LEONA™ S series is an alloy grade of semi-aromatic polyamide (PA) with polyamide 66 (PA66) or polyamide 6 (PA6).
By creating an alloy with a semi-aromatic polyamide, we have successfully overcome the problems of the dimensions changing and the material properties degrading after absorption of water, which are issues with PA66 and PA6. At the same time, the LEONA™ S series also offers a specific strength comparable to die-cast
The product lineup offers the following three grades (series).
Good appearance/high strength: SG
Good appearance/high strength/flame retardant: SN (non-halogen/non-red-phosphorus flame retardant), SH (halogen flame retardant)
Good appearance/weather resistant: SU
This page introduces the LEONA™ SG series. The LEONA™ SG series is an alloy grade of PA66 with semi-aromatic polyamide which is reinforced with glass fiber and is suitable for a wide range of products and applications including automobile interior and mechanical parts, household appliances, and home fittings.
Painting options can be omitted using the LEONA™ SG series. The part can immediately be adopted after injection molding without going through the secondary painting process. Omitting the painting process also allows cost reduction which is an important factor in all industries.
PA66 general grades, which contain a large amount of GF for strength and rigidity, have the disadvantage that GF floats on the surface, giving the surface a crumbly appearance and making it difficult to use in products that are visible to the human eye. The LEONA™ SG series, however, does not show GF floating and produces a glossy molded product.
Also, since good-looking parts can be obtained even at low injection molding speeds, a wide range of production conditions can be handled.
The LEONA™ SG series can be used for applications such as automobile interiors due to low odor, low VOC, and low fogging. For example, it meets the VW standards (PV3900, PV3015, and PV3341) as shown in the following table.
LEONA™ SG series has higher fluidity than normal PA66+GF high filling materials, and can be processed and molded with a general injection molding machine. Excellent fluidity allows for flexible design and processing. The figure shows the flow length of spiral flow.
Since it is possible to mold large-sized molded products as well as thin-walled and complicated-shaped molded products, it can contribute to metal substitution and product miniaturization and weight reduction.
A component used to fix a mirror for checking rearward vision.
In recent years, housings for forward detection ADAS components are also integrated. High appearance without coloring and rigidity to prevent blurring are required.
Oil pumps for engines, brakes, etc., and cooling pumps for batteries, etc.
Since the product consists of multiple molded parts, good moldability is also required.
