High-Performance PA Polymerization & Modification Additives from China Suppliers and Factory
Product Description
Polyamide (also called PA or Nylon) is the generic terms of thermoplastic resin, containing repeated amide group on the main molecular chain. PA includes aliphatic PA, aliphatic-aromatic PA and aromatic PA, in which aliphatic PA, derived from the number of carbon atoms in the synthetic monomer, has the most varieties, the most capability and the extensive application.
With the miniaturization of automobiles, the high performance of electronic and electrical equipment, and the acceleration of the lightweight process of mechanical equipment, the demand for nylon will be higher and greater. Nylon inherent shortcomings are also an important factor limiting its application, especially for PA6 and PA66, compared with PA46, PA12 varieties, have a strong price advantage, although some performance can not meet the requirements of the development of related industries.
Therefore, it is necessary to improve some properties by modification for a certain application field to expand its application field. Because of the characteristics of strong polarity, PA has strong hygroscopicity and poor dimensional stability, but it can be improved by modification.

Frequently Asked Questions
Q
What is Polyamide (PA/Nylon) and what are its main types?
Polyamide (also known as PA or Nylon) is a thermoplastic resin containing repeated amide groups on the main molecular chain. Its main types include aliphatic PA, aliphatic-aromatic PA, and aromatic PA. Among these, aliphatic PA is the most widely used due to its diverse varieties and broad application range. Common grades include PA6, PA66, PA46, and PA12.
Q
Why does Polyamide need modification additives?
PA has inherent shortcomings such as strong hygroscopicity and poor dimensional stability due to its highly polar nature. As industries demand higher performance — particularly in automotive, electronics, and mechanical equipment — standard PA grades like PA6 and PA66 may not fully meet requirements. Modification additives help overcome these limitations, expanding PA's application range and improving properties such as thermal stability, oxidation resistance, and flame retardancy.
Q
What is the role of antioxidants in Polyamide applications?
Antioxidants are critical in PA processing to prevent thermal and oxidative degradation during manufacturing and end use. Products such as YIHOO AN1098 (IRGANOX 1098 equivalent) and YIHOO AO80 provide excellent heat aging protection, especially when used in combination with phosphite ester and macromolecular sulfur antioxidants. They help maintain the mechanical, optical, and electrical properties of PA products over time.
Q
What does the light stabilizer YIHOO LS519 do in PA processing?
YIHOO LS519 (equivalent to NYLOSTAB S-EED, CAS 42774-15-2) functions as a melt stabilizer and melt process modifier. It improves the quality of polyamide products produced through injection molding, blow molding, and extrusion processes. It is also effective in reducing filament breakage rates during fiber spinning, making it especially valuable in PA fiber and film production.
Q
Is YIHOO FR930 flame retardant suitable for glass fiber reinforced nylon?
Yes. YIHOO FR930 is specifically designed for high-temperature nylon applications, offering excellent thermal stability. It is suitable for both glass fiber reinforced and non-reinforced nylon systems. End products treated with YIHOO FR930 demonstrate outstanding physical and electrical properties, making it a reliable choice for demanding engineering applications.
Q
What other polymer additive product series does the company offer beyond PA additives?
In addition to PA polymerization and modification additives, the company offers a comprehensive range of polymer additive series including: PU foaming additives, PVC polymerization and modification additives, PC additives, TPU elastomer additives, low VOC automotive trim additives, textile finishing agent additives, coating additives, cosmetics additives, as well as API and other specialty chemical products such as zeolite.
