Air Intake Manifolds Manufactured with Chemically Recycled Material Achieve a Reduction of CO
2
Emissions and Costs Saving with Similar Mechanical Resistance
2012-36-0368
In the current Brazilian air intake manifold market, most of the
small car applications use the reinforced polyamide PA 6.6 GF30 as
base material. The glass fiber (30%) guarantees the required
mechanical resistance, necessary once the manifold is assembled on
the engine and is subjected to considerable vibration levels.
Air intake manifolds were developed using a new chemically
recycled material recuperated from yarn production process, called
Technyl ECO, which represents a reduction of 4.3 kg of CO₂
equivalent per 1 kg of polyamide produced. This material can
replace the current one, once it has the same formulation (PA 6.6
GF30) and similar mechanical resistance. Moreover, it represents a
cost saving up to 10% in the raw material.
The air intake manifolds injected with the recycled material
were subjected to the mechanical validation tests under severe
conditions of accelerated aging at temperature of 140°C and thermal
shock with abrupt temperature change from -40°C to 120°C. All
samples were approved according to the specifications for life
under vibration, metallic inserts extraction, bursting, pressure
drop and impact.
