Additive for Polyamide(Nylon)

Polyamide Introduction

PA is an abbreviation of polyamide which is a semi-crystalline polymer, also known as Nylon. There are two types: those made of one basic material (e.g.PA 6) and those made of two basic materials (e.g. PA66). They can occur both naturally (e.g. wool and silk) and synthetically (e.g. nylon).

Baoxu Additives for Nylon

Baoxu Chemical Supply Antioxidants, Colorants, flame-retardants, Heat Stabilizers, Impact Modifiers, Lubricants, Nucleating Agents, OBAs, and UV Stabilizers for Nylon plastics.  Both Function and Processing Additive for Nylon, We Simply Plastic Compounding.

Antioxidant for Nylon

Polymer antioxidants can be added to improve the shelf life of the product or to improve its high-temperature stability. while adding a stability margin during thermal processing. Antioxidant BX AO 1098, and BX AO 168 is used a general purpose Antioxidant for NYLON, BX AO 626, 627, 9228 an be used for high-performance Antioxidant for Nylon.

Pigment and Dyes for Nylon

Colorants give color to polymers, plastics, coatings, inks, and fiber. Every color we see in our daily life is related to colorants. For industry usage colorants, we offer organic pigments, solvent dyes, fluorescent pigments, and titanium dioxide. In the colorant portfolio, our products are analogs to BASF and other brands.

Pigments that are targeted for polyamide spin dyeing, apart from being extremely heat stable, must also be chemically fast to the highly reducing medium of the PA melt. Spinning temperatures are between 250 and 290°C, depending on the type of polyamide. As with polyester extrusion, only very few polycyclic pigments are suitable for this purpose. There are no organic yellow pigments that satisfy the specifications. Pigment preparations are also available for this purpose.

Pigment for Nylon

Pigment suited for Nylon is listed below;

Solvent Dyes for Polyamide(Nylon)

Solvent Yellow 21, Solvent Orange 63, Solvent red 122, Solvent red 214, Solvent blue 70, and Solvent blue 132 are frequently used in coloring polyamide.

Flame Retardant for Nylon

Combustion could occur when a substance is heated to its flammable temperature in the presence of oxygen. Flame retardants are generally designed to provide a particular level of resistance to ignition or flame spread. This is achieved by suppressing oxygen availability, building up of char at the surface, inhibiting the combustion reaction within the flame area, or by other mechanics.

non halogen flame retardant for polyamide(nylon)

For halogen-free flame retardant for PA,  aluminum diethyl phosphinate ADP and MPP is recommended.  MCA can also be used in non-glass fiber-reinforced polyamide as a flame retardant.

halogen flame retardant for polyamide(nylon)

Brominated flame retardant and antimony trioxide are used together as halogen flame retardants for polyamide(Nylon).

Compatibilizer & Impact Modifiers for Nylon

Impact Modifiers are substances that increase the durability of molded or extruded plastics, especially those that need to be constantly subjected to impact forces like cold weather. They are added to compounded materials to provide performance features. They provide strength and break resistance to the product for which they are added. They also provide rigidity to the product to prevent it from wrapping or sagging during everyday use. POE-G-MAH, and EPDM-G-MAH are used for Nylon as impact modifiers. Baoxu Chemical offer impact modifier for Nylon as table below

Lubricant for Nylon

Lubricants are a kind of additive used to improve the processing and appearance of polymers. The function of lubricants is to reduce friction, improve fluidity and mold release during resin or compound processing, and increase the surface smoothness of products. EBS, PETS can be used as lubricant for Nylon.

Nucleating Agent for Nylon

Nucleating agent which also known as clarifying agent(clarifiers), improve the crystallization of semi-crystalline polymers. BX NA 101, BX NA 102 can be used for PBT and Nylon, equal to Clariant.

Optical Brightener for Nylon

Optical brighteners are used to mask yellow or increase the whiteness of plastics, inks, coatings, paper, and fiber. OB1 and KSN can be used in NYLON as optical brighteners.

UV Stabilizer for Nylon

UV stabilizers contain two types of light stabilizers: Ultraviolet Light Absorbers (UVA) and Hindered-Amine Light Stabilizers (HALS), used individually or as blends. UVA filters harmful UV light and helps prevent color change and delamination of coatings, adhesives, and sealants. HALS trap free radicals once they are formed and are effective in retaining surface properties such as gloss and preventing cracking and chalking of paints. The combination of these two families is highly synergistic. UV absorber BX UV 329. BX UV 234, BX UV 312 can be used in NYLON as UV Stabilizer.

Heat Stabilizer for Polyamide(Nylon)

There are many types of heat stabilizers that can be used in polyamide, amine, phenolic, organic and inorganic phosphates, copper salt-based, the iodide. They are used are blends to achieve different performances in polyamide. Baoxu Chemical offer bruggolen H10 the same performance heat Stabilizer BX AO H10. We also offer iodide group heat stabilizers.
