INV-856 Multifunctional Nylon Stabilizer Clariant SEED Alternative

Product introduction
INV-856 is a novel multifunctional nylon additive that combines several beneficial properties in one molecule. Due to its unique molecular structure, INV-856 is resistant to the reducing environment of nylon melts and acts as a melt stabilizer and processing modifier. This effect has been demonstrated by the high stability of nylon melt pressure, resulting in high quality nylon injection and extrusion products, as well as low yarn breakage during fiber spinning.

Features and Benefits

1. Multifunctional stabilizer suitable for nylon
Unique, specially tailored multifunctional additive, compatible with nylon through "molecular recognition" and branched amidation.
2. Improve the processing of nylon melt
Stabilize the nylon melt pressure, smooth the processing process, and reduce fiber breakage during fiber spinning.
3. Increase long-term thermal stability and photostability
It is highly compatible with nylon and bonded with nylon molecules, making its stability to nylon beyond the limit of traditional light stabilizers. It can be used in combination with the acetanilide UV absorber VSU to significantly improve the photostability.
4. Enhance dyeing performance
Due to its basic group and its secondary effect, INV-856 can enhance the affinity of metal dyes and acid dyes, making it stable, economical, ecologically compatible and deep dyeing.
5. Easy to operate
Supplied in crystalline form, it can be added by conventional dosing and metering during melt processing or polymerization.
