water uptake.
In opposite to most PBT compounds PRECITE® E can also be used for stiff applications in automotive interior like for instance air vents. It reaches good surface quality and complies with requirements of emissions and odor.
- High reinforced for metal replacement
- High surface quality
- Good wear resistance
- Elevated temperature vs. PBT
Compared to other polymers such as PA 66, PA 6 and also PPA, PET Precite E also shows high dimensional stability under moisture. Components can thus be used precisely and independently of environmental influences. The stress-strain curve shows different compounds with 50% glass fibre reinforcement. Compared to standard polyamides, which lose a lot of their mechanical properties after water absorption, PRECITE® E GF 50 natural (7300) does not change at this temperature. It also withstands direct comparison with a PPA compound.
In addition to high stiffness at high elongation, these compounds exhibit a strong bond between matrix and carbon fibre. Even at 80 and 120 °C PRECITE® E - ICF 30 black (7429) still shows good mechanical properties and is therefore already established in various applications in structural components (including interiors): The good surface finish, even with a high degree of reinforcement, is worth mentioning and recommends the material for components with high aesthetic requirements, such as air vents or wiper arms.
PRECITE® E shows unique performace combined with our affordable carbon fibre reinforcement ICF.
The 30% reinforced PRECITE® E ICF 30 black (7429) has a modulus of 25 MPa. Even after 240 days at 80°C / 60% humidity the mechanical performance is still the same. Moreover we measured the modulus at 45°C orientation shows even 15 GPa stifnessand 140 MPa strength.
The good adhesion of our ICF with our polyester compounds is of special importance. Both PBT and PET show an excellent performance even at 45° and 90° orientation of carbon fibres. As shown in the example of PRECITE® E ICF 30 black (7429).
