Vicnyl® HTPA materials offer excellent overall performance.
(1) Outstanding high temperature performance
High melting point (Tm up to 325℃)
High transition temperature of vitrification (Tg up to 125℃ in dry state)
High heat distortion temperature (HDT up to 295℃)
(2) Less affected by humid environment or even hot water
(3) Suitable for surface mounting by lead-free reflow soldering
(4) Excellent chemical resistance
(5) Excellent electrical performance
(6) Excellent formability, suitable for rapid thin-wall forming
Vicnyl® HTPA is available in five series.
(1) Vicnyl® HTPA “3”
• Vicnyl® 3 Series is a reinforced semi-aromatic polyamide with high glass fiber content, which has high strength, high rigidity, impact resistance and good appearance. Its performance is less affected by humidity and is suitable for structural parts.
(2) Vicnyl® HTPA “4”
• Vicnyl® 4 Series is a high performance semi-aromatic polyamide that has low water absorption, good chemical resistance, electrical properties and dimensional stability.
(3) Vicnyl® HTPA “5”
• Vicnyl® 5 Series is a high performance semi-aromatic polyamide that has low water absorption, low warpage, good chemical resistance and dimensional stability.
(4) Vicnyl® HTPA “61”
• Vicnyl® 61 Series is a bio-based, high performance semi-aromatic polyamide with extremely low water absorption, good resistance to hydrolysis and alcoholysis, chemical resistance and dimensional stability.
(5) Vicnyl® HTPA “7”
• Vicnyl® 7 Series is a bio-based, high performance semi-aromatic polyamide with extremely low water absorption, excellent resistance to hydrolysis and alcoholysis, chemical resistance and dimensional stability.
The Vicnyl® 61 and 7 series are based on poly (decamethylene terephthalamide) (Vicnyl® PA10T), one of the monomers, the diamine (account for about 50wt% in the weight of total monomer), is derived from renewable resources – ramie beans.
The bio-carbon content of Vicnyl® PA10T material is between 40 wt% and 60 wt%.
Compared to other high temperature resistant nylon materials, the advantages of Vicnyl® PA10T are:
(1) The water absorption rate is much lower than that of PA46, PA4T and PA6T, resulting in higher dimensional stability, higher strength and rigidity retention in humid environments;
(2) Better hydrolysis and alcoholysis than PA46, PA4T and PA6T
(3) Better resistance to reflow soldering than PA46, PA4T and PA6T (MSL 1)
(4) Better color stability
The main application of Vicnyl® HTPA
(1) Application of Vicnyl® PA10T on LED reflection stand
Maintains high whiteness and high reflectance after 3 reflow soldering, high temperature in long time and UV aging treatment
Water absorption is much lower than PA6T, and it has higher dimensional stability for long-term use.
Rapid crystallization, greatly shortens the molding cycle
Good adhesion to lead frames, encapsulating resins (silicone and epoxy)
